Can you use retinol with salicylic acid?
Not together in the same routine. Alternate nights — salicylic acid one night, retinol the next.
Why
Salicylic acid (BHA) is oil-soluble so it's slightly easier on the surface than AHAs, but combined with retinol it still over-stresses the barrier in most users.
How to layer them
Use salicylic acid 2-3 nights a week and retinol on the alternate nights. Always pair with a barrier-supporting moisturiser. SPF every morning, no exceptions.
Pro tip
If you have acne and want both, see a dermatologist about a prescription tretinoin+BPO or adapalene+BPO combination — the formulator does the balancing for you.
