5 Dermatologist-Approved Serums for a More Youthful-Looking Complexion

This serum is "particularly good for brightening and targeting pigmentation," says Herrmann. "Its highly concentrated vitamin C (L-ascorbic acid) acts as an antioxidant that squelches damaging free radicals and helps stimulate collagen synthesis for tighter skin," she explains. "Although many vitamin C [serums] are on the market, it's an inherently unstable and light-sensitive molecule. Ferulic in this serum helps stabilize the vitamin C, and the product's dark bottle helps keep it active by protecting it from light."

"For a less expensive drugstore option, I like Olay Regenerist," says Herrmann. "Peptides help stimulate collagen synthesis, and the serum's nicotinamide helps reduce redness, which is especially useful in acne- and rosacea-prone skin," she explains. "It's also fragrance-free, which is perfect for sensitive skin types."

"In the winter, dry and irritated skin is common," says Herrmann. "The above is a hydrating and healing serum that doesn't cost a fortune. Its hyaluronic acid acts as a cloud cream binding water molecules, and its oatmeal and aloe help soothe inflamed skin."

"This is a great option for those with acne prone skin," recommends Herrmann. "Retinol helps encourage cell turnover, and AHAs help gently exfoliate, encouraging brighter and blemish-free skin."

"Our number one favorite serum is DNA Regeneration Serum," say Herrmann and Chipps. "It has high concentrations of plant-based growth factor sourced from Iceland," they explain. "It's clinically proven to reduce the appearance of pores, fine lines, wrinkles, irregular pigmentation, and photo damage as well as improve skin texture in as little as eight weeks. You'll see a more even skin tone, a redefined skin texture, and a reduction in skin discoloration and age spots. It's also suited for all skin types."
