Bovine collagen is used in some medical and cosmetic applications to support the healing and appearance of scars and scar tissue. Collagen is a major structural protein in the skin, and loss or damage to collagen can impair wound healing and affect scar formation. Bovine-derived collagen has been incorporated into wound dressings, injectable fillers, and other products aimed at supporting tissue regeneration. Scientific evidence suggests that collagen-based dressings can provide a scaffold that supports cellular migration and new tissue formation, which may improve healing and potentially reduce scarring. Some studies have shown that these dressings can enhance wound closure and lead to improved scar quality compared to standard treatments, particularly in chronic wounds or burns.

However, direct evidence specifically linking oral or topical bovine collagen supplements to significant improvements in scar appearance is limited. Most of the scientific support comes from clinical use of bovine collagen in wound care dressings or as an injectable filler for atrophic scars (such as acne scars). While these applications are based on the physiological role of collagen in the skin, the quality and quantity of evidence varies, and most studies are small or not double-blinded. Therefore, while there is some scientific basis for the use of bovine collagen in managing scars—primarily in a clinical setting (e.g., wound dressings, injectable fillers)—the overall strength of evidence is moderate at best.
