Niacinamide and isopropyl alcohol: keep them apart

Keep them apart

Apply niacinamide first and wait until dry, then apply the alcohol product if needed, because heavy alcohol stops your skin from absorbing niacinamide. Heavy alcohol dries out and damages your skin barrier, which makes niacinamide much harder to tolerate. You can switch to a lower-alcohol formula or space the products further apart.

Questions and answers

Can you use niacinamide and isopropyl alcohol together?

You should keep niacinamide and isopropyl alcohol apart because alcohol disrupts the skin barrier and reduces niacinamide absorption. If you want to use both, opt for low-alcohol or alcohol-free formulas to protect your skin's tolerability.

Which goes first, niacinamide or isopropyl alcohol?

Keep niacinamide and isopropyl alcohol apart in your routine because high alcohol or solvents may dehydrate your skin and reduce niacinamide absorption. If you use both, choose low-alcohol or alcohol-free formulas to help protect your skin barrier.

Are niacinamide and isopropyl alcohol good for sensitive skin?

Keep niacinamide and isopropyl alcohol apart, especially on sensitive skin, because alcohol disrupts the skin barrier and reduces niacinamide absorption and tolerability. You should avoid combining them in the same routine, opting instead for alcohol-free or low-alcohol formulas.
