Collagen Stimulation Essential for Skin Health, Experts Say

Collagen, the most abundant protein in the body, is crucial for skin firmness and elasticity, but production declines with age—about 1% per year starting from the mid-20s, according to board-certified dermatologist Jane Yoo. Stimulating collagen helps prevent sagging, deep wrinkles, and loss of definition. Carrie Gross, co-founder of Dr. Dennis Gross Skincare, emphasizes that consistent use of gentle actives is more effective than occasional strong treatments. Key ingredients include vitamin C, retinoids, peptides, and chemical exfoliants. In-office treatments like fractional laser and microneedling are most effective, while at-home devices such as LED masks offer milder benefits. Genetics influence baseline collagen density, but sun avoidance and consistent skincare can narrow the gap between genetic predispositions. The article advises starting vitamin C from age 20 and using SPF daily.
