1. Proven Skin-Firming Benefits

Collagen is essential for maintaining the skin’s firmness and elasticity, a fact supported by numerous clinical studies. Research, such as that published in the Journal of Cosmetic Dermatology, demonstrates that ingestible collagen supplements can significantly improve skin hydration and reduce wrinkles.
While topical collagen provides surface-level hydration, dermatologists like Dr. Whitney Bowe note that ingestible forms are better absorbed and utilized by the body for visible anti-aging effects. This dual approach explains why experts recommend incorporating both types into a comprehensive beauty routine.
