Copper peptides with AHA and BHA exfoliants
Use copper peptides and exfoliating acids such as glycolic, lactic or salicylic acid on separate evenings rather than layered together. Acids are formulated at a low pH and copper peptides close to neutral, and freshly exfoliated skin is also more likely to feel irritated by anything applied straight after.
Why keep them apart?
Two reasons. First, pH: an acid exfoliant needs an acidic formula to work, and a copper peptide serum is formulated close to neutral. Layered wet, neither sits in its ideal conditions.
Second, comfort: skin straight after an acid can feel more reactive, so adding another active on top raises the chance of tingling or redness.
How do you build a week with both?
Two or three evenings a week: cleanse, exfoliant, moisturiser.
The other evenings: cleanse, copper peptide serum, moisturiser.
Mornings: cleanse, moisturiser, SPF. Sunscreen matters more than usual once acids are in your routine.
What about a gentle daily toner?
A very mild acid toner is still an acid. If you use one daily, try it in the morning and keep the copper peptide for the evening.
If your skin feels tight or stings, drop the acid frequency first. It is the more likely cause.
Common questions
Can I use a copper peptide the morning after an acid?
Usually yes. By the next morning skin has settled for most people. If it still feels sensitive, give it a day with just cleanser, moisturiser and SPF.
Should I stop exfoliating if I use copper peptides?
No. Plenty of routines include both. Separating them onto different evenings is simply the gentler way to keep both in your week.
Is salicylic acid different from glycolic acid here?
The advice is the same. Salicylic acid is a BHA and glycolic and lactic acids are AHAs, but all are formulated acidic and are best kept on separate evenings from copper peptides.
