Background: Melasma is a cosmetically disfiguring disorder of facial pigmentation. Objectives: We evaluated the value of platelet-rich plasma (PRP) in the treatment of melasma using two different delivery techniques: microneedling using dermapen versus microinjections using mesoneedles. Patients and methods: Twenty-three adult Egyptian melasma patients were enrolled. ⋯ A statistically significant decrease was noted in the hemi-MASI score on each side of the face following PRP treatment (p < .000), but there was no significant difference in comparing both sides. Conclusions: Our study provides the first indication about the value of PRP as a useful and new therapeutic option in melasma. Moreover, our study was the first to compare PRP delivery through microneedling versus microinjections.

Randomized Controlled Trial
A phase 2, multicenter, double-blind, randomized, vehicle-controlled clinical study to compare the safety and efficacy of a halobetasol propionate 0.01% lotion and halobetasol propionate 0.05% cream in the treatment of plaque psoriasis.
Background: Halobetasol propionate (HP) 0.05% is a highly effective short-term treatment for plaque psoriasis. Objective: Compare efficacy and safety of once-daily HP 0.01% lotion and 0.05% cream (Ultravate®) in moderate-to-severe psoriasis. Methods: Multicenter, randomized, double-blind, vehicle-controlled Phase 2 study (N = 150). ⋯ Conclusions: Halobetasol propionate 0.01% lotion was comparable to the higher concentration halobetasol propionate 0.05% cream; achieving treatment success, reducing psoriasis signs at the target lesion, and improving BSA following two weeks' daily-treatment. Both treatments were well-tolerated. Clinical Trials Registration:clinicaltrials.gov NCT02785185.
