A comparison of the effectiveness of azelaic and pyruvic acid peels in the treatment of female adult acne: a randomized controlled trial

A novel professional-use synergistic peel technology to reduce visible hyperpigmentation on face: Clinical evidence and mechanistic understanding by computational biology and optical biopsy

Topicals and chemical peels are the standard of care for management of facial hyperpigmentation. However, traditional therapies have come under recent scrutiny, such as topical hydroquinone (HQ) has some regulatory restrictions, and high concentration trichloroacetic acid (TCA) peel pose a risk in patients with skin of colour. The objective of our research was to identify, investigate and elucidate the mechanism of action of a novel TCA- and HQ-free professional-use chemical peel to manage common types of facial hyperpigmentation. Using computational modelling and in vitro assays on tyrosinase, we identified proprietary multi-acid synergistic technology (MAST). After a single application on human skin explants, MAST peel was found to be more effective than a commercial HQ peel in inhibiting melanin (histochemical imaging and gene expression). All participants completed the case study (N = 9) without any adverse events. After administration of the MAST peel by a dermatologist, the scoring and VISIA photography reported improvements in hyperpigmentation, texture and erythema, which could be linked to underlying pathophysiological changes in skin after peeling, visualized by non-invasive optical biopsy of face. Using reflectance confocal microscopy (VivaScope®) and multiphoton tomography (MPTflex™), we observed reduction in melanin, increase in metabolic activity of keratinocytes, and no signs of inflammatory cells after peeling. Subsequent swabbing of the cheek skin found no microbiota dysbiosis resulting from the chemical peel. The strong efficacy with minimum downtime and no adverse events could be linked to the synergistic action of the ingredients in the novel HQ- and TCA-free professional peel technology.

A Comprehensive Bibliographic Review Concerning the Efficacy of Organic Acids for Chemical Peels Treating Acne Vulgaris

Acne vulgaris stands out as the most prevalent skin disorder among teenagers and young adults, causing physical discomfort and considerable economic and psychological burdens on individuals and society. A wide range of topical and systemic therapies are available in acne treatment. Chemical peeling is a skin resurfacing technique designed to rebuild healthy skin using exfoliating substances, a simple and affordable process with various dermatological uses. Chemical peels, classified as superficial, medium, and deep, have been utilized for acne vulgaris and multiple other skin issues. In these chemical peels, a diverse range of chemical substances is employed, each with its unique mode of action. Among these, α-hydroxy and β-hydroxy acids have gathered attention for their efficacy in reducing acne lesions and enhancing overall skin appearance. Acids, such as salicylic acid, glycolic acid, or lactic acid, are commonly used in chemical peels due to their exfoliating and sebum-regulating properties. Despite the widespread use of these acids, there exists a lack of consensus regarding the most effective acid type and concentration for treating acne-prone skin. This review aims to bridge this knowledge gap by evaluating the effectiveness and safety of various organic acids used in chemical peels specifically for acne-prone skin. The findings of this comprehensive bibliographic review indicate that organic acid-based chemical peels represent effective and safe treatment options for individuals with acne-prone skin. Their adaptability sets these treatments apart; the choice of organic acid can be tailored to meet individual patient needs and tolerability levels. This personalized approach ensures that patients receive optimal care while minimizing the risks associated with the treatment. As research in this field progresses, it is anticipated that a more nuanced understanding of the ideal acid type and concentration will emerge, further enhancing the efficacy and safety of chemical peels for acne-prone skin.

Role of macrophage scavenger receptor 1 in the progression of dyslipidemia in acne vulgaris patients

BACKGROUND

Macrophage scavenger receptor 1 gene (MSR1), is responsible for producing macrophage scavenger receptors. MSR1 is primarily located on the surfaces of various macrophage types and is known to exert a range of effects on the human body. These effects include influencing innate and adaptive immunological reactions, as well as contributing to the development of conditions such as atherosclerosis, dyslipidemia, liver and lung disease, and cancer. The unregulated assimilation of lipoproteins by MSR1 leads to the creation of macrophages rich in cholesterol that manifest as foam-like cells, ultimately contributing to dyslipidemia. This occurrence highlights the significance of MSR1 as a key player in the pathophysiology of dyslipidemia.

AIM

In this study, we aimed to estimate variation in lipid profile in acne vulgaris (AV) patients. Also, we aimed to investigate the role of MSR1 in lipid profile variation.

SUBJECTS AND METHODS

A case-control study consisting of 100 patients with AV and 104 healthy controls. Lipid profiles were assessed using normalized enzymatic processes and genotype analyses were performed by a polymerase chain reaction and standard Sanger sequencing. Predictions of variant effects were performed using in silico tools.

RESULT

Our results indicated that the levels of lipid profile were higher in patients with AV than in healthy patients. The two haplotypes that were most prevalent in the patients were TCAC (16.5%) and CAGG (15.47%), whereas the two haplotypes that were more prevalent in the controls were TAAC (16.43%) and CCAC (15.62%). IVS5.59 C > A and rs433235 A > G are in linkage disequilibrium. Additionally, rs433235 A > G has a significant linkage disequilibrium with rs3747531 C > G. In silico analysis, tools indicated that the rs433235 A > G variant was disease-causing.

CONCLUSION

Patients diagnosed with TCAC and CAGG exhibited a higher prevalence compared to healthy patients with TAAC and CCAC. The linkage disequilibrium between rs433235 A > G and IVS5.59 C > A has been established. Furthermore, there appears to be significant linkage disequilibrium between rs3747531 C > G and rs433235 A > G. These findings support the notion that genetic variations may play a critical role in the pathogenesis of these conditions.

The Effectiveness of Pyruvic Acid Peeling in Improving the Quality of Life of Patients with Acne Vulgaris

Improving the quality of life (QoL) of patients with various chronic diseases has become a challenge and priority of contemporary medicine. The aim of this study was to assess the impact of pyruvic acid peeling on the QoL of patients with acne vulgaris. The study group consisted of 200 young patients (mean age 23.04 ± 4.71) with acne vulgaris of mainly mild or moderate severity. Basic data about the patient were collected using a self-reported questionnaire. The assessment of QoL was carried out using standardized questionnaires: CADI (Cardiff Acne Disability Index), DLQI (Dermatology Life Quality Index), SWLS (Satisfaction With Life Scale), and BDI (Beck Depression Inventory). The cosmetic intervention consisted of chemical peeling with 35% pyruvic acid for acne lesions on the body and included four series repeated at 7-day intervals. This study demonstrated that acne vulgaris impairs the quality of life of young people. There were no significant differences between the severity of acne and the lifestyles of the subjects. The applied cosmetic procedure significantly decreased the severity of the acne and improved the quality of life of the patients.

Efficacy of Oxybrasion and Cosmetic Acids on Selected Skin Parameters in the Treatment with Acne Vulgaris

Purpose

The present study aimed to evaluate the efficacy of an oxybrasion treatment applied alone and an oxybrasion treatment combined with cosmetic acids in improving acne-prone skin and selected skin parameters.

Patients and Methods

A single-blind placebo study in a sample of 44 women diagnosed with acne vulgaris was conducted. Group A (n = 22) had a series of five oxybrasion treatments, while group B (n = 22) received a synergy of five oxybrasion treatments and a mixture of phytic, pyruvic, and lactic and lactic ferulic acids at 40% pH 1.4. Cosmetic treatments were performed every 14 days, and The Derma Unit SCC3 apparatus (Courage & Khazaka, Cologne, Germany) Sebumeter SM 815 and Corneometer CM825 and GAGS scale were used to check their effectiveness.

Results

A Bonferroni post hoc test showed that group A and B did not differ from each other in acne severity before treatment (p = 1.00). However, these samples differed significantly after treatment (p < 0.001), suggesting that combined treatment of oxybrasion and cosmetic acids has a better effect than oxybrasion alone. Also, two treatment conditions (before and after) were statistically different for groups A and B separately (p < 0.001), indicating a similar efficacy of both treatments on acne severity.

Conclusion

Cosmetic treatments improved acne-prone skin and selected skin parameters. Better results were obtained by combining an oxybrasion treatment with cosmetic acids.

Clinical Trial Approval

The clinical trial with ID ISRCTN 28257448 approved this study.

A Subjective and Objective Assessment of Combined Methods of Applying Chemical Peels and Microneedling in Antiaging Treatments

Combined methods of applying chemical peels and antioxidants could be an option for skin rejuvenation with no down-time. The penetration of active substances can be enhanced by microneedle mesotherapy. The study was conducted on a group of 20 female volunteers, aged 40-65 years. All volunteers received a series of eight treatments performed every seven days. The whole face was first treated with azelaic acid; following this, the right side received a 40% solution of vitamin C and the left side 10% vitamin C with microneedling. Hydration and skin elasticity were markedly improved, with better results observed on the microneedling side. Melanin and erythema index decreased. No significant side effects were seen. The combination of active ingredients and delivery techniques have great potential to enhance the effectiveness of cosmetic preparations, probably by multidirectional ways of action. In our study, we demonstrated that both 20% azelaic acid + 40% vitamin C treatment and 20% azelaic acid + 10% vitamin C + microneedle mesotherapy efficiently improved the assessed parameters of aging skin. However, the use of microneedling mesotherapy as a means of direct delivery of active compound to the dermis enhanced the effectiveness of the studied preparation.

Subcision for Atrophic Acne Scarring: A Comprehensive Review of Surgical Instruments and Combinatorial Treatments

Subcutaneous incisionless surgery, also known as subcision, is a minimally invasive procedure that is commonly indicated for the treatment of atrophic acne scars. In recent years, many new techniques have been developed to maximize results from this procedure. This review article aims to identify an updated list of instruments and combinatorial treatments available for atrophic acne scar patients undergoing subcision. We constructed a comprehensive PubMed search term and performed triple-blinded screening on all resulting studies for mentions of subcision as indicated by acne scarring. Our results show that there are four main categories of subcision tools that are commonly employed to treat atrophic acne scars: needles, cannulas, wires, and blunt-blade instruments. Usage of these devices varies by scar depth, personal preference, and combinatorial treatment options. Overall, subcision is a particularly effective treatment for atrophic acne scars, and there is vast potential for further innovation with this technique.

Advances in Biomedical Functions of Natural Whitening Substances in the Treatment of Skin Pigmentation Diseases

Pigmentation diseases can lead to significant color differences between the affected part and the normal part, resulting in severe psychological and emotional distress among patients. The treatment of pigmentation diseases with good patient compliance is mainly in the form of topical drugs. However, conventional hydroquinone therapy contributes to several pathological conditions, such as erythema, dryness, and skin desquamation, and requires a longer treatment time to show significant results. To address these shortcomings, natural whitening substances represented by kojic acid and arbutin have gradually become the candidate ingredients of traditional local preparations due to their excellent biological safety. This review focuses on several natural whitening substances with potential therapeutic effects in pigmentation disease and their mechanisms, and a thorough discussion has been conducted into the solution methods for the challenges involved in the practical application of natural whitening substances.

Efficacy of Hydrogen Purification and Cosmetic Acids in the Treatment of Acne Vulgaris: A Preliminary Report

Acne and skin lesions that appear in its course deteriorate the quality of life of patients, cause depression and the emergence of suicidal thoughts. Cosmetic treatments can have a positive effect on improving skin condition by cleaning up skin eruptions, thus improving the well-being of affected people. Hydrogen purification is a treatment that uses alkaline water generated by a device, which reduces sebum from the surface of the epidermis. This is a novel treatment that has recently been introduced to beauty salons. On the other hand, cosmetic acids have been used for many years for treating people with acne vulgaris and give spectacular results in terms of improving the skin condition. In this study, skin condition was evaluated with a Derma Unit SSC 3 device. The Global Acne Grading System (GAGS) was used to check acne severity. Twenty-four women aged 19-21 years (M = 20.13, SD = 0.80) diagnosed with mild acne vulgaris and a high sebum level participated in the study. Group A underwent a hydrogen purification treatment using an H2jet manipulator, which ejected alkaline water from the manipulator under pressure. Group B underwent a hydrogen purification treatment with the use of a phytic, pyruvic, lactic and ferulic acids at 40% mixture (pH 1.4). A series of four treatments was performed at 14-day intervals in both groups. Skin parameters were measured before and 30 days after the series of treatment. Very good results were obtained in both groups. The skin eruptions in patients were reduced and we also observed lower amounts of sebum on the surface of the epidermis, and an improvement in skin hydration. However, in group B, the results were better than in group A. The study showed that the synergy of the treatments produced much better effects than those obtained by completing the hydrogen purification treatment alone.

Characterization and Valorization of 'Sulmona Red Garlic' Peels and Small Bulbs

'Sulmona red garlic' is an Italian variety characterized by a red tunica surrounding a white bulb. Red tunicae and non-commercial small bulbs are food wastes that must be studied for their added value. Hydroalcoholic extracts, obtained by separated inner and outer tunicae and peeled bulbs of small commercial 'Sulmona red garlic' bulbs, harvested at two different years, were first characterized with respect to their color, polyphenolic content, and antiradical activity. Then, an untargeted metabolic profile by means of electrospray ionization Fourier transform ion cyclotron resonance (ESI FT-ICR) mass spectrometry led to a comparative evaluation of the chemical diversity of six different samples. The study was completed by biological tests aiming to evaluate the associated health potential. Data on monocytes/macrophages showed good biocompatibility and a promising cytoprotective effect under oxidative stress conditions of all the extracts. At a molecular level, all the garlic extracts were able to downregulate the hydrogen peroxide-induced cyclooxygenase-2 and inducible nitric oxide synthase expression through the modulation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-ĸB) and peroxynitrite intracellular amounts, at different extents depending on the extract, the cell type, and the concentration. On the whole, data highlight an associated health potential of the extracts of this waste plant material both in terms of cytoprotection and of anti-inflammatory activity.

A Split Face Comparative Study to Evaluate the Efficacy of 40% Pyruvic Acid vs. Microdermabrasion with 40% Pyruvic Acid on Biomechanical Skin Parameters in the Treatment of Acne Vulgaris

The synergy of cosmetic acids, with their keratolytic and antibacterial properties, with the mechanical exfoliation of the epidermis brings faster and better treatment results. The aim of the study was to compare the effects of using only pyruvic acid and the synergy of microdermabrasion and chemical exfoliation. In total, 14 women diagnosed with acne took part in the study. Two areas were marked on the participants' faces: the right side (microdermabrasion treatment and a preparation containing pyruvic acid 40%) and the left side (preparation containing pyruvic acid 40%) without mechanical exfoliation. A series of four treatments was performed at 2-week intervals. Skin parameters such as stratum corneum hydration and sebum secretion were measured. Before the treatments, all patients had moderate acne according to GAGS (Min: 19, Max: 22, Md: 20), and after the treatments, it decreased to mild acne according to GAGS (Min: 13, Max: 17, Md: 140). On the right side of the face, there was a statistically significant reduction in sebum secretion in all the examined areas of the face and increase in the hydration of the stratum corneum. On the left side of the face, the differences were also observed in the decrease of sebum value and increase of hydration level; however, they were smaller than on the right side. The use of microdermabrasion in combination with pyruvic acid led to better results in the case of increased hydration and reduction of sebum secretion than using only pyruvic acid treatment.

Thermal Electron Attachment to Pyruvic Acid, Thermal Detachment from the Parent Anion, and the Electron Affinity of Pyruvic Acid

The kinetics of electron attachment to pyruvic acid (CH₃COCOOH) and thermal detachment from the resulting parent anion were measured from 300-515 K using a flowing afterglow─Langmuir probe apparatus. An adiabatic electron affinity (EA) for pyruvic acid was derived, 0.84 ± 0.02 eV. Electron attachment rate constants to pyruvic acid of 2.1 × 10^-8 and 1.2 × 10^-8 were measured at 300 and 400 K, respectively. Rate constants at higher temperatures are less well-defined due to possible contributions from attachment to zymonic open ketone, an endemic impurity in pyruvic acid. Similarly, unimolecular detachment rates are complicated by secondary proton transfer reaction of the pyruvic acid anion with pyruvic acid to yield an 87 Da anion. The possible contributions from these chemistries are considered, and in all cases the equilibrium constant between attachment and detachment remains well-defined, allowing for determination of the EA.

The immunomodulatory potential of phage therapy to treat acne: a review on bacterial lysis and immunomodulation

Background

Characterized by an inflammatory pathogenesis, acne is the most common skin disorder worldwide. Altered sebum production, abnormal proliferation of keratinocytes, and microbiota dysbiosis represented by disbalance in Cutibacterium acnes population structure, have a synergic effect on inflammation of acne-compromised skin. Although the role of C. acnes as a single factor in acne development is still under debate, it is known that skin and skin-resident immune cells recognize this bacterium and produce inflammatory markers as a result. Control of the inflammatory response is frequently the target for acne treatment, using diverse chemical or physical agents including antibiotics. However, some of these treatments have side effects that compromise patient adherence and drug safety and in the case of antibiotics, it has been reported C. acnes resistance to these molecules. Phage therapy is an alternative to treat antibiotic-resistant bacterial strains and have been recently proposed as an immunomodulatory therapy. Here, we explore this perspective about phage therapy for acne, considering the potential immunomodulatory role of phages.

Methodology

Literature review was performed using four different databases (Europe PubMed Central-ePMC, Google Scholar, PubMed, and ScienceDirect). Articles were ordered and selected according to their year of publication, number of citations, and quartile of the publishing journal.

Results

The use of lytic bacteriophages to control bacterial infections has proven its promising results, and anti-inflammatory effects have been found for some bacteriophages and phage therapy. These effects can be related to bacterial elimination or direct interaction with immune cells that result in the regulation of pro-inflammatory cytokines. Studies on C. acnes bacteriophages have investigated their lytic activity, genomic structure, and stability on different matrices. However, studies exploring the potential of immunomodulation of these bacteriophages are still scarce.

Conclusions

C. acnes bacteriophages, as well as other phages, may have direct immunomodulatory effects that are yet to be fully elucidated. To our knowledge, to the date that this review was written, there are only two studies that investigate anti-inflammatory properties for C. acnes bacteriophages. In those studies, it has been evidenced reduction of pro-inflammatory response to C. acnes inoculation in mice after bacteriophage application. Nevertheless, these studies were conducted in mice, and the interaction with the immune response was not described. Phage therapy to treat acne can be a suitable therapeutic alternative to C. acnes control, which in turn can aid to restore the skin's balance of microbiota. By controlling C. acnes colonization, C. acnes bacteriophages can reduce inflammatory reactions triggered by this bacterium.

Efficacy of Oxybrasion in the Treatment of Acne Vulgaris: A Preliminary Report

There are many cosmetic methods to reduce skin eruptions in people with acne vulgaris. As oxybrasion is a safe method of exfoliating dead epidermis, our objective was to investigate its effectiveness in young women with acne vulgaris. The Global Acne Grading System (GAGS) and Derma Unit SSC 3 device (Sebumeter SM 815, Corneometer CM 825) were used to assess acne vulgaris and skin properties. Twenty-four women aged 19–21 years (M = 19.50, SD = 0.66) with diagnosed mild acne vulgaris and a high level of sebum (more than 100 μg/cm²) participated in the study. Women on any dermatological treatment within the last 12 months and/or hormonal contraception were excluded. Probands were randomly assigned to two equal groups. Group A (experimental) was oxybrased with 0.9% sodium chloride solution simultaneously with compressed oxygen. Group B (placebo) was the group treated with non-carbonated mineral water and oxygen from the device (not pure). A series of five treatments was performed at 10-day intervals. Skin parameters were measured before and 30 days after the end of treatment. As a result, in group A (experimental), skin hydration and GAGS improved, while sebum on the epidermis was reduced. No side effects were noted. We concluded that oxybrasion is effective in women with acne and safe, as it improved skin parameters; however, further research is needed.

A Deep Learning-Based Facial Acne Classification System

Introduction

Acne is one of the most common pathologies and affects people of all ages, genders, and ethnicities. The assessment of the type and severity status of a patient with acne should be done by a dermatologist, but the ever-increasing waiting time for an examination makes the therapy not accessible as quickly and consequently less effective. This work, born from the collaboration with CHOLLEY, a Swiss company with decades of experience in the research and production of skin care products, with the aim of developing a deep learning system that, using images produced with a mobile device, could make assessments and be as effective as a dermatologist.

Methods

There are two main challenges within this task. The first is to have enough data to train a neural model. Unlike other works in the literature, it was decided not to collect a proprietary dataset, but rather to exploit the enormity of public data available in the world of face analysis. Part of Flickr-Faces-HQ (FFHQ) was re-annotated by a CHOLLEY dermatologist, producing a dataset that is sufficiently large, but still very extendable. The second challenge was to simultaneously use high-resolution images to provide the neural network with the best data quality, but at the same time to ensure that the network learned the task correctly. To prevent the network from searching for recognition patterns in some uninteresting regions of the image, a semantic segmentation model was trained to distinguish, what is a skin region possibly affected by acne and what is background and can be discarded.

Results

Filtering the re-annotated dataset through the semantic segmentation model, the trained classification model achieved a final average f1 score of 60.84% in distinguishing between acne affected and unaffected faces, result that, if compared to other techniques proposed in the literature, can be considered as state-of-the-art.

Methods for the Improvement of Acne Scars Used in Dermatology and Cosmetology: A Review

Acne vulgaris is a chronic skin disease that, depending on its course, is characterized by the occurrence of various skin eruptions such as open and closed comedones, pustules, papules, and cysts. Incorrectly selected treatment or the presence of severe acne vulgaris can lead to the formation of atrophic scars. In this review, we summarize current knowledge on acne scars and methods for their improvement. There are three types of atrophic scars: icepick, rolling, and boxcar. They are of different depths and widths and have different cross-sections. Scars can combine to form clusters. If acne scars are located on the face, they can reduce the patient’s quality of life, leading to isolation and depression. There are multiple effective modalities to treat acne scars. Ablative lasers, radiofrequency, micro-needling, and pilings with trichloroacetic acid have very good treatment results. Contemporary dermatology and cosmetology use treatments that cause minimal side effects, so the patient can return to daily functioning shortly after treatment. Proper dermatological treatment and skincare, as well as the rapid implementation of cosmetological treatments, will certainly achieve satisfactory results in reducing atrophic scars.

The Effects of Green Tea (Camellia sinensis), Bamboo Extract (Bambusa vulgaris) and Lactic Acid on Sebum Production in Young Women with Acne Vulgaris Using Sonophoresis Treatment

People struggling with acne vulgaris, not only experience skin eruptions and skin pain, but also report that their quality of life is worse compared with healthy people. This study examined, for the first time, the effect of sonophoresis on select skin parameters (sebum level) in young women suffering from acne vulgaris. The study included 60 women 19–23 years of age (M = 21.45, SD = 0.91) with mild and moderate facial acne. The inclusion criteria were 19–23 years of age, female or male gender, mild to moderate acne, no dermatological treatment within last 12 months, and no hormonal contraception (women). No men volunteered for the study, so the group was homogeneous. The patients were divided into two groups. Group A underwent a sonophoresis procedure using ultrasound and ultrasound gel combined with a green tea, bamboo extract ampule, and 5% lactic acid. Group B was the placebo group, where sonophoresis was performed using only ultrasound gel (no ampules). The members of the placebo group were told that they were undergoing sonophoresis with a green tea, bamboo extract, and 5% lactic acid ampule. Before and after the series of procedures, sebum levels were measured in the skin. Each patient underwent a series of five procedures using sonophoresis equipment at one-week intervals. Sonophoresis with green tea, bamboo extract, and 5% lactic acid contributed to the reduction of skin eruptions and sebum levels in the participants of the study (group A). The study results demonstrated that the combined use of plant preparations, lactic acid, and ultrasound had a positive effect on the skin of people suffering from acne vulgaris, including reduction of skin eruptions and sebum levels on the surface of the skin.

Microbiome and Probiotics in Acne Vulgaris—A Narrative Review

Acne vulgaris is a chronic disease characterised by the appearance of eruptions such as whiteheads, blackheads, pustules, papules, and cysts. Among factors that cause acne vulgaris are the abnormal keratinisation of the sebaceous canal, bacterial colonisation (Cutibacterium acnes), increased sebum production, genotypic factors, and hormonal disorders. Treatment is often long and tedious, and can lead to a reduction in quality of life and social isolation. The intestinal microbiota is greatly important in the formation of acne lesions. It is also responsible for the proper immunity of the organism. Acne is a disease that can be related to the condition of the digestive tract and its microbiome. Research shows that the use of probiotics may reduce skin eruptions. The probiotic supplementation and cosmetics markets are very dynamically developing. The use of internal supplementation and probiotic-containing cosmetics gives hope for the improvement of the skin condition of people with acne.

Clinical study on acupuncture treatment of gastrointestinal damp-heat acne

BACKGROUND

Acne is a common inflammatory disease of sebaceous glands, which brings extensive emotional and psychological distress to patients. Although acupuncture has certain advantages in the treatment of acne, the curative effect is not exact. The purpose of this trial is to evaluate the feasibility, preliminary efficacy, and safety of the "Spleen and Stomach Guiyuan Acupuncture Method" (SSGA) in the treatment of gastrointestinal damp-heat acne.

METHODS

The proposed protocol is planned as a randomized, assessor-blind, conventional-treatment-controlled trial to evaluate the efficacy of SSGA on gastrointestinal damp-heat acne. Seventy six gastrointestinal damp-heat acne patients will be randomly divided into 2 groups and receive SSGA or conventional acupuncture treatment. The entire study period is 12 weeks, including an 8-week treatment period and a 4-week follow-up period. All patients will receive 16 sessions of acupuncture treatment over 8 weeks. The primary outcome is the investigation global assessment (IGA) at week 8, which is an overall assessment of the degree of the inflammatory and non-inflammatory lesion. The secondary outcomes include IGA, the total facial lesion count (Total Lesion Count), the acne-specific quality of life, etc at weeks 8 and 12. The Expectation and Credibility of treatment rating scale will be used to measure the patients' attitudes to acupuncture after the first treatment. Adverse events will also be recorded.

DISCUSSION

This study is helpful to evaluate the feasibility, preliminary efficacy, and safety of SSGA in the treatment of gastrointestinal damp-heat acne. The results will be used in sample size calculations for subsequent large-scale studies.Trial registration: Chinese Clinical Trial Registry ChiCTR2100047363. Registered on June 13, 2021.

Effects of Topical Hydrogen Purification on Skin Parameters and Acne Vulgaris in Adult Women

BACKGROUND

Acne vulgaris is a prevalent dermatological disease characterized by skin eruptions, which may decrease the sufferer's quality of life. Hydrogen purification treatment is a new procedure used in cosmetology to improve the skin parameters of the face. This study examined the effectiveness of hydrogen purification treatment to improve women's skin conditions with regard to acne vulgaris.

METHODS

In this study, 30 women participated who suffered from a high level of sebum and acne. The control group was comprised of 30 healthy women with a low level of sebum. The Hellgren-Vincent Scale and Derma Unit SSC 3 device were used to assess acne vulgaris severity and skin properties, respectively. Four hydrogen purification sessions were carried out at 7-day intervals, using the Hebe Hydrogenium+ generating alkaline water.

RESULTS

At baseline and 7 and 14 days after finishing the series of treatments, the levels of oiliness, moisture, and skin pH were tested. The main effects of treatment were significant in the following parameters: pH around the bottom lip, moisture between the eyebrows and around the nose, and oily skin in all three face sites.

CONCLUSIONS

The level of sebum decreased and moisture levels increased during hydrogen purification. Topical hydrogen purification is an effective and safe treatment for acne vulgaris.

Association between Satisfaction with Life and Personality Types A and D in Young Women with Acne Vulgaris

People with acne vulgaris report a lower level of satisfaction with life and are more frequently classified as having Type D personalities than those without acne. This research examined, for the first time, the moderating and mediating role of personality type in the relationship between acne severity and satisfaction with life. Among 300 female nursing and cosmetology students ranging in age from 19 to 24 years (M = 21.28, SD = 1.39), 150 individuals (50%) presented with symptoms of acne vulgaris (AV group), while the other 150 (50%) were categorized as controls without acne vulgaris (WAV sample). A cross-sectional study was conducted using three self-report questionnaires: The Satisfaction with Life Scale (SWLS), the Framingham Type A Scale (FTAS), and the Type D Scale (DS14). Acne vulgaris was clinically diagnosed using the Hellgren–Vincent Scale (HVS). The AV group scored significantly higher on the FTAS and DS14 and lower on the SWLS than the WAV sample. Life satisfaction correlated negatively with both the negative affectivity (NA) and social inhibition (SI) subscales of the DS14. The moderating role of the Type A behavioral pattern (TABP) and the mediating role of both NA and SI subscales of the DS14 were observed in the relationship between acne severity and satisfaction with life. The type of personality may explain the mechanism of the relationship between acne disease and subjective well-being. Therefore, psychological interventions and strategies focused on managing stress and mood may effectively improve satisfaction with life in people with acne.
