The Best Anti-Aging Ingredients on the Market, According to Science

Aside from sunscreen, retinoids are the rulers of anti-aging skin care, especially where scientific data is concerned. "I love this ingredient for its ability to increase cell turnover, help the skin look younger and protect skin cells from free radicals," says board-certified dermatologist Dr. Marina Peredo. "Applying retinol can slow down the aging process and firm up the thin skin and fix any crepey texture. It can also reduce hyperpigmentation, age spots and acne scars."
