Quick answer
Peptides are the gentle end of anti-ageing — slower than retinol, but usable by skin that retinol defeats.

1. A short chain of amino acids
A short chain of amino acids — the building blocks of proteins like collagen. Applied topically, certain peptides signal skin to behave as though it needs to repair, which supports firmness and barrier function.
Honest expectations
2. Supportive, not transformative
Peptides are supportive, not transformative. The evidence is real but modest compared with retinoids. Results take months, and they are subtle.
Who they suit
3. Skin that cannot tolerate retinol
- Skin that cannot tolerate retinol
- Anyone pregnant or breastfeeding (generally considered safe — confirm with your doctor)
- Barrier repair alongside ceramides
- People who want an easy addition with almost no irritation risk
How to use
4. Any time of day, under moisturizer
Any time of day, layered under moisturizer. They combine comfortably with niacinamide, hyaluronic acid and ceramides. Avoid using in the same routine step as strong acids, which can break them down.
What they will not do
5. They do not replace sunscreen or retinol
Replace sunscreen, fade dark spots meaningfully, or match retinol for fine lines.
