Ingredient layering
Can you use AHA and BHA together?
Yes — with a little care
Two exfoliating acids at once is a lot for most skin.
How to use them
Use one, or alternate days — and always follow with moisturiser and SPF.
Why
Over-exfoliating shows up as tightness, redness, and a stressed barrier.
The ingredients, in plain terms
Ingredient
AHA
Surface exfoliants that smooth texture and brighten — the water-loving counterpart to BHA.
Ingredient
BHA
An oil-soluble exfoliant that gets inside pores — for blackheads, congestion, and texture that won't smooth out.
