Treatments of Periorbital Hyperpigmentation: A Systematic Review

Platelet-Rich Plasma Injection Combined With Q-Switched Ruby Laser in the Treatment of Periorbital Hyperpigmentation

BACKGROUND

Periorbital hyperpigmentation is a prevalent skin condition that represents a large quantity of cases seen in cosmetic dermatology. Patients tend to be left with pigmentation after Q-switched ruby laser treatment, especially the perioribital area.

AIMS

The study is conducted to compare the effect of PRP injection combined with laser therapy versus laser alone for periorbital hyperpigmentation treatment.

PATIENTS/METHODS

In this single-center, case-control study, 30 patients with periorbital hyperpigmentation were allocated to receive PRP injection injection after Q-switched ruby laser or Q-switched ruby laser only, followed by a 12-week and 24-week follow-up visit. Visual analogue scale, Sadick tear trough rating scale, and patients' self-evaluation were used to evaluate the therapeutic effect.

RESULTS

The combined group achieved a better improvement in long-term effect and had effect on facial rejuvenation. Patient satisfaction was higher in the combined group. Erythema and mild pain were the most common adverse reactions of both groups.

CONCLUSIONS

Combining with PRP injection can improve the therapeutic effect of Q-switched ruby laser in treating periorbital hyperpigmentation and lessen the risk of post-inflammatory hyperpigmentation, indicating a new option for POH treatment.

Biomedical applications of tyrosinases and tyrosinase inhibitors

Tyrosinase is involved in several human diseases, among which hypopigmentation and depigmentation conditions (vitiligo, idiopathic guttate hypomelanosis, pityriasis versicolor, pityriasis alba) and hyperpigmentations (melasma, lentigines, post-inflammatory and periorbital hyperpigmentation, cervical idiopathic poikiloderma and acanthosis nigricans). There are increasing evidences that tyrosinase plays a relevant role in the formation and progression of melanoma, a difficult to treat skin tumor. Hydroquinone, azelaic acid and tretinoin (all-trans-retinoic acid) are clinically used in the management of some hyperpigmentations, whereas many novel chemotypes acting as tyrosinase inhibitors with potential antimelanoma action are being investigated. Kojic acid, hydroquinone, its glycosylated derivative arbutin, or the resorcinol derivative rucinol are used in cosmesis in creams as skin whitening agents, whereas no antimelanoma tyrosinase inhibitor reached clinical trials so far, although thiamidol is a recently approved new tyrosinase inhibitor for the treatment of melasma. Kojic acid and vitamin C are used for avoiding vegetable/food oxidative browning due to the tyrosinase-catalyzed reactions, whereas bacterial enzymes show potential in biotechnological applications, for the production of mixed melanins, for protein cross-linking reactions, for producing phenol(s) biosensors, of for the production of L-DOPA, an anti-Parkinson's disease drug.

Evaluation of the effectiveness of picosecond KTP and fractional thulium lasers on pigmented-type periorbital dark circles

OBJECTIVE

To determine the effectiveness of picosecond KTP in reducing peri-ocular dark circles caused mainly by excessive pigmentation and to compare Picosecond KTP with Thulium laser ability in reducing the intensity and extent of peri-ocular dark circles.

MATERIALS AND METHODS

This split-face prospective study included twelve women with periorbital dark circles (pigmented or mixed-pigmented type). The left lower eyelid was treated using the PicoHi machine (HIRONIC Ltd), a full beam Q-switched Nd-YAG provided by KTP crystal (523 nm) at settings of 0.3 J/cm2, 5 mm, 5 Hz, and 300 Ps. Whereas the right lower eyelid was treated using the Lavieen machine (WON TECH Co., Ltd), a fractional Thulium laser (1927 nm) at setting 1320 mJ/cm2, 30 × 15 mm, 1500 microseconds. Patients received a series of 3 treatment sessions, given at 4-week intervals.

RESULTS

The 532-nm full beam Q-switched KTP and fractional Thulium lasers were more likely to induce post-inflammatory hyperpigmentation rather than decrease the pigmentation. The risk is higher with a Q-switched KTP laser, which may be attributed to the skin tone of the participants. Nonetheless, some improvement in the pigmented type of PDCs, although not detected clinically, was documented by the VISIA software.

CONCLUSION

No solid conclusion can be drawn from the results of the study. Picosecond KTP and Thulium lasers may have a role in reducing PDCs yet more studies should be performed in order to determine the exact impact these lasers have.

Interventional and device treatment of the periocular area

Growth in the research, innovation, and development of laser and energy-based technologies over the past few decades has led to dramatic increases in treatment options for dermatologic and cosmetic concerns of the periorbital area. We highlight recent treatment options using laser and energy-based devices for the clearance of periocular pigmented lesions, including solar lentigines and nevus of Ota; vascular lesions, including port-wine birthmarks, infantile hemangiomas, superficial telangiectasias, and reticular veins; laser ablation of benign tumors, such as xanthelasma; cosmetic rejuvenation; treatment of infraorbital dark circles and festoons; laser removal of eyebrow and eyeliner tattoos; and device-based treatment of chronic dry eyes.

Electrical stimulation of the lower eyelid orbicularis oculi muscle improves periocular dark circles

BACKGROUND

We developed and tested the safety and efficacy of a cosmetic device to improve dark circles using electrical muscle stimulation of the orbicularis oculi muscle.

METHODS

Overall, 18 participants (36 eyes) were studied. The following five items were evaluated before and after the intervention:(1) the Clinical Dark Circle Score using clinical findings and photographs, (2) transcutaneous oxygen partial pressure (TcPO2) on the lower eyelid, (3) thermography, (4) two-dimensional laser blood flowmetry, and (5) spectrophotometry.

RESULTS

The mean score at baseline was 2.0 ± 0.90 (mean ± standard deviation), and that at the end of the study was 1.2 ± 1.0 (Wilcoxon signed-rank sum test, p < 0.0001), indicating a significant reduction. The spectrophotometer showed a significant decrease in a* and L* values before and after use (Wilcoxon signed-rank sum test, p < 0.0001). There was also a weak negative correlation between the change in score and the change in blood flow and TcPO2 measured using a laser perfusion device (Spearman's rank correlation coefficient, r = -0.32 and -0.39, respectively). Stratified analysis of the baseline score showed a strong negative correlation between the change in score and the change in spectrophotometric a* in the subjects/group with mild periocular dark circles (Spearman's rank correlation coefficient, r = -0.46). Contrastingly, no correlation was observed for any of the measurements in the subjects/group with severe periocular dark circles. After 1 month, no device-related ophthalmic adverse events were observed in any of the participants.

CONCLUSION

Electrical muscle stimulation could improve periocular dark circles, especially in the subjects/group with mild periocular dark circles, and was safe.

Efficacy of castor oil cream in treating infraorbital hyperpigmentation: An exploratory single-arm clinical trial

INTRODUCTION

Infraorbital hyperpigmentation represents one of the most prevalent conditions in cosmetic dermatology. To treat this condition, many patients prefer natural remedies. This study explored the efficacy of topical castor oil cream in treating patients with infraorbital hyperpigmentation.

METHODS

We conducted an exploratory single-arm clinical trial at the Shahid Faghihi Dermatology Clinic and Molecular Dermatology Research Center of Shiraz University of Medical Sciences, Shiraz, Iran, during 2021-2022. Using the convenience sampling method, we enrolled 25 patients with infraorbital hyperpigmentation. We instructed the patients to apply topical castor oil cream twice daily for 2 months. The darkness, melanin, and erythema levels were evaluated by VisioFace® 1000 D and SkinColorCatch® devices. We used a visual analog scale to assess skin laxity, wrinkles, and patient satisfaction. Data analysis was done with Stata version 14.2.

RESULTS

The data of 22 patients with a mean age of 40.92 ± 7.33 years were analyzed. The VisioFace® scores decreased significantly by the end of the study [right eyes: mean difference (MD): -5.63 (95% CI: -7.12 to -4.15), p < 0.001; left eyes: MD: -5.91 (95% CI: -7.46 to -4.36), p < 0.001]. Moreover, castor oil cream significantly reduced the melanin level, wrinkles, and skin laxity in the infraorbital region (p < 0.05).

CONCLUSIONS

Castor oil cream seems to be an effective alternative for treating infraorbital hyperpigmentation. Randomized clinical trials are needed to confirm our findings.

Effectiveness, safety, and patient satisfaction of carboxytherapy as an adjunctive treatment for periorbital hyperpigmentation

INTRODUCTION

Dark under-eye circles or periorbital hyperpigmentation constitute a prevalent and challenging cosmetic problem with diverse etiologies and types. While modifying exacerbating habits can provide partial relief for the pigmentary and vascular factors associated with this condition, and despite the abundance of available treatment options, there is currently a lack of gold-standard evidence-based treatments proposed for curing this disorder.

OBJECTIVES

This study aimed to assess the safety and effectiveness of carboxytherapy in treating periorbital hyperpigmentation.

MATERIAL AND METHODS

In this 4-week single-arm clinical trial, 20 eligible Iranian patients with symmetric periorbital hyperpigmentation received weekly intradermal carboxytherapy. The treatment involved administering 10-20 mL of CO2 at a rate of 20 mL/min and a temperature of 15°C for a duration ranging from a few seconds to 1 min. Follow-up assessments were conducted 1 month after the final session. The primary outcome was defined as the changes in ΔE or the variations in pigmentation observed between the orbital and extra-orbital skin before and after the trial.

RESULTS

The patients reported satisfaction with the statistically significant reduction in hyperpigmentation achieved through carboxytherapy in the lateral (p = 0.002), middle (p = 0.001), and medial (p = 0.001) regions of the periorbital area. The total response rate of the patients was estimated at 20%. Patient satisfaction exceeded ΔE changes, with no significant linear relationship (p = 0.084).

CONCLUSION

Carboxytherapy can be proposed as an effective and safe treatment for periorbital hyperpigmentation.

Effectiveness and tolerance of multicorrective topical treatment for infraorbital dark circles and puffiness

BACKGROUND

Treatment of infraorbital dark circles and under-eye puffiness is challenging due to its multifactorial nature and lack of broadly applicable, effective treatments. A daily skincare treatment option that is multimodal, effective, and tolerable across a broad patient population is an unmet need.

AIM

A multicorrective topical eye cream (MTEC) formulated with Tetrahexyldecyl (THD) ascorbate (vitamin C), prebiotic Inula Helenium, bioavailable peptides, botanical extracts, chrysin, and caffeine is hypothesized to improve the appearance of infraorbital dark circles and under-eye puffiness by targeting microvasculature congestion and permeability, melanin accumulation and hemoglobin degradation-related pigmentation, and skin health.

METHODS

An IRB approved, open-label, 12-week clinical study set out to evaluate the efficacy and tolerability of the MTEC across a broad patient population including varying ethnicities and Fitzpatrick Skin Types (FST). Female subjects (n = 40) ages 35-60 years old, with moderate-to-severe under-eye dark circles, moderate under-eye puffiness, and mild-to-moderate fine lines were enrolled into the study. Objective (Chromameter, VISIA® imaging, and Laser Doppler) and subjective assessments (clinical grading and self-assessment questionnaire) were conducted at baseline and post-baseline timepoints.

RESULTS

Thirty-seven subjects completed the study, and the MTEC efficaciously demonstrated short-term and long-term improvements in objective and subjective assessments across a broad patient population. Specifically, the MTEC demonstrated significant improvement of infraorbital dark circles, mainly by the reduction in microvasculature congestion and permeability, melanin, and hemoglobin degradation-related pigmentation.

CONCLUSION

Topical application of the MTEC may offer an effective and tolerable treatment option for infraorbital dark circles and puffiness.

Treatment of periorbital hyperpigmentation using light devices

The treatment of dark circles is one of the most common request from the patients attending to the esthetics clinic. A tired, sad or aged appearance is perceived by our patients. Moreover, it is a multifactorial problem and we could treat it with a wide range of treatments. With this systematic review, we want to check the best available evidence regarding the treatment of periorbital hyperpigmentation using light devices. We have reviewed 208 papers, including 14 of them for full consideration. Several light sources have demonstrated to be effective treating pigmented dark circles. The best results have been reported using intense pulsed light and rubi laser together with depigmenting substances. If we want to treat periocular hyperpigmentation, soft wrinkles, rhytides and skin density we should use carbo dioxide laser or Erbium:Yttrium Scandium Gallium Garnet. The Neodymium-Doped Yttrium Aluminium Garnet, alexandrite and diode lasers were the ones giving the worst outcome regarding pigmentation treatment. The concomitant use of depigmenting treatment may help getting better results and reducing the rate of post inflammatory hyperpigmentation. A better standardization and measuring of the obtained results is needed regarding pigmentation changes. We must keep on investigating on this topic with new clinical trials measuring objective results and combining different light devices for a multifactorial treatment of the dark circles.

Tetrahedral framework nucleic acid loaded with glabridin: A transdermal delivery system applicated to anti-hyperpigmentation

Topical application of tyrosinase inhibitors, such as hydroquinone and arbutin, is the most common clinical treatment for hyperpigmentation. Glabridin (Gla) is a natural isoflavone that inhibits tyrosinase activity, free radical scavenging, and antioxidation. However, its water solubility is poor, and it cannot pass through the human skin barrier alone. Tetrahedral framework nucleic acid (tFNA), a new type of DNA biomaterial, can penetrate cells and tissues and can be used as carriers to deliver small-molecule drugs, polypeptides, and oligonucleotides. This study aimed to develop a compound drug system using tFNA as the carrier to transport Gla and deliver it through the skin to treat pigmentation. Furthermore, we aimed to explore whether tFNA-Gla can effectively alleviate the hyperpigmentation caused by increased melanin production and determine whether tFNA-Gla exerts substantial synergistic effects during treatment. Our results showed that the developed system successfully treated pigmentation by inhibiting regulatory proteins related to melanin production. Furthermore, our findings showed that the system was effective in treating epidermal and superficial dermal diseases. The tFNA-based transdermal drug delivery system can thus develop into novel, effective options for non-invasive drug delivery through the skin barrier.

Disorders of Facial Hyperpigmentation

Disorders of hyperpigmentation are common and challenging conditions which can arise due to a myriad of etiologic factors. Many of them can present across skin types but are more common in skin of color individuals with Fitzpatrick skin types III-VI. Facial hyperpigmentation, in particular, can have a significant impact on the quality of life of affected individuals due to its increased visibility. This article provides a comprehensive review of disorders of facial hyperpigmentation including epidemiology, pathogenesis, diagnostic considerations, and treatment approaches for these conditions.

Modern blepharoplasty: From bench to bedside

The demand for procedures aiming to rejuvenate the upper third part of the face and the periocular region has increased in the past several years. Blepharoplasty is one of the most frequently performed procedures worldwide to date. Surgery is currently the first choice in order to achieve permanent and effective results; however, it is burdened by potential surgical complications feared by patients. There is an increasing trend in individuals to request less invasive, non-surgical, effective, and safe procedures for eyelid treatment. The aim of this minireview is to present a brief overview of non-surgical blepharoplasty techniques that have been reported in the literature in the past 10 years. Numerous modern techniques that provide a rejuvenation of the entire area have been described. Numerous less invasive methods have been proposed in the current literature and in modern-day routine clinical settings. Dermal fillers are a commonly chosen option for providing enhanced aesthetic results, especially considering that volume loss can be one of the main underlying causes of facial and periorbital aging. Deoxycholic acid use may be considered when the problem is represented by periorbital excess fat deposits. The simultaneous excess and loss of elasticity of the skin can be assessed with techniques such as lasers and plasma exeresis. Furthermore, techniques such as platelet-rich plasma injections and the insertion of twisted polydioxanone threads are emerging as viable methods to rejuvenate the periorbital region.

Optical characteristics of the skin with dark circles using pump-probe imaging

Pump-probe imaging was first used for quantitative analysis of melanin in dark circles' skin to improve the ability to diagnose and treat dark circles on human skin. This study aimed to compare the distribution characteristics in melanin of lower eyelid skin tissues and to determine whether pump-probe imaging has potential for the classification of dark circles in vivo. Specimens obtained from 15 patients undergoing blepharoplasty were examined using pump-probe imaging. Furthermore, adjacent slices were respectively treated with hematoxylin-eosin (HE) and ferrous sulfate (FeSO₄) staining for cross-references. Subsequently, the melanin content index (MCI) and mean fluorescence intensity (MFI) were quantitatively analyzed by the pump-probe imaging. The distribution of melanin granules in the pump-probe image and FeSO₄ staining was consistent. Meanwhile, the tissues of the skin with dark circles and normal skin demonstrated significant differences in MCI and MFI. These differences can be used to distinguish the skin with dark circles from the normal skin. Pump-probe imaging could be used for the analysis of the microstructure and spectral characteristics of melanin granules in skin with dark circles. Significant differences were noted between the pigmented type of dark circles and the other two groups (normal skin and the vascular type of dark circles), while no significant differences were found between normal skin and the vascular type of dark circles.

Global Research Trends and Perspectives of Blepharoplasty: A 20-Year Bibliometric Analysis Based on Web of Science

BACKGROUND

The number of publications on blepharoplasty is increasing rapidly. Bibliometric analysis can help surgeons quickly and systematically understand the current state of development. To our knowledge, there are no bibliometric studies on blepharoplasty, and therefore, we conducted this study to reveal research trends and perspectives of blepharoplasty.

METHODS

Relevant publications from 2002 to 2021 were extracted from the Web of Science Core Collection database. After manual screening, VOSviewer software and CiteSpace software were used to collect and analyze the acquired data.

RESULTS

A total of 1125 publications were included and the publications per year increased annually. Contributions from the USA led both quantity and quality. The University of California System was one of the most influential academic institutions. Aesthetic Plastic Surgery had the most publications, and Plastic and Reconstructive Surgery was the most frequently cited or co-cited journal. Massry GG and Hamra ST were the most prolific and co-cited authors, respectively. Additionally, Rohrich RJ had the highest number of citations per publication. References co-cited analysis identified that lower eyelid research was a hotspot. Keywords were mainly divided into 6 clusters, namely "lower lid blepharoplasty," "complications," "facial rejuvenation," "blepharoptosis," "upper blepharoplasty," and "Asian blepharoplasty and epicanthoplasty."

CONCLUSIONS

Blepharoplasty research is flourishing, and three clusters may be the hotspots: "Lower blepharoplasty and mid-face rejuvenation," "overall facial outcome and quality-of-life," and "Asian blepharoplasty and epicanthoplasty."

Evaluation of Efficacy and Safety of Low-Fluence Q-Switched 1064-nm Laser in Infra-orbital Hyperpigmentation Based on Biometric Parameters

Introduction: Dark circles and wrinkles under the eyes are common cosmetic problems, caused by various conditions, especially aging and overproduction of melanin in the epidermis or dermis of the skin. Iin addition to the application of topical lightening agents, different types of lasers, especially the Q-Switched ND:YAG laser, have been used for the treatment of cutaneous hyperpigmentation. Because of a high prevalence of idiopathic eye dark circles (EDCs) or periorbital melanosis and a poor response to available therapies, we decided to evaluate the efficacy and safety of the Fractional QS 1064 nm ND:YAG Laser through a before-after trial. Methods: 18-65-year-old patients with skin Fitzpatrick phototype of I-V and without any usage of a topical or systemic therapeutic regimen (2-4 weeks before the trial) were enrolled in the study. Each patient was treated with 6 sessions of the Fractional QS 1064 nm ND:YAG Laser at 2-week intervals and assessed for response and possible side effects or recurrences through 4 outcome measures, including Visoface-based color and erythema, melanin index and lightness (Before the fourth and sixth sessions of the therapy; also 1 week and 3 months after finishing the trial). Results: The changes of Visoface-based color and erythema, the melanin pigment amount by the Mexameter (melanin index) and the degree of lightness by the Colorimeter of patients after 6 months of intervention were statistically significant (P<0.001). Conclusion: The fractional QS 1,064 nm ND:YAG Laser is an effective and safe therapy in EDCs since objective outcomes like the reduction of the melanin index and improving lightness and subjective ones like the reduction of darkness and erythema were confirmed.

A randomized comparative study of the effect of two different flow rates of carboxytherapy in the treatment of infraorbital dark circles

BACKGROUND

Carboxytherapy is a minimally invasive, relatively safe modality that has been used for the treatment of dark circles; however, different flow rates and different injection techniques have been described in the literature.

AIM

To study the effect of the flow rate on the therapeutic outcome of carboxytherapy in infraorbital dark circles.

METHODS

Eighty patients with infraorbital dark circles were divided into two equal groups: Group A received carboxytherapy at a flow rate of 30 ml/min, and group B received carboxytherapy at a flow rate of 60 ml/min. Patients received weekly sessions for 6 weeks, and the treatment response was evaluated 6 weeks after the last treatment session.

RESULTS

Significant improvement of the dark circles was detected in both treatment groups. However, no significant difference in the treatment response was found when both flow rates were compared. The frequency of development of side effects was significantly higher in the group receiving CO₂ at a flow rate of 60 ml/min. No significant difference in the overall post-treatment patient satisfaction between the two groups was detected.

CONCLUSION

Carboxytherapy is an effective therapeutic modality for infraorbital dark circles. Lower flow rates achieve therapeutic responses similar to higher flow rates but with fewer side effects.

Periorbital Hyperpigmentation—Dark Circles under the Eyes; Treatment Suggestions and Combining Procedures

Periorbital hyperpigmentation (POH) is a frequent concern among both young and adult patients. The etiology is multifactorial with a genetic background. Prevalence is higher in darker skin types. It has been estimated as high as 30% in a recent Indian study. Females are often more disappointed by POH than males. Treatment has to consider underlying pathologies and patients’ needs. We present our treatment algorithm for POH. In this study, 74 patients with POH, 64 females (86.5%) and 10 males (13.3%), were treated. Of these, 39 patients (53%) had a family history of POH. The age range of patients was 18−57 years (average: 36.1 years). In case of tear trough deformity, soft tissue augmentation was used by injection of hyaluronic acid gel, calcium hydroxylapatite, or autologous fat. Blepharoplasty with partial fat pad resection or repositioning via arcus marginalis release was used to correct severe orbital fat herniation and excess of the lower lid skin. Melanin hyperpigmentation of the skin was improved by sessions of Q-switched 1064 and 532 nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. Small vessels (capillaries and veins) were targeted by a 1064 nm long-pulsed Nd-YAG laser. Sessions of intense pulsed light (IPL) or CO2 fractional laser were employed to improve skin texture and fine lines. Topical hyaluronic acid-based formulations may be used as adjuvant self-treatment by patients. For pigmented and mixed-type POH, ultraviolet light protection is recommended as a maintenance treatment. By the use of various technologies, treatment can be individually tailored.
