What Are Peptides in Skincare? Our Guide to Their Benefits, Uses & Best Formulas

Want skin that looks firmer, smoother and more resilient? Peptides are one of skincare's most trusted ingredients for supporting skin’s natural collagen, improving the look of fine lines and helping skin maintain a healthy-looking appearance. Discover exactly what this powerful ingredient is, what it can do for skin and the peptide-powered products that can help elevate your daily regimen.

What are peptides?

Peptides are short chains of amino acids—the building blocks of proteins. In the skin, they can strengthen skin’s support network, which can help contribute to skin's firmness, elasticity and overall healthy appearance.

How do peptides in skincare work?

As collagen naturally declines with age, skin can begin to lose firmness and elasticity. Peptides can help support skin by encouraging the processes that keep it looking smoother and more resilient. Over time, skincare formulas with peptides can help:

• Improve firmness
• Reduce the appearance of fine lines and wrinkles
• Support skin's moisture barrier
• Enhance smoothness and texture
• Promote a more radiant-looking complexion

How often can I use peptides in my skincare routine?

Most formulas are designed for daily use. You can typically apply them once or twice a day in your morning and nighttime skincare routine, depending on the product instructions and your skincare routine. For the best results, consistency matters. Regular use can help support smoother, firmer and healthier-looking skin.

What other skincare ingredients do peptides pair well with?

While it depends on the specific formula, peptides can pair well with hydrating ingredients like Hyaluronic Acid and can also complement other anti-aging ingredients such as Niacinamide and Antioxidants. They can also be used alongside Retinol or Vitamin C in most routines. If you have sensitive skin, introduce new active ingredients gradually to minimize irritation.
