Peptide skincare has some evidence to support its claims, particularly in promoting collagen production and improving skin elasticity, but results vary by individual and product formulation.
What are peptides?
Peptides are short chains of amino acids that act as building blocks for proteins like collagen and elastin in the skin. They are commonly found in skincare products marketed for anti-ageing and hydration.
What does the evidence say?
Research suggests peptides can:
- Stimulate collagen production, which may reduce the appearance of fine lines and wrinkles.
- Improve skin elasticity and firmness.
- Enhance hydration by supporting the skin’s natural barrier.
However, studies are often small or funded by manufacturers, so results should be interpreted with caution.
How to choose a peptide product
When assessing peptide skincare:
- Look for products with a concentration of peptides listed in the ingredients.
- Check for complementary ingredients like hyaluronic acid or antioxidants for added benefits.
- Patch test new products to avoid irritation.
Practical takeaway
Before investing in peptide skincare, start with a single product like a serum or moisturiser to test its effectiveness on your skin. Monitor changes over 4-6 weeks and adjust your routine as needed.
