Can you use mandelic acid with niacinamide?
Yes — mandelic acid and niacinamide can be used in the same routine without significant conflict.
Why
Mandelic Acid exfoliates the most slowly and gently of all the AHAs — well suited to sensitive skin. Niacinamide regulates sebum, reduces redness, supports the barrier and brightens uneven tone. The two work through different mechanisms with no documented chemistry or irritation conflicts at typical cosmetic concentrations.
How to layer them
Apply the lighter, water-based product first, wait 30-60 seconds for absorption, then the heavier or oil-based product. Standard time-of-day rules apply.
