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. Significantly more hairs were counted using the dermatoscope than using the digital camera (76.9 ± 41.3 vs. 58.6 ± 31.4, p < .005), independently of hair thickness and hair density. The difference in hair counts between the two instruments was inversely related to hair thickness and directly related to hair density. The handheld dermatoscope may be a more effective tool than the widely used digital camera in evaluating the response to laser hair removal treatment.

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.

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.

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. Inconsistency and small study effects were examined by design-by-treatment interaction model and comparison-adjusted funnel plot.
Results: A total of 13 randomized controlled trials (RCTs) (n = 652) were contributed to network meta-analysis. Pooled results revealed that diode laser showed significantly lower absolute hair count within three-month (SMD = -13.21, 95% confidence interval [CI]: -22.25 to -4.17) and around six months follow-up (SMD = -11.01, 95% CI: -18.24 to -3.77) as compared with those in control group, but no significant difference among laser interventions. All side effects observed were transient without leaving any permanent scars.
Conclusion: Eliminating unwanted hair with lasers or intense pulsed light is safe and effective; however, which type of intervention is more beneficial in the long-term process should be studied with a longer follow-up time.

A 33-year-old female, Fitzpatrick IV phototype, developed varicella zoster eruption over the ophthalmic dermatome of the right trigeminal nerve, confirmed through Polymerase Chain Reaction, 4 weeks after recovering from COVID-19 disease. After the resolution of the acute manifestations, she developed significant atrophic scars on the forehead, about 2 mm deep, with marked post-inflammatory hyperpigmentation. She came to our clinic looking for treatment, as the scars caused significant psychological distress. We decided for a combination treatment with Erbium:glass 1540 nm non-ablative laser and 755 nm Alexandrite picosecond laser. After 16 weeks of starting treatment, significant improvement was observed, with complete resolution of the hyperpigmentation and overall improvement in the atrophic scar. No complications occurred during the treatment period. This strategy may be an effective and safe option to treat these lesions, which may be increasingly found in young individuals after COVID-19 disease or SARS-CoV-2 vaccination, even in darker skin phototypes.

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. No recurrence or adverse events occurred during 10 years of treatment and follow-up, while the progression of lesions on the neck was observed.

Scars may be devastating for patients. Fat grafting and non-ablative lasers are available options for improvement. The former reshapes and improves scar quality by adding volume and regenerative adipose-derived stem cells, whereas the latter facilitates synthesis and deposition of new dermal collagen. The combination may be synergic, leading to better cosmetic outcome.This was a prospective study of 16 consecutive patients treated with autologous fat grafting and non-ablative 1540-nm erbium laser for facial scars between January 2015 and December 2015. Treatment protocol included fat injection followed by five treatments with 1540-nm erbium laser (ICONTM Cynosure; Westford, MA, USA) a month later. We evaluated patients before, after treatments, and 6 months after the final treatment.Sixteen patients participated in our study. Mean patient age was 42 years (range 16-59 years). Scars were either traumatic (73%) or acne induced (27%). Traumatic scars were mainly new scars, with the majority of patients were treated within 30 days of injury. There were no reported complications. Scars improved in both texture and appearance and patient satisfaction was high in all cases.Treatment of scars with autologous fat grafting and fractional non-ablative 1540-nm erbium laser is safe and efficient and results in improved scar appearance and texture.

Photobiomodulation therapy (PBMT) has become an adjuvant therapeutic possibility in body remodeling procedures. Given this scenario, this study was proposed with the aim of evaluating the effects of PBMT to Light Emitting Diode (LED) associating the red (630 nm) and infrared (850 nm) wavelengths in the subcutaneous fatty tissue. This controlled study of comparative intervention that evaluated a sample of subcutaneous fatty tissue from women with grade II obesity. The participants received the LED PBMT treatment with associated red and infrared wavelengths sequentially on the left side of the abdomen and the right side was considered as control, with the collection of biological material performed at the time of bariatric surgery. For histological and immunohistochemical evaluation, Caspase 3, Cleaved Caspase 3, CD68+, HSL and adipophilin markers were used. The participants showed positivity in the expression of Caspase 3 and Cleaved Caspase (p < .0001), CD68+ macrophages (p < .0001), HSL (p < .0001) and adipophilin (p < .0013) in the intervention sample when compared to the control. PBMT and LED associating red and infrared wavelengths were able to promote autophagic lipolysis induced by adipocyte cell apoptosis in the subcutaneous tissue of obese individuals.
