Skin whitening is a practice that is used to obtain lighter skin tone and is most prevalent in Africa and Asia. Substances used for this procedure, such as hydroquinone or mercury have a variety of side effects and are banned in several countries. This study examined the popularity of internet searches for terms related to skin whitening and bleaching creams with the use of GoogleTrends (GT). GT was searched globally for the topic "skin whitening" and two terms "hydroquinone cream" and "mercury cream" throughout a 10-year period (01.09.2013-31.08.2023). The popularity of searches increased during the analyzed period. The topic "skin whitening" was most popular in Sudan, Vietnam, and Sri Lanka. The searches were higher for "hydroquinone cream" than "mercury cream" in almost all countries, besides the Philippines and Indonesia. Our study confirms that skin whitening practices are popular, especially among populations with darker skin tone. Despite potentially toxic side effects, creams with hydroquinone and mercury are increasingly searched worldwide. Education about skin whitening and the usage of bleaching substances should be implemented, especially in the regions of Africa and Asia.

Laser hair removal is a commonly used method in dermatology which is based on selective thermolysis and utilizes the appropriate wavelength, pulse width, and energy density to damage hair follicles. Given the prevalence of skin diseases such as psoriasis, dermatitis, and vitiligo, and the increasing popularity of laser hair removal, the aim of this study was to investigate the safety of laser hair removal in individuals with skin diseases. This retrospective study was conducted at the laser department of Razi Hospital on 99 patients who underwent laser hair removal. The exacerbation of disease after laser therapy was significantly associated with active skin disease (p = .021) and laser treatment at the site of the disease (p < .001). The incidence of Koebner phenomenon was significantly associated with age (p = .017) and the number of sessions with the ND-YAG device (p = .034). It is crucial to exercise caution when performing laser treatment on individuals with active skin disease and to avoid treating the affected area were possible. If necessary, it is recommended to delay laser treatment until the disease is under control for patients with active skin disease or those who wish to receive laser treatment at the site of the disease.

Photopneumatic therapy (PPT) combines vacuum and pulsed, broadband light to extract debris and bacteria from the pilosebaceous units; monotherapy is unexplored. Facial acne lesions and skin texture were evaluated after up to six PPT treatments, 1-2 weeks apart for 15-20 minutes per treatment using customized energy settings, in seven female patients with inflammatory, comedonal and pustular lesions. Lesion and redness reduction with improvement in skin texture and pore size were observed after 1-3 treatments; adverse effects were infrequent. PPT may optimize lesion clearance as monotherapy and/or as an adjuvant. The ability to change pulse structure, pulse duration, vacuum pressure and fluence allow for treatment that best matches skin type and acne severity.

Reed Syndrome, or hereditary leiomyomatosis and renal cell carcinoma syndrome, is a rare, autosomal dominant genetic condition that predisposes individuals to a triad of cutaneous leiomyomas, uterine leiomyomas and renal cell carcinoma. Cutaneous leiomyomas are often the first manifestation of the syndrome, occurring in 76% of patients and average 26 in number. We present a case of a 47 year old female with Reed Syndrome with an unusually extensive cutaneous burden, with a total of 361 cutaneous lesions, far above the average reported number of 26. Due to the extent of her cutaneous burden, painful nature of the lesions and failure to respond to standard therapies, she was referred for fully ablative Erbium:Yag laser resurfacing therapy. The use of fully ablative Erbium:YAG laser resurfacing therapy for treatment of cutaneous leiomyomas has not been reported in the literature to date. One year following laser therapy, the treatment area not only began to repigment, but there was also no evidence of cutaneous leiomyomas recurrence or associated pain. Given the effectiveness of this unique therapy, fully ablative Erbium:YAG laser resurfacing should be kept in mind as a treatment option for both cosmetic and symptomatic cutaneous leiomyomas.

Microneedle fractional radiofrequency (MFRF) has been used to improve photoaging and scars. This study aimed to evaluate the efficacy and safety of MFRF with basic fibroblast growth factor (bFGF) for facial atrophic acne scars and skin rejuvenation by blinded visual evaluation, self-report, and reflective confocal microscopy (RCM). Fifteen subjects were randomized to the MFRF with bFGF group and fifteen to the MFRF group. All subjects underwent three-session therapy and a follow-up period. Significant group differences were in ECCA, global improvement score, satisfaction, and downtime before and after treatment. Combination therapy could be more effective than monotherapy for acne scars and facial rejuvenation. In addition, RCM can be used to observe the changes in skin collagen before and after treatment in evaluating cosmetic efficacy.

Various topical interventions have been described to minimize botulinum neurotoxin-A (BoNT)-induced pain. The purpose of this study is to conduct a systematic review of relevant randomized controlled trials (RCTs) to compare the efficacy of pain relief methods during BoNT injection. PubMed, Scopus, and Web of Science were searched using "Botox," "Botulinum," or "BTX." We identified RCTs in which BoNT were injected to eliminate wrinkles. The pain score was the study outcome, and pain reduction method was compared with routine one. The meta-analysis was reported using the PRISMA checklist. The Higgins I(I²) statistical model assessed results heterogeneity. Two thousand one hundred and twenty-three articles were identified, thirteen articles eligible. Two hundred and sixty-two healthy volunteers were performed on these RCTs. Meta-analysis evaluated different methods to ease BoNT injection pain, and these methods significantly improved outcomes by 0.23% (95%CI, 0.11-0.46, p = .000). Subgroup analysis based on injection area showed no significant heterogeneity, but heterogeneity decreased when subgroup analysis based on other methods was done (Cochran's Q test = 115.52, p = .0001, I² = 87.9%). This meta-analysis confirms the effectiveness of pain relief methods during BoNT injection. Evaluation of different methods showed their effectiveness, but finding the best method requires comparative studies, although the role of pH and EMLA has been proven.

Contemporary approaches for facial rejuvenation encompass the utilization of both ablative and nonablative laser techniques. Extensive research has elucidated the adverse consequences associated with ablative laser treatment, such as the emergence of infectious, follicular, scarring, and pigmentary alterations. Nonablative fractional lasers exhibit commendable cosmetic outcomes, characterized by a diminished incidence of complications owing to their photomechanical mechanisms, in contrast to ablative laser modalities. Nonetheless, it is imperative to acknowledge that untoward effects may still manifest. In this report, we present two cases of herpes simplex virus (HSV) reactivation subsequent to nonablative fractional resurfacing. Timely identification and the appropriate administration of antiviral agents are important, which serve as imperative measures to mitigate the long-term consequences that may arise in the event of complications.

We aimed to determine the efficacy of the various available oral, topical, and procedural treatment options for hair loss in individuals with androgenic alopecia. Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic review of the National Library of Medicine was performed. Overall, 141 unique studies met our inclusion criteria. We demonstrate that many over the counter (e.g. topical minoxidil, supplements, low-level light treatment), prescription (e.g. oral minoxidil, finasteride, dutasteride), and procedural (e.g. platelet-rich plasma, fractionated lasers, hair transplantation) treatments successfully promote hair growth, highlighting the superiority of a multifaceted and individualized approach to management.

We compared the effectiveness and safety of the long-pulsed neodymium-doped yttrium-aluminum-garnet (Nd:YAG) laser alone and combined with a 755-nm alexandrite laser for treating palmoplantar warts. We divided patients into two groups to receive up to four monthly treatments with Nd:YAG alone (single-wavelength) or combined with the alexandrite laser (dual-wavelength). We assessed treatment responses (according to clearance rate), vascular/hyperkeratosis grades, and patient satisfaction and pain ratings. The differences in treatment response (p = .348), patient satisfaction (p = .560), and pain ratings (p = .728) between the groups were not significant. The single- and dual-wavelength treatment options were equally effective in treating recalcitrant palmoplantar warts.

Facial and neckline telangiectasias have an underestimated yet important impact on quality of life of patients with systemic scleroderma (SSc). This monocentric, prospective, open-label, intra-patient comparative study was conducted in 21 consecutive patients with SSc. Patients underwent 4 sessions of PDL 8 weeks apart. A final quadruple assessment was performed by several raters 2 months after the last session, based on the following criteria: change in telangiectasia number; subjective improvement score (LINKERT scale); impact on the quality of life (QoL; SKINDEX score); visual analog pain scale; adverse effects (AEs), including treatment discontinuation for PDL-induced purpura and patient satisfaction. The mean telangiectasia number decreased by 5 (32%) at the end of the protocol. Eighteen patients (85.7%) reported an improvement or a strong improvement, versus 73.81% for the expert committee. Immediate session pain (mean = 3.4/10) was slightly less than overall pain (mean = 4.6/10). Ten patients (47%) experienced at least one AE (oozing/crusts, edema, epidermal blistering), including PDL-induced purpura in 3 patients (14%). AEs were mostly transient (<1 week) and mild (CTCAE grade 1). All QoL parameters improved after treatment, and 85% of patients were satisfied.
