Abstract
BACKGROUND Flushing is a common dermatologic complaint and can be resistant to many treatments. As the utility of botulinum toxin continues to expand, recent data suggest that it may also be a therapeutic option for flushing. OBJECTIVE To evaluate the efficacy of botulinum toxin for the treatment of cutaneous flushing. MATERIALS AND METHODS A systematic search of Medline, Embase, Cochrane CENTRAL, CINAHL, Scopus, and Web of Science databases was conducted to identify studies evaluating the effect of botulinum toxin on flushing 1 month after treatment. Prespecified outcome measures included a clinical flushing score, dermatology life quality index (DLQI), and erythema index (EI). Meta-analysis was performed to calculate the mean differences in these outcomes before and after treatment at 1-month follow-up. RESULTS Nine studies (132 patients) were included in the analysis of this study (2 randomized controlled trials and 7 nonrandomized studies). All studies had a low risk of bias (high quality). The most frequent outcome reported was a clinical flushing score, which significantly decreased by 1.25 points overall (95% confidence interval [CI]: -2.47; -0.04) 1 month after treatment with botulinum toxin. Mean DLQI scores decreased (i.e., improved) by 9.02 points (95% CI: -19.81; 1.77) 1 month after botulinum toxin injections. The EI (measured by Mexameter) before and after botulinum toxin was evaluated in 2 studies; however, not enough statistical information was provided to analyze with meta-analytic techniques. CONCLUSION Based on this meta-analysis, botulinum toxin significantly improves clinical flushing scores 1 month after treatment.

Abstract
BACKGROUND The concept of "skin boosters" has evolved, marking a shift from traditional uses of hyaluronic acid (HA) fillers primarily for augmenting skin volume to a more diverse application aimed at improving dermal conditions. Restylane Vital and other HA fillers have been repurposed to combat skin aging and wrinkles by delivering HA directly to the dermis. OBJECTIVES This review aims to define the term "skin booster" and to discuss the various components that constitute skin boosters. It seeks to provide a comprehensive overview of the different ingredients used in skin boosters, their roles, and their impact on enhancing dermal conditions. METHODS A comprehensive review was conducted, focusing on representative skin booster ingredients. The approach involved analyzing the different elements used in skin boosters and their specific roles in enhancing dermal improvement. RESULTS The findings indicate that skin boosters, encompassing a range of ingredients, are effective in improving the condition of the skin's dermis. The review identifies key ingredients in skin boosters and their specific benefits, including hydration, elasticity improvement, and wrinkle reduction. CONCLUSIONS Skin boosters represent a significant development in dermatological treatments, offering diverse benefits beyond traditional HA fillers. This review provides valuable insights into the constituents of skin boosters and their effectiveness, aiding readers in making informed decisions about these treatments. The potential of skin boosters in dermatological practice is considerable, warranting further research and application.

Abstract
BACKGROUND Rosacea is a chronic inflammatory disease usually associated with persistent erythema and periodic flushing. This disease is difficult to treat, and the outcomes are often unsatisfactory and prone to recurrence. In recent years, botulinum toxin has been used as a new treatment for rosacea; however, its efficacy and safety remain under discussion. Although a systematic review of the effectiveness and safety of botulinum toxin has been previously conducted by other researchers, our systematic review and meta-analysis evaluate the efficacy of botulinum toxin from a more comprehensive and detailed perspective to provide evidence for clinicians. METHODS Any study using botulinum toxin for the treatment of rosacea was considered for the analysis. RESULTS A total of 22 studies were included, 9 of which were randomized controlled trials involving 720 subjects. After treatment, all studies showed varying degrees of improvement in patient signs and symptoms along with reduced Clinician's Erythema Assessment (CEA) scores. The improvement was maintained for several months, and the adverse effects were mild and self-limiting. CONCLUSION Botulinum toxin may be an effective treatment for patients with rosacea; however, further clinical evidence is needed to confirm its long-term efficacy and side effects. The study was preregistered with Prospero (CRD42022358911).

Abstract
The off-label use of botulinum toxin type-A (BoNT-A) in treating rosacea seems encouraging, but the evidence is still lacking regarding its efficacy and safety. This study was conducted to summarize the evidence regarding the efficacy and safety of BoNT-A in the treatment of rosacea patients. A comprehensive literature search was conducted in several databases, and 17 studies were included. Before-after and split-face comparisons showed that BoNT-A significantly alleviated the symptoms of facial erythema and flushing and improved the patient's quality of life/satisfaction. However, the symptoms recurred three to six months post-injection, requiring repeated treatments in some patients. The pooled rates of post-injection localized erythema, ecchymosis, and facial muscle affection represented 24.6%, 5.1%, and 4.3%, respectively. BoNT-A seems to be effective in alleviating the symptoms of rosacea with a low rate of adverse events. However, the recurrence of the symptoms a few months after the injection requires repeated sessions, which may raise cost-effectiveness issues. Large-scale clinical trials are required to confirm the effectiveness and define the optimal dosing regimen and the rate of recurrence. Future studies should allow for an adequate follow-up after the treatment, with repeated measurements of the outcomes.

Abstract
Rosacea is a multifactorial chronic inflammatory dermatosis characterized by flushing, nontransient erythema, papules and pustules, telangiectasia, and phymatous alterations accompanied by itching, burning, or stinging, the pathophysiology of which is not yet fully understood. Conventional topical treatments usually show limited efficacy due to the physical barrier property of the skin that hinders skin penetration of the active ingredients, thereby hampering proper drug skin delivery and the respective therapeutic or cosmetic effects. New advances regarding the physiopathological understanding of the disease and the underlying mechanisms suggest the potential of new active ingredients as promising therapeutic and cosmetic approaches to this dermatosis. Additionally, the development of new drug delivery systems for skin delivery, particularly the potential of nanoparticles for the topical treatment and care of rosacea, has been described. Emphasis has been placed on their reduced nanometric size, which contributes to a significant improvement in the attainment of targeted skin drug delivery. In addition to the exposition of the known pathophysiology, epidemiology, diagnosis, and preventive measures, this Review covers the topical approaches used in the control of rosacea, including skin care, cosmetics, and topical therapies, as well as the future perspectives on these strategies.

Abstract
BACKGROUND Botulinum toxin injection is a common cosmetic procedure often used to treat dynamic wrinkles, but it has also been observed to have a lightening effect on the skin. It is thought that this lightening effect develops due to muscle innervation blockage; however, the change in the amount of melanin levels has not been quantified. METHOD Thirty-one patients who presented to the dermatology clinic of a tertiary hospital for botulinum toxin injection for wrinkle treatment were included in the study. A standard dose of botulinum toxin was injected to each patient's forehead, glabellar, and crow's feet region, and then the melanin index (MI) was measured with the Mexameter® MX 18 (Courage + Khazaka Electronic, Köln). RESULTS After botulinum toxin treatment, a statistically significant decrease was found in the forehead and upper face MI. The upper face total baseline MI was significantly lower in the Glogau 1 group than in the Glogau 2 group (P = 0.033). The forehead 15th day MI was significantly lower in the Glogau 1 group than in the Glogau 2, 3, and 4 groups (P = 0.030). DISCUSSION Botulinum toxin application to healthy skin for wrinkle treatment can cause facial skin lightening by reducing MI. It was also remarkable that this decrease was more pronounced in the forehead, which is a region that is particularly vulnerable to sun exposure, compared to other regions. Younger people, who are included in the Glogau type 1 group, may benefit more from this lightening effect.

Abstract
Introduction The persistent erythema and flushing seen in some cases of rosacea do not respond effectively to, or may easily relapse after, oral medication or light-based therapies (laser or intense pulsed light). Intradermal botulinum toxin A (BTX-A) injection can be used to treat intractable erythema and flushing, but studies with large samples and long-term observation have not been conducted to determine its effectiveness and safety. The aim of this study is thus to investigate the effective duration and safety of intradermal BTX-A injection for intractable erythema and flushing. Methods Sixteen patients with rosacea with erythema telangiectasia were injected with BTX-A at 1-cm intervals between each point. Clinician Erythema Assessment (CEA) scores were obtained at baseline and 1 month after injection. Flushing assessment and survey using the Dermatological Quality of Life Index (DLQI) questionnaire were conducted at baseline and at 1, 3, and 6 months after injection. Results At 1 month after injection, CEA scores revealed significant improvements in erythema and flushing; the results of the questionnaire on flushing and DLQI indicated that the improvement of flushing usually lasted for 3–6 months, but the effect decreased significantly at 6 months, and individual patients needed another treatment. Conclusions BTX-A significantly improves the symptoms and quality of life of patients with refractory rosacea with few adverse effects.

Abstract
Tetanus and botulinum neurotoxins cause the neuroparalytic syndromes of tetanus and botulism, respectively, by delivering inside different types of neurons, metalloproteases specifically cleaving the SNARE proteins that are essential for the release of neurotransmitters. Research on their mechanism of action is intensively carried out in order to devise improved therapies based on antibodies and chemical drugs. Recently, major results have been obtained with human monoclonal antibodies and with single chain antibodies that have allowed one to neutralize the metalloprotease activity of botulinum neurotoxin type A1 inside neurons. In addition, a method has been devised to induce a rapid molecular evolution of the metalloprotease domain of botulinum neurotoxin followed by selection driven to re-target the metalloprotease activity versus novel targets with respect to the SNARE proteins. At the same time, an intense and wide spectrum clinical research on novel therapeutics based on botulinum neurotoxins is carried out, which are also reviewed here.

Abstract
BACKGROUND As an alternative to other approaches to facial rejuvenation, the air toxin technique (dermal injection of air with micro-doses of botulinum toxin) is a promising method. We aimed to describe this novel technique and assess the overall safety and efficacy of the air toxin technique in facial rejuvenation. MATERIALS AND METHODS A retrospective chart review was performed on cases treated with the air toxin technique. A total of 47 Korean patients underwent a single treatment session. Treatment efficacy was assessed objectively with serial VISIA® (Canfield Scientific, NJ, USA) skin analysis data and subjectively based on the patients' assessment scores at week 12. RESULTS A significant improvement in Wrinkle (p < 0.001), UV spot (p < 0.001), and Porphyrin (p = 0.005) were objectively seen at 12-weeks follow-up. Patients noted improvement in the categories Wrinkle (p < 0.01), Redness (p = 0.029), Texture (p < 0.001), Dilated pore (p < 0.001), and Lifting (p < 0.001) at week 12 compared to baseline. No major adverse event was reported. CONCLUSIONS Our data show that the Air toxin technique is efficacious in facial rejuvenation as shown by improved skin analysis parameters and patient assessment scores. Notably, there was some discrepancy between the objective and subjective parameters of improvement.

Abstract
Rosacea is a chronic cutaneous disorder affecting primarily the face, characterized by erythema, transient or persistent, telangiectasia, and inflammatory lesions including papulo-pustules and swelling. The essential component of the disease is the persistent erythema of facial skin. Episodes of flushing (acute-subacute intermittent vasodilation) are common. Swelling and erythema of the nose along with dilatation of the pilosebaceous poral orifices, known as rhinophyma, can be noted in chronic cases. Rosacea affects up to 10% of the world population and is especially noted in fair skinned individuals aged 35 to 50. Women are affected more often than men. Several treatment modalities including topical medications, systemic drugs, lasers and light-based therapies have been used for the management of rosacea with variable results. Topical medications such as azelaic acid, metronidazole, and sulfacetamide/sulphur, oral antibiotics such as tetracyclines, and oral retinoids alone or, most commonly, in combination form the mainstay of treatment. Light therapies such as intense pulsed light and pulsed dye laser are best used for the eythemato-telangiectatic type. Topical brimonidine, oxymetazoline, ivermectin, tacrolimus, pimercrolimus, low-dose modified release tetracyclines and botulinum toxin are the new additions to the therapeutic armamentarium. This article provides a comprehensive review of the various therapies used for rosacea.

Abstract
Botulinum toxin is a neurotoxic protein produced by Clostridium botulinum, the bacterium responsible for botulism. Botulinum toxin was first used for therapeutic indications in the 1970s for the treatment of strabismus. With greater understanding of its underlying physiology and safety profile, the use of botulinum toxin has now expanded to a range of cosmetic and medical indications. We performed a systematic review of current literature on the applications of botulinum toxin on off-label esthetic uses. Electronic databases were searched for original published studies including randomized trials, observational or cohort studies, as well as relevant case reports. To add to the body of evidence, our review summarizes and synthesizes key study characteristics, results, and level of evidence for each use case. Although the body of evidence remains weak, there is increasing support for the use of botulinum toxin in emerging off-label esthetic uses of botulinum toxin in dermatology.

Abstract
Botulinum toxin (BoNT) is a neurotoxin produced by the Clostridium botulinum bacterium with a well-known efficacy and safety profile in the focal idiopathic hyperhidrosis treatment. BoNT comprises seven different neurotoxins; however, only toxins A and B are clinically employed. BoNT is lately practiced in off-label therapies for a variety of skin diseases. Scar prevention, hyperhidrosis, rhytides, eccrine nevus, alopecia, psoriasis, Darier disease, bullous skin disease, pompholyx and Raynaud's phenomenon are some of the novel indications for BoNT in cosmetic and notably non-cosmetic aspects of dermatology. To employ BoNT correctly in clinical practice, we must have a thorough understanding of the functional anatomy of the mimetic muscles. An intensive literature search was conducted to update all dermatology-oriented experiments and clinical trials on the described element of BoNT for this general overview of BoNT use in dermatology. This review aims to analyse the role of BoNT in dermatology and cosmetology.

Abstract
Botulinum toxin A (BTX-A) injections have become the most popular noninvasive cosmetic procedures performed worldwide. With growing interest, investigators continue to uncover an expanding array of aesthetic indications for BTX-A. Botulinum toxin A has been used off-label in the management of masseter hypertrophy for facial slimming, platysmal bands, nasal 'bunny' lines, perioral rhytides, gummy smile and scars, to name a few. Interestingly, the injection of multiple microdroplets of dilute BTX-A into the dermis, sometimes referred to as 'microbotox', has been investigated as a tool for facial rejuvenation. A handful of prospective studies and case series have demonstrated the benefit of BTX-A in the treatment of facial erythema and improving skin texture. The aim of this review is to summarize and appraise currently available data on the role of BTX-A in treating facial erythema and skin quality, with a special focus on potential pathophysiologic mechanisms.

Abstract
Background Rosacea is a chronic skin disorder characterized by erythema, flushing, telangiectasia, papules and pustules, phymatous changes, and ocular involvement. The aim of this study was to examine all published research articles in which botulinum toxin was used to treat rosacea and to evaluate the efficacy and safety of this treatment. Methods PubMed, Embase, Cochrane Library, and Web of Science database were used to identify articles eligible for systematic review on March 26, 2021. Prospective or retrospective studies which directly used botulinum toxin to treat rosacea were included and reviewed. Results Nine studies were included in this systematic review. Two were randomized controlled trials, graded as Level 2 for the quality of evidence. The total number of participants was 130, and the number of participants in each study ranged from 1 to 25. The improvement was observed in all studies in signs and symptoms compared with baseline. Adverse events were transitory and self-limited. Conclusion Botulinum toxin could have overall satisfying efficacy and safety in the treatment of rosacea, though limited by small sample size, imperfect study design, and short follow-up visits.

Abstract
Botulinum toxin is a superfamily of neurotoxins produced by the bacterium Clostridium Botulinum with well-established efficacy and safety profile in focal idiopathic hyperhidrosis. Recently, botulinum toxins have also been used in many other skin diseases, in off label regimen. The objective of this manuscript is to review and analyze the main therapeutic applications of botulinum toxins in skin diseases. A systematic review of the published data was conducted, following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Botulinum toxins present several label and off-label indications of interest for dermatologists. The best-reported evidence concerns focal idiopathic hyperhidrosis, Raynaud phenomenon, suppurative hidradenitis, Hailey–Hailey disease, epidermolysis bullosa simplex Weber–Cockayne type, Darier’s disease, pachyonychia congenita, aquagenic keratoderma, alopecia, psoriasis, notalgia paresthetica, facial erythema and flushing, and oily skin. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and doses protocols for off label applications.

Abstract
BACKGROUND Rosacea is a chronic inflammatory disease of the skin, relatively more frequent in women over 30 with a low phototype and proven genetic predisposition. Although its etiology is unknown and possibly multifactorial, the immunological abnormality, associated with neurovascular dysregulation and triggering factors, are important elements in its pathophysiology, which lead to the main changes of inflammation, vasodilation, and angiogenesis that are responsible for the clinical manifestations. Despite the lack of cure, numerous therapeutic options are available for the different clinical presentations of the disease, with satisfactory responses. OBJECTIVE To reach a consensus, with recommendations from experts, on the therapeutic management of rosacea suitable to the Brazilian setting. METHODS The study was conducted by five specialized dermatologists from university centers, representatives of the different Brazilian regions, with experience in rosacea, who were appointed by the Brazilian Society of Dermatology. Based on the adapted DELPHI methodology, the experts contributed through an updated bibliographic review of the scientific evidence, combined with personal experiences. RESULTS The group of experts reached a consensus on the relevant aspects in the therapeutic management of rosacea, providing information on epidemiology, pathophysiology, triggering factors, clinical condition, classification, quality of life, and comorbidities. Consensus was defined as approval by at least 90% of the panel. CONCLUSION Despite the impossibility of cure, there are several therapeutic alternatives specific to each patient that provide excellent results, with chances of total improvement and long periods of remission, promoting a positive impact on quality of life. This consensus provides detailed guidance for clinical practice and therapeutic decisions in rosacea.

Abstract
PURPOSE This study aimed to investigate the regeneration effect of extracorporeal shock wave therapy (ESWT) on hypertrophic scar regeneration using objective measurements. METHODS This was a double-blinded, randomized, controlled trial of 48 participants who had undergone autologous split-thickness skin grafting (STSG) with same artificial dermis. The ESWT group (n=25) received shock waves with low-energy flux density (0.05-0.30mJ/mm2). The interval between treatments is a 1-week. The ESWT group also received recommended treatment. The control group (n=23) only received standard treatment. We measured skin characteristics before treatment and after 6 weeks for both groups. RESULTS No significant intergroup difference was noted at the initial evaluations (p>0.05). The pre- to post-treatment change in the scar thickness (p=0.03) and erythema (p=0.03), greater reduction was found in the ESWT group than control group. The pre- to post-treatment change in the sebum level (p=0.02), more increase was found in the ESWT group. We found no significant differences in the change measurements between the two groups for melanin levels (p=0.62) and transepidermal water loss (TEWL) (p=0.94). The changes (skin distensibility, biological skin elasticity, gross skin elasticity, and skin viscoelasticity) measured with the Cutometer showed no significant differences between the two groups (p=0.87, p=0.32, p=0.37, and p=0.29, respectively). CONCLUSION This is the first report of ESWT on hypertrophic scar after burn using objective tools (melanin, erythema, sebum, TEWL, elasticity and thickness). ESWT has objective beneficial effects on burn-associated scar characteristics.

Abstract
Intradermal injection of botulinumtoxinA (BoNT/A) has been used off-label by many clinicians for the purpose of face-lifting effect. Some studies on AbobotulinumtoxinA (AboA) demonstrated clinical efficacy on face-lifting effect when comparing to normal saline solution (NSS). So far, there is no split-face comparison study on face-lifting effect of IncobotulinumtoxinA (IncoA). The objective of this study was to compare the face-lifting effect of IncoA intradermal injection and NSS. Twenty-two subjects were enrolled and randomly injected with IncoA at 1:6 cc dilution (100 unit or 1 vial in 6 cc of NSS) on one side, and NSS on the other side by using intradermal injection technique. Standardized photographic documentation with 2-, and 3-dimentional imaging system (Vectra H1, Canfield Scientific, Inc., Fairfield, NJ) were obtained at baseline, and at 2 weeks after treatment. The face-lifting effect was graded by the subjects and two blinded dermatologists, using photographic comparison. Side effects were also recorded at the end of the study. Immediate face-lifting was identified on the side that was treated with IncoA by blinded injectors in 63.6% of patients. Of all subjects, 17 (77.3%) have noticed the improvement of skin laxity on the side that was treated with IncoA at 2 weeks after treatment. The difference in facial contouring volume measured by Vectra H1 imaging system on IncoA side was significantly higher (P = .033) when comparing to NSS side in patients aged <36 years old. However, there was no statistically significant difference in face-lifting when comparing between IncoA and NSS evaluated by two blinded dermatologists (P = 1.00). Facial asymmetry was found in 36.4% of subjects. This study demonstrated the face-lifting effect of IncoA intradermal injection. Further studies with larger number of subjects and proper method of evaluation should be done to verify these findings.

Abstract
Rosacea is a chronic inflammatory cutaneous disorder that adversely affects patient's health and quality of life due to the complex course and the need for repeated treatment. The exact molecular mechanisms of rosacea are unclear. Mast cells are innate immune cells that can be found in virtually all tissues. Recently, increasing evidence has indicated that mast cells have important effects on the pathogenesis of rosacea. In this review article, we describe recent advances of skin mast cells in the development of rosacea. These studies suggested that mast cells can be an important immune cell that connected innate immunity, nerves, and blood vessels in the development of rosacea. Moreover, we review the inhibition of mast cells for the potential treatment of rosacea.

Abstract
Botulinum toxin (BTX) is a neurotoxin derived from the Clostridium botulinum bacterium that inhibits the release of acetylcholine at the neuromuscular junction level whose effects has been used for many years to treat a variety of muscular/neuromuscular conditions and more recently also for cosmetic use. BTX has experimented in some dermatological conditions, which include Rosacea and facial flushing treatment with good results. The complex mechanism underlying those results is not completely understood but was proposed a release inhibition of acetylcholine from peripheral autonomic nerves of the cutaneous vasodilatory system combined with the blockade substance P and calcitonin gene-related peptide (CGRP) thus modulating blood vessel dilatation. We analysed the published data on BTX off label applications rosacea and flushing retrieved from PubMed.

Abstract
Treatment with botulinum toxin is widely viewed as safe, effective and largely devoid of serious side effects. There are two classes of Botox-related adverse events – transient and benign events, and potentially serious events. The aim of this study was to provide an overview of Botox-related side effects and advise potential management and preventive strategies. Benign side effects are well-localized, reversible and self-limited complications which develop within a few days of the injection, and they usually disappear without any treatment. The aesthetic and functional adverse effects are associated with different muscle responses to botulinum toxin or with misplacement of botulinum toxin. The serious events are sequelae due to the systemic spread of toxin leading to botulism.

A Pilot Study to Evaluate the Efficacy and Safety of Treatment with Botulinum Toxin in Patients with Recalcitrant and Persistent Erythematotelangiectatic Rosacea. Ann Dermatol 2018; 30:688-693. [PMID: 33911508 PMCID: PMC7992459 DOI: 10.5021/ad.2018.30.6.688] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2018] [Revised: 06/26/2018] [Accepted: 07/23/2018] [Indexed: 12/18/2022] Open
Abstract
Background There are few pharmacologic options to reduce erythema and flushing in patients with recalcitrant erythematotelangiectatic rosacea (ETR). We previously reported two cases of refractory flushing and erythema of rosacea that were successfully treated with intradermal botulinum toxin injection, and additional research is needed to prove the efficacy and safety of this treatment. Objective To report the efficacy and safety of botulinum toxin injection as an aid in persistent erythema of rosacea patients. Methods A total of 20 Korean patients with recalcitrant ETR were enrolled to receive treatment by injection of botulinum toxin. Patients received one treatment of intradermal botulinum toxin injection and were assessed 1, 2, 4, and 8 weeks after treatment. The severity of erythema and telangiectasia was investigated by a non-treating physician, and the Erythema Index (EI) was assessed by mexameter at each visit. Patient satisfaction and any adverse events were also assessed at each visit. Results 17 patients completed all follow-up visits and were included in the analysis. Intradermal injection of botulinum toxin significantly reduced erythema severity and EI in ETR patients. Patients reported a satisfaction score of 2.94±0.56 at 8 weeks after treatment. Except for three patients who discontinued the study early due to inconvenience of facial muscle paralysis, 17 patients participating in the final analysis did not report side effects except injection pain at the time of the procedure. Conclusion Intradermal injection of botulinum toxin can be used as an effective and relatively safe adjuvant agent for recalcitrant and persistent erythema of ETR patients.

Abstract
PURPOSE Rosacea is a common, chronic facial skin disease that affects the quality of life. Treatment of facial erythema with intradermal botulinum toxin injection has previously been reported. The primary objective of the study was the safety and efficacy of thermal decomposition of the stratum corneum using a novel non-laser thermomechanical system (Tixel, Novoxel, Israel) to increase skin permeability for Botulinum toxin in the treatment of facial flushing of rosacea. METHODS A retrospective review of16 patients aged 23-45 years with Fitzpatrick Skin Types II to IV and facial erythematotelangiectatic rosacea treated by Tixel followed by topical application of 100 U of abobotulinumtoxin. A standardized high-definition digital camera photographed the patients at baseline and 1, 3, and 6 months after the last treatment. Objective and subjective assessments of the patients were done via Mexameter, the Clinicians Erythema Assessment (CEA), and Patients self-assessment (PSA) scores and the dermatology life quality index (DLQI) validated instrument. RESULTS The average Maxameter, CEA, and PSA scores at 1, 3, and 6 months were significantly improved compared with baseline (all had a P-value <0.001). DLQI scores significantly improved with an average score of 18.6 at baseline at 6 months after treatment (P < 0.001). Self-rated patient satisfaction was high. There were no motor function side-effects or drooping. CONCLUSION Thermal breakage of the stratum corneum using the device to increase skin permeability for botulinum toxin type A in the treatment of facial flushing of rosacea seems both effective and safe.

Abstract
Since its approval by the US Food and Drug Administration in 2002 for glabellar wrinkles, botulinum toxin (BTX) has been widely used to correct facial wrinkles. As a result, many consider BTX synonymous with cosmetic dermatology. Recent studies indicate that BTX elicits biological effects on various skin cell types via the modulation of neurotransmitter release, and it seems that BTX has a wider zone of dermatologic influence than originally understood. Clinicians and researchers are now beginning to explore the potential of BTX beyond the amelioration of facial lines and encouraging results are seen with BTX in a variety of skin conditions. In this paper, we review novel dermatological indications of BTX which includes (but not limited to) scar prevention, facial flushing, post-herpetic neuralgia and itch. These areas show great promise, but there is definite need for larger, double-blinded, randomized control trials against established treatments before BTX becomes a clinical reality.

Abstract
BACKGROUND Botulinum neurotoxin (BTX) A possesses various biological activities, including anti-inflammatory and antipruritic actions. Human and animal studies have shown that BTX is effective in treating histamine-induced itch, lichen simplex chronicus, psoriasis, rosacea, allergic rhinitis, and scar prevention. However, its effect on atopic dermatitis (AD) has not been studied yet. OBJECTIVE To examine the effect of BTX on AD using a mouse model. The primary outcome was skin thickness and transepidermal water loss (TEWL), and the secondary outcome was the alteration in skin severity scores, histological, and laboratory test results. METHODS Forty-two NC/Nga mice (a mouse model for AD) were allocated into 6 groups (the untreated, 2-Chloro-1,3,5-trinitrobenzene [TNCB] alone, TNCB + BTX 30 U/kg, TNCB + BTX 60 U/kg, TNCB + vehicle [0.9% saline], TNCB + 0.03% tacrolimus). Those of the BTX group received intradermal injections of BTX on the rostral back once on the day of TNCB sensitization. The effect of BTX in TNCB-treated NC/Nga mice was assessed by measuring skin thickness, TEWL (primary outcome), the skin severity scores, histological changes of test skin including mast cell count, interleukin (IL)-4 mRNA and protein expression, and total serum IgE (secondary outcome). RESULTS A single intradermal injection of BTX significantly suppressed skin thickness and TEWL in the TNCB-applied skin. The clinical severity scores, acanthosis and mast cell infiltration, were less in the BTX groups. BTX injection also inhibited TNCB-induced increase in IL-4 mRNA and protein expression in mice, but its effect on serum IgE level was not significant. CONCLUSION The preliminary results suggest that BTX may be a novel approach to the prevention and supplemental treatment of acute AD lesions.

Abstract
Rosacea (in German sometimes called 'Kupferfinne', in French 'Couperose' and in Italian 'Copparosa') is a chronic and frequently relapsing inflammatory skin disease primarily affecting the central areas of the face. Its geographic prevalence varies from 1% to 22%. The differential diagnosis is wide, and the treatment is sometimes difficult and varies by stage of rosacea. For erythematous lesions and telangiectasia, intense pulsed light (IPL) therapy and lasers are popular treatment option. In addition, a vasoconstrictor agent, brimonidine, has recently been developed. For papulopustular rosacea, topical antibiotics, topical and systemic retinoids, as well as systemic antibiotics are used. A topical acaricidal agent, ivermectin, has undergone clinical development and is now on the market. In the later stages, hyperplasia of the sebaceous glands develops, resulting in phymatous growths such as the frequently observed bulbous nose or rhinophyma. Ablative laser treatments have largely replaced classical abrasive tools. Here, we reviewed the current evidence on the treatment of rosacea, provide a guideline (S1 level) and discuss the differential diagnosis of rosacea.

Abstract
The use of neuromodulators for therapeutic and cosmetic indications has proven to be remarkably safe. While aesthetic and functional adverse events are uncommon, each anatomic region has its own set of risks of which the physician and patient must be aware before treatment. The therapeutic usages of botulinum toxins now include multiple specialties and multiple indications. New aesthetic indications have also developed, and there has been an increased utilization of combination therapies to combat the effects of global aging. In the second article in this continuing medical education series, we review the prevention and treatment of adverse events, therapeutic and novel aesthetic indications, controversies, and a brief overview of combination therapies.

Abstract
BotulinumtoxinA (BoNT-A) is now widely established for the main approved indication of reducing glabellar lines, and is also widely used off-label to improve the appearance of wrinkles and lines in other parts of the face. The number of aesthetic procedures continues to increase as the patient population becomes more diverse, in particular with increasing numbers of people of color and men. Further developments in treatment may continue to expand the audience for BoNT-A by making procedures more comfortable and by delivering a more natural, less static appearance. These may be achieved through use of combinations of BoNT-A with other aesthetic procedures, tailoring the dose of toxin to the patient's muscle mass or by using novel injection and application techniques. Beyond amelioration of facial lines, encouraging results have been seen with the use of BoNT-A to improve the appearance of hypertrophic and keloid scars and even to prevent them. Studies have been conducted with scars in various parts of the body and further research is ongoing. Dermatological and other medical uses for BoNT-A are also active areas of research. Injections of BoNT-A have been shown to reduce signs and symptoms of acne, rosacea, and psoriasis, to reduce neuromuscular pain, and to bring about significant improvements in a number of rare diseases that are caused or exacerbated by hyperhidrosis. This paper reviews these new uses for BoNT-A, looking at the rationale for their use and discussing the results of published case studies and clinical trials. These areas have shown great promise to date, but more and larger clinical studies will be required before these treatments become a clinical reality. To this end details are also provided of clinical trials currently listed in the main clinical trials database to highlight research areas of particular interest.

Abstract
BACKGROUND Botulinum toxin is a neurotoxin produced by the bacterium Clostridium botulinum which causes a flaccid muscle paralysis. It is currently used for aesthetic treatments and in the focal hyperhidrosis. Recently, botulinum toxin has also been used experimentally in many other dermatological conditions with good results. OBJECTIVE To review and analyze the possible botulinum toxin off-label applications published. METHODS A retrospective review of the published data was conducted. CONCLUSIONS this potent drug can lead to several off-label indications of interest for dermatologists. Further clinical trials are still needed to better understand the real efficacy and safety of these applications and to standardize injection and dose protocols.
