Everything You Need To Know About Peptides In Your Skincare

Wouldn't the world be a better place if one product could take care of all your skincare woes? Unfortunately, that magical product is yet to be created. With so many skincare products on the market, it can be overwhelming and confusing to choose the right products for you. While some skincare ingredients actually do what they claim, some ingredients have yet to prove their worth in our vanities. One of the star ingredients that deserves all the recognition is vitamin C, a powerful antioxidant. On this skincare ingredient, Los Angeles-based, board-certified dermatologist Mamina Turegano told Byrdie, "[Vitamin C] also helps build collagen, and can help the superficial skin cells deal with hyperpigmentation." Collagen is responsible for keeping your skin firm and youthful and using vitamin C can increase collagen synthesis in your skin.

Another star ingredient that you have probably heard about is retinol. New York City-based dermatologist Rita Linker told Real Simple, "Also known as vitamin A, this is one of the most effective skin-transforming ingredients." Retinol is a gold standard for anti-aging ingredients because it can help diminish fine lines and wrinkles, fade dark spots and treat acne by speeding up the cell turnover rate on your skin, which slows down with age. You can buy retinol over-the-counter or get a prescription for a stronger retinoid like tretinoin. Now, the spotlight is on peptides, which you must have heard of if you are a skincare enthusiast, though it is lesser known than retinol or vitamin C. Nevertheless, it's worth learning more about.

Peptides give you smoother, firmer, and younger-looking skin

Before dismissing peptides as yet another ingredient, you need to learn what they can do for your skin. "Peptides in skincare products are designed to boost and replenish amino acids, which are the building blocks for collagen production," dermatologist David Kim told Allure, adding that more collagen production means fewer fine lines and less saggy skin. Moreover,, peptides don't have any significant side effects. According to Healthline, "peptides are amino acids that are the building blocks of certain proteins needed by the skin, like collagen and elastin." Using peptides in your skincare is beneficial because the tiny molecules can go deep into your skin and help strengthen your skin barrier and reduce inflammation too.

According to Reserveage's resident dermatologist, Tiffany Libby, various peptides are used in skin care products, and they "act as little messengers and instruct skin cells to perform various functions," per Who What Wear. The four common kinds are signal peptides (promote the synthesis of collagen and elastin), enzyme-inhibiting peptides (prevent the breakdown of elastin), carrier peptides (bring nutrients to the skin for various purposes like wound healing), and neurotransmitter-inhibiting peptides (act like neurotoxins to prevent fine lines). 

Dr. Libby recommends SKINMEDICA TNS Recovery Complex because it has a patented growth factor blend and can "enhance skin texture and tone, and reduce the appearance of fine lines and wrinkles." While peptides need more research, they seem promising and might be a great addition to your vanity.
