Can you use lactic acid with niacinamide?
Yes — lactic acid and niacinamide can be used in the same routine without significant conflict.
Why
Lactic Acid exfoliates while drawing in moisture — gentler than glycolic acid. 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.
Products that contain both lactic acid and niacinamide
These products formulate both ingredients together — the chemistry is balanced for you.
