AHA + niacinamide
What the source says
Skincare.com, a consumer site owned by L'Oreal, quotes two dermatologists who say niacinamide can be used with AHAs. They suggest spacing the products out, either on different days or about half an hour apart in one routine, because layering them may raise the skin's pH and reduce how well they work. Some single products combine niacinamide with an AHA, and the article says to use those as directed without layering other active products on top. We have not tested this pair ourselves.
Where it can still go wrong
AHAs can irritate, especially at higher strengths, and adding more actives makes a routine harder to tolerate. Stop a product that causes ongoing redness, stinging or peeling.
A cautious way to start
Use sunscreen every morning, add one product at a time, and patch-test first. Follow each product's label. Ask a clinician if you use prescription treatments or have a skin condition. Cosmetic guidance, not medical advice.

Skincare.com: can you use niacinamide with AHAs and BHAs?
AAD: testing skincare products
Skincare.com is a brand-owned consumer site quoting two dermatologists, not a trial of this pair. Other consumer pages give stricter "keep them apart" advice, so we describe spacing as a cautious option, not a rule. AAD supports patch-testing.
