Affected women may experience psychological distress and social withdrawal. A variety of laser and light sources have been tried for treatment of hair loss, and some success has been reported. OBJECTIVE: The purpose of this study was to determine the efficacy and safety of a 1550 nm fractional erbium-glass laser in treatment of female pattern hair loss. PAT

The combination treatment with pigmented laser and chemical peeling is effective, safe, and relatively inexpensive treatment modalities in the recalcitrant pigmentary disorders.

BACKGROUND: During the coronavirus disease 2019 (COVID-19) pandemic, various adverse skin reactions to long-term mask wearing have been reported. AIM: To assess the clinical features of mask-induced dermatoses and to recommend prevention and treatment options.

Taken together, these results showed that G-Rg3 induces the activation of ERK, which accounts for its antimelanogenic effects. G-Rg3 may be a promising safe skin-whitening agent, adding to the long list of uses of P. ginseng for the enhancement of skin beauty.

Photoactivation of flavins is coupled productively with the direct transfer of photoinduced electrons to P450s to achieve photobiocatalytic C-hydroxylation reactions in the absence of nicotinamide cofactors.

LED phototherapy on the abdomen produced faster wound healing of the uniform burn wounds than in animals with the same burn wounds that did not receive LED phototherapy, strongly suggesting the systemic effect of phototherapy.

Objectives: The stability of two kinds of solution of penicillin G potassium [PEN-K, 10K U/mL in 5% dextrose water, D5W and 50K U/mL in 0.9% sodium chloride in water, NS) into the intravenous infusion device, Accufuser , storage were evaluated at controlled temperature (CT, 42C and RT, 252C) during 6 weeks.

Background: Acne vulgaris is a prevalent cutaneous disorder that significantly affects patient quality of life. There have been several reports of successful acne treatment using lasers. However, few studies have reported the use of radiofrequency (RF) lasers for acne. Objective: The purpose of this study was to evaluate the efficacy and safety of a noninvasive monopolar RF laser in the treatment of acne vulgaris on the face. Methods: A randomized, prospective, split-face study was performed.

Proliferating trichilemmal cyst(PTC) is a rare benign neoplasm that is thought to be derived from the outer root sheath of anagen hair follicles differentiating toward the infundibular and matrical segments, sebaceous glands, apocrine glands, or acrosyringium. Clinically, it presents as a solitary elevated, lobulated mass on the scalp of elderly women. Histologically, it shows well demarcated multiple lobules of squamous epithelium. The center of the lobule undergoes abrupt keratinization withou
