Stem cells are a new, innovative treatment in cosmetic dermatology that is being incorporated to treat a wide variety of skin conditions, including acne scars. Stem cells are cells that have not been differentiated or assigned a specific function. In theory, stem cells can differentiate into fibroblasts, the cell type responsible for making collagen, to increase collagen production and accelerate healing. These stem cells can be derived from various types of tissues, including bone marrow, umbilical cord blood, and adipose tissue. While some clinics have incorporated stem cells into laser resurfacing treatments or microneedling with PRP with some success, more research needs to be conducted to determine its safety and efficacy in acne scar treatments.
