Can You Use Niacinamide and Salicylic acid Together?

Yes, they work well together

Yes. Niacinamide doesn’t exfoliate, so it won’t add to the dryness salicylic acid can cause, and both are used for acne-prone skin. Apply salicylic acid first, then niacinamide, then moisturizer.

How to use niacinamide and salicylic acid in one routine

Morning

Salicylic acid cleanser, then niacinamide serum, moisturizer, sunscreen

Night

Same order works at night

If salicylic acid is a leave-on product, give it a minute to absorb before the niacinamide.

Why

Salicylic acid is a beta hydroxy acid that works inside the pore to loosen the plugs behind blackheads and whiteheads. Niacinamide is a form of vitamin B3. In a 1995 trial, a 4% niacinamide gel improved inflammatory acne about as well as a 1% clindamycin gel over eight weeks.

They do different jobs, and only one of them exfoliates. That is why this pairing rarely causes trouble: the irritation that comes from mixing actives usually comes from stacking two exfoliants, not from an exfoliant plus niacinamide.

What to watch for

Salicylic acid alone can still dry or sting, especially in a leave-on form. If your skin gets tight, use it every other day and keep the niacinamide daily.
