A long-standing player in the world of skin care, peptides are nothing new to experts like Washington D.C. dermatologist Tina Alster, MD. As the ingredient collects its well-deserved time in the limelight, it’s important to know what peptides can offer the skin—and why.
“Peptides are amino acids that are the building blocks of certain proteins of the skin, including collagen and elastin,” explains Dr. Alster. “As such, certain peptides can effectively penetrate the skin to build up collagen to improve skin texture and reduce wrinkles.”
With promising line-ironing results in tow, it’s no wonder why peptides are beloved by experts and all who incorporate them into their routine. Here, impressive formulas boasting the skin-plumping all-star.
