Dermatologist: Collagen Creams and Powders Don't Magically Rejuvenate Skin

A dermatologist explains that collagen applied topically in creams and masks cannot penetrate the skin barrier in active form — the molecules are too large. Oral collagen supplements may supply amino acids, but there is no guarantee they will reach the skin specifically. Sun protection, adequate hydration and a healthy lifestyle are the most decisive factors for skin condition.
