Trends aren't all about hair and makeup. They're about skin care, too. According to Dr. Jeffrey Dover, the dermatologist behind Skin Effects, the antiaging line sold through CVS, it's all about the peptides. Just what are peptides, anyway? Peptides are tiny chains of amino acids that help combat the signs of aging. "Within a few weeks of using products with peptide ingredients, my patients can generally see improvements in the overall appearance of their skin," he said. To learn what's on his "it" list of peptide types — and get a lesson in science — read more below:
- Polypeptides: Commonly known as just peptides. Polypeptides help cells communicate better so that skin looks healthier. They also work to improve the barrier function of the skin, which means less wrinkling.
- Lipopeptides: Because of the fat and water balance, lipopeptides more easily penetrate into the skin, which helps to reduce fine lines and wrinkles, making skin look more firm.
- GABA (Gamma-Aminobutyric Acid): Sourced from tomatoes, GABAs actually help relax the muscles that cause the face to crinkle. They also contain the antioxidant lycopene and promote smooth skin, and are wonderful for those who need instant gratification. I knew I liked those tomatoes.
