The serum is also super hydrating thanks to hyaluronic acid, so your skin is smooth and taut. As far as where this serum fits into your skin-care routine, you can use it day and\/or night before your oil-based serums (like the brand’s vitamin C or retinal serums) and moisturizers.<\/p>\n
Peptides are short chains of amino acids, “like glycine, arginine, histidine, et cetera,” says Dr. Kim. \u201cThey’re designed to boost and replenish amino acids, which are the building blocks for collagen production.\u201d You might recognize amino acids as the building blocks of protein, but peptides tend to be shorter chains than proteins. And compared to topical collagen, peptides have a small particle size that allows them to penetrate the surface level of your skin at a deeper level. They\u2019re great at reducing the appearance of fine lines and leaving skin firmer, Dr. Kim says.<\/p>\n
The abundance and quality of our body’s natural collagen production decrease over time, as Dr. Hartman previously explained. As a result, wrinkles start to form and skin begins to sag, but peptide chains mimic the structure of amino acids to diminish the look of these concerns. Mature skin, in particular, can benefit from peptides for their ability to improve skin firmness.<\/p>\n
That said, not all peptides are created equal. The most common types of peptides consist of signal peptides, carrier peptides, enzyme-inhibitor peptides, and neurotransmitter-inhibitor peptides, which all have specific functions. (Also, keep in mind that labs and brands can and often do trademark their own peptide complexes.) For example, copper peptides are carrier peptides<\/em>\u2014they activate wound healing and deliver copper to the skin, which, in turn, stimulates collagen production. While you\u2019ll often find “peptides” placed front and center on the actual product packaging, ingredient lists often categorize peptides by how many amino acids a peptide contains, such as dipeptide (two), tripeptide (three), and hexapeptide (six). It’s also not uncommon to see multiple peptides strung together to maximize their collagen-boosting benefits.<\/p>\n Peptides seldom cause skin sensitivity or irritation, but you should still be discerning of your serum\u2019s formulation. “If someone has a [negative] reaction, it’s most likely from the preservatives, other chemicals, or essential oils in the formula, not the peptides,” Dr. Kim says.<\/p>\n When Allure<\/em> tests a product, our editors look at it from every angle to best serve you. We review ingredients, scrutinize brand claims, and, when necessary, examine peer-reviewed scientific and medical studies. In addition to testing every product included in each review, we rely on experts who shape their fields, including dermatology, cosmetic chemistry, and medicine, to help us vet the ingredients and formulas.<\/p>\n For our list of the best peptide serums, we considered each product\u2019s performance across five primary categories: product ingredients and efficacy, packaging, fragrance, texture, and product wear. Our editorial team, which is composed of in-house writers, editors, and contributors, determined that every product excelled in each category\u2014along with special consideration from board-certified dermatologists.

You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure<\/em> wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors\u2014in addition to the wide range of outside testers and industry experts we regularly call upon\u2014is essential to reaching that goal.<\/p>\n After all, can we really<\/em> say a skin-care product is the “best” for people over 50 if the only testers we\u2019ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it\u2019s never been tested on curls? We\u2019re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.<\/p>\n<\/div>\n Elevate your complexion with these Allure<\/em> editor-approved additions to your routine:<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" The serum is also super hydrating thanks to hyaluronic acid, so your skin is smooth and taut.
