Why copper peptides suit sensitive skin
Unlike retinoids and strong acids, copper peptides don't work by exfoliating or accelerating turnover, so they're far less likely to cause dryness, peeling or stinging. They're also associated with a calmer, more comfortable-looking skin barrier.
How to patch test
- Pick a spotApply a drop to your inner forearm or behind your ear.
- Wait 24 hoursDon't wash the area. Watch for redness, itching or swelling.
- Try your jawlineIf all's well, apply a small amount along your jaw for a couple of days before using it on your whole face.
Introducing it slowly
- Week 1: once a day, at night.
- Week 2 onward: morning and night if your skin is happy.
- Pause other strong actives while you start, so you know how your skin is responding.
If your skin reacts
Mild, short-lived tingling can happen with any new product. If you notice persistent redness, itching or swelling, stop using it and talk to a dermatologist or healthcare provider. If you have a known allergy or skin condition, check the full ingredient list and ask your provider before starting.
