Lee YI, Kim S, Kim J, et al. - Researchers assessed the impact of topical post‐laser treatment with adipocyte‐derived stem cell‐containing medium (ADSC‐CM) in combination with niacinamide through a double‐blind, randomized, vehicle‐controlled study. On both sides of the face for skin rejuvenation, 25 patients with aging skin underwent ablative fractional laser (AFL) therapy. For 3 weeks, moisturizers with or without ADSC‐CM plus 2% niacinamide was applied to the specified sides of faces. The post-laser topical application of ADSC-CM in conjunction with niacinamide has been shown to have an anti-aging effect on the skin.
