Peptides are small proteins made up of amino acids that can have various benefits for the skin depending on the type of peptide used. Signal peptides can enhance collagen and elastin production, carrier peptides can help deliver vital ingredients to target sites, and enzyme-inhibitor peptides can prevent the breakdown of collagen. Neuropeptides, or neurotransmitter inhibitor peptides, can block the release of neurotransmitters that relay muscle signals, reducing expression lines on the face. Peptides can offer anti-aging benefits when included in a skincare routine.
When looking for a peptide serum, it is important to choose a formula that combines peptides with other beneficial ingredients such as hyaluronic acid, ceramides, and glycerin. These additional ingredients can help protect the skin barrier and keep the skin hydrated and smooth. Signal peptides and carrier peptides are among the most studied and effective peptides for anti-aging benefits, with copper peptides being one of the most commonly used. Choosing a peptide serum that addresses specific skin concerns, such as hydration or firmness, can further enhance its effectiveness.
Peptide serums are recommended for those who already use antioxidant serums, retinoids, and sunscreen as part of their skincare routine. Peptides can add to the anti-aging benefits of these products and provide a preventative effect against signs of aging such as fine lines and wrinkles. The longer peptides are used, the more benefits can be seen in terms of firmer, brighter skin and slowed aging. Peptide serums are also a good option for those who cannot tolerate irritating ingredients like retinoids, as they offer similar benefits in stimulating collagen production without the risk of irritation.
Experts such as Dr. Carmen Castilla, Dr. Melanie Palm, and Dr. Jeanette Graf recommend peptide serums as a valuable addition to an anti-aging skincare routine. Peptides can help improve collagen production and overall skin health, leading to plumper, smoother skin and a reduction in fine lines and wrinkles. Peptide serums are suitable for a wide range of skin types and concerns, and can be used as a preventative measure against signs of aging. By choosing a peptide serum with the right combination of ingredients and targeting specific skin concerns, users can maximize the benefits of peptides for their skin.
