BACKGROUND: Laser hair removal is an increasingly prevalent trend of cosmetic procedures. The purpose of this study was to assess the effectiveness of hair reduction among several types of laser interventions. METHODS: The selected studies searched in PubMed and EMBASE were assessed for quality of evidence, and extracted data on absolute hair count and hair reduction rate. Qualitative data were synthesized using standardized mean difference (SMD) in frequentist network meta-analysis because various measurement units were used among selected studies...

The goal was to determine ways to optimize diagnostic and therapeutic measures for various types of melasma in the outpatient setting of the dermatovenerological ambulatory clinic. The study involved 112 women with a confirmed diagnosis of facial melasma whose disease lasted for at least 2 years. The severity of patient pigmentation was evaluated using the Melasma Area Severity Index and the Melasma Severity Scale. There was a significant increase in melanin levels across all melasma types, an increase in erythema in the dermal type, and an increase in sebum production in the epidermal type...

The lack of uniform and objective techniques to evaluate treatment efficacy in photo-epilation studies leads to contradictory results. Thus, there is an urgent need to explore commonly accepted assessment tools. One of the most common methods uses hair counts via digital photography. However, macrophotography may not be able to depict the vellus-like hair induced by photo-epilation. On the other hand, handheld dermatoscopy is practical, affordable and offers high-quality magnification. Hair counts from a handheld dermatoscope and a digital camera were compared in 73 women who underwent 6 sessions with the Alexandrite 755 nm laser...

Patterned hair loss is a common type of non-scarring alopecia, characterized by miniaturization of hair follicles. The etiology of female pattern hair loss (FPHL) is not clearly linked to androgens or other hormones thereby making it a challenging condition to treat. Various treatment modalities, like minoxidil (topical or oral), spironolactone, finasteride, have been tried alone or in combination with variable results. Combination therapy is superior to the monotherapy, since these multiple treatment modalities act by targeting different pathogenetic pathways, making the treatment aggressive and more effective...

Port-wine stains (PWS) are frequently refractory to laser treatments. The aim of this study is to evaluate the role of treatment interval time. From 1990, 216 patients underwent Pulsed Dye Laser sessions. The laser sessions were scheduled at a minimum interval of 4 weeks to a maximum of 48 weeks. Clinical outcomes were assessed 8 weeks after the last laser session. Better results were obtained with 8 weeks interval time between therapy session, and high efficacies were also found for intervals of 4, 6 and 10 weeks...

OBJECTIVE: to report a possibly novel complication of laser hair removal. CASE REPORT: a white-skinned 18-year-old patient discovered an umbilical, brown, and raised lesion while shaving before his second diode laser hair removal session. He sought consultation before his fourth laser session since the lesion further thickened and darkened. Dermoscopy showed no pigmented network, but a few comedo-like openings within an erythematous-light brown scaly and fissured papule, "moth-eaten" borders, and a central crust due to manipulation, suggesting the diagnosis of seborrheic keratosis...

BACKGROUND: Striae gravidarum (SG) is a common pregnancy-related dermatologic problem, for which finding an effective treatment remains a challenge. AIM: To evaluate the safety and efficacy of 1540 nm non-ablative fractional laser (Star lux 500) in the treatment of SG in Iranian women and peruse the relationship between clinical improvement rate and patient characteristics as well as clinical features of striae. METHOD: A prospective before-after study was conducted on 50 patients with SG who received three monthly sessions of 1540 nm non-ablative fractional laser and were followed for 2 months after the last treatment session...

BACKGROUND: Cellulite of the upper lateral and posterior thighs and lower buttocks represents a common unwanted condition. OBJECTIVES: The author sought to comparea LLLT-LED bed therapy and a novel topical anti-cellulite gel on one thigh/buttock cellulite vs light therapy for cellulite to the opposite side. METHODS: Eight healthy female subjects were randomly treated with a LLLT-LED bed twice weekly for 20 minutes in prone/supine positions with twice daily application of a novel anti-cellulite gel to one randomized thigh/buttock...

Acne scars lead to physical and psychological problems for young adults therefore they should be treated effectively. Fractional carbon dioxide (FCL) and radiofrequency (FRFL) lasers have been both used for acne scars. The aim of this study was to evaluate the effectivity and satisfaction of combined FCL and FRFL treatment for acne scars and evaluate effect of these treatments especially on atrophic scar types retrospectively. A total of 41 patients with acne scars who received FCL + FRFL were included in this study...

Laser-assisted drug delivery (LADD) is a new treatment for delivering drugs within the skin. This meta-analysis investigates the effectiveness and safety of the laser-assisted delivery of tranexamic acid (TXA) to treat melasma. A literature review was conducted by searching publication platforms to search for randomized controlled trials (RCTs) that compared laser-assisted delivery of TXA with laser-alone or topical TXA-alone treatment. The Embase, Web of Science, PubMed, Google Scholar, and Cochrane Library databases were searched, and Melasma Area Severity Index (MASI)/modified MASI (mMASI) scores used as the clinical improvement outcomes...

A chemical peel is chemexfoliation, a process of application of a chemical substance to the skin that causes controlled chemical destruction of the epidermis with or without part of the dermis leading to skin regeneration and remodeling. It can be classified depending upon the depth of penetration into superficial, medium, and deep peels. Among various indications, peels can be used to enhance treatment within a variety of conditions including skin- rejuvenation, inflammatory disorders like acne, rosacea, acne scar, and pigmentary disorders like melasma, freckles, lentigens, dyschromia, and post-inflammatory pigmentation...

Lips undergo several changes with age, decreased volume, elasticity, turgor, and collagen content. Q-switched Nd:YAG laser are known to increase the production of procollagen and elastin and can promote the generation of collagen, which visibly improves facial imperfections. We aimed to determine the efficacy of a 1064 nm Q-switched Nd:YAG fractional laser on improving lip definition, color, and volume. 32 female patients were treated every 2-3 weeks for a total of 3-5 treatments. Improvement was measured in a follow-up visit a month after the final treatment (29...

Non-ablative fractional laser (NAFL) and radiofrequency (RF) are popular for treating periorbital wrinkles owing to short downtime and low risk of side effects. To compare the effectiveness and safety of infrared bipolar radiofrequency (IR-RF) and NAFL, including 1540 nm Er: glass and 1927 nm thulium-doped laser, to determine the better option for clinical treatment of periorbital wrinkles. Twenty-seven patients assigned to 3 groups underwent split-face treatment. Two of the three treatments were randomly selected for patients in each group: IR-RF, 1540 nm Er: glass NAFL, and 1927 nm thulium-doped NAFL...

1,064 nm Q-switched laser has been commonly used to treat pigmentation. However, there is still a lack of research on the treatment of hyperpigmentation caused by topical exposure to metallic salts-related chemical oxidation. We reported an Asian female patient who developed pigmentation 1 year on the face and neck after the recovery from a chemical explosion injury. 1,064 nm Q-switched laser were utilized to treat for 10 years. The facial pigment improved obviously after 10 sessions of treatment of 1,064 nm Q-switched laser...
