A beta-hydroxy acid that exfoliates inside pores for a clearer-looking complexion.
More on this ingredient: read the guide.
As with other exfoliating acids, the low pH is commonly cited as a reason to keep BHA and copper peptides in separate routines.
Peptide + BHA caution is largely precautionary for finished products.
Precautionary; the interaction concern is theoretical rather than demonstrated.
As with other peptides, this caution is more lore than established fact.
Two acidic actives in one layer can feel like a lot; many prefer to separate them.
As with AHAs, combining a retinoid and BHA can be a lot for the skin barrier — introduce gradually or alternate.
Combining exfoliating acids increases total exfoliation and the chance of over-doing it — use sparingly and not every day.
Both can be drying; many use them on alternate days rather than the same layer.
A common, comfortable pairing.
No conflict: salicylic acid goes underneath, sunscreen last. An exfoliating acid can leave skin a little more sun-reactive, which is a reason to wear sunscreen rather than to avoid the pairing. Let the salicylic acid absorb first, then apply sunscreen as an even final layer, and reapply through the day as usual.
A sensible counterweight. Salicylic acid clears the follicle and can dry the surface; a ceramide moisturiser afterwards keeps that drying from tipping into a compromised barrier.
