Clinical Uses of Oral Collagen Peptide Supplementation in Dermatological Consultation

The review explores the clinical uses of oral bioactive collagen peptides (PBCC) in dermatology, emphasizing their role in enhancing collagen synthesis, skin hydration, elasticity, and wound healing. PBCCs show potential benefits for telogen effluvium and hair transplant optimization by activating M2 macrophages and promoting immune tolerance, with no adverse effects reported. While evidence supports their efficacy in skin aging and wound healing, further studies are needed for conditions like xerotic eczema and atopic dermatitis. The review calls for standardized formulations and larger studies to resolve existing controversies.
