Can you use salicylic acid and glycolic acid together?
Use with caution
Yes, but carefully. Salicylic Acid and glycolic acid can be combined, but the pairing raises the chance of irritation.
Why
Some products combine AHAs and BHAs at low strengths, but layering two separate exfoliants often leads to over-exfoliation.
How to use them
Pick one exfoliant per routine. If you use both, alternate nights and keep strengths low.

- Stinging and redness, especially at higher strengths
General layering tips
- Introduce one new active at a time and give it 2–4 weeks.
