Combined subcision, autologous platelet-rich plasma, and CROSS technique in the treatment of atrophic acne scars: Prospective split face study.

Acne scars represent a therapeutic dilemma. This study aimed to evaluate the efficacy of combined subcision, autologous platelet-rich plasma (PRP), and chemical reconstruction of skin scars (CROSS) technique in the treatment of acne scars. In 20 patients with atrophic acne scars, one facial side was treated with subcision plus PRP, and the other was treated with the same combination plus CROSS technique (trichloroacetic acid 50%) for 3 sessions at 3-week intervals.

Comparative study of fractional CO laser and fractional CO laser-assisted drug delivery of topical steroid and topical vitamin C in macular amyloidosis.

Macular amyloidosis (MA) represents a common variant of primary localized cutaneous amyloidosis. It has a characteristic female predominance; none of the treatment modalities described is either curative or uniformly effective in patients with macular amyloidosis. To determine the effect of fractional CO laser in macular amyloidosis in comparison to fractional CO laser-assisted drug delivery of topical steroids and topical vitamin C, the study includes 10 female patients with cutaneous macular amyloidosis aged between 20 and 62 years.
