From bakuchiol to hyaluronic acid to niacinamide, there is no shortage of trendy ingredients to choose from in skin care products. Peptides, while not exactly new, are another ingredient you've probably seen listed on countless product packages, but you may have no idea what they actually do. Is this an ingredient you should be looking for? Are they safe to use?
In short, yes. Peptides are a harmless ingredient that generally won’t negatively affect you, explained Dr. Susan Massick, board-certified dermatologist at The Ohio State University. To gain a greater understanding of the commonly-touted skin care ingredient, Shop TODAY asked Massick for her expert insight.

How do peptides work for your skin?
“Peptides are basically a short chain of amino acids,” Massick said. “Amino acids are the building blocks of proteins, so peptides are a generic term for small chains of these amino acids.”
Studies have shown that peptides can help repair your skin barrier or produce collagen when used in certain products or combinations. However, with surrounding science still being so new, there’s no concrete long-term evidence of its anti-aging benefits yet, she explained.
“While they may be nourishing, hydrating [or] moisturizing [for your skin], in terms of [whether] they really reverse aging? It may not necessarily be as effective as they’d hope."
Despite the lack of current data available on the ingredient, she assured us that peptides are very safe to use. “They’re not harmful in any way and I think that’s important in terms of trying to find all these products,” she said.
Unlike other ingredients that can irritate your skin, Massick says that’s typically not the case with peptides. In fact, certain peptides have been shown to have anti-inflammatory properties, according to a 2018 study.
But again, don’t expect to see miracles from solely using products with peptides. “Some of them look really interesting in terms of all the things that they promise on their packaging but in terms of 100 percent age reversal, it's probably not going to happen,” she advised.
Tips for using skin care products with peptides
When looking for a product with peptides, Massick recommends opting for creams and serums. “I don’t think they’re necessarily as effective when they’re in the washes because they don’t really have enough time to penetrate the skin when you just put them on and directly rinse them off,” she elaborated.
When you find a product you want to try, Massick stresses the importance of starting with a test area to assess any irritation that may arise and checking the other ingredients that are in the formula. She says that oftentimes peptides work synergistically with ingredients like vitamin C, hyaluronic acid and niacinamides, so you should keep an eye on the ingredients list to see if any of these or other beneficial skin care ingredients are present.
Like every dermatologist, Massick also stressed the importance of making sure you have proper sun protection in your skin care regimen. “That’s really what’s going to be driving…the changes to the skin that we’re trying to combat and reverse with these products,” she said.
