Peptides in Skincare: Benefits, Evidence, and Formula Choices

Short Answer

Peptides are short chains of amino acids used in skincare for purposes such as improving the appearance of fine lines. Evidence varies by peptide and formula, so one product’s results do not apply to every peptide serum.

Benefits

• Some tested peptide formulas improve visible fine lines.
• Can be part of a moisturizing routine for aging-looking skin.
• Offer formula options for people who prefer to avoid adding another exfoliant.

How to Use

Apply according to the product directions, usually before or within the moisturizer step. Choose one formula that fits your main concern. Keep track of comfort and visible changes over time instead of adding several peptide products at once.

Is a peptide complex percentage useful?

Only with context. Check what the number describes and whether the finished formula has relevant testing.
