Which one goes first?

Either order works

  1. 1Cleanse
  2. 2Benzoyl Peroxide + Vitamin B3
  3. 3Moisturize

Benzoyl Peroxide and Vitamin B3 sit at about the same step, so the order is not critical. As a rule of thumb, apply the thinner, more watery one first, then the richer one over it.

Adding Benzoyl Peroxide and Vitamin B3 to your routine

  1. Good news first: these two get along, so there is no special order or waiting period to manage.
  2. Still add them one at a time, a week or two apart, so if your skin does react you know which one to look at.
