Which one goes first?

Apply Vitamin C (LAA) first

  1. 1Cleanse
  2. 2Vitamin C (LAA)
  3. 3Acetyl Tetrapeptide-5
  4. 4Moisturize

On freshly cleansed skin, Vitamin C (LAA) goes on first, then Acetyl Tetrapeptide-5 over it. The rule of thumb is thinner and lower-pH first, richer last.

Adding Acetyl Tetrapeptide-5 and Vitamin C (LAA) 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.

For your skin type Sensitive skin should ease in gently: Vitamin C (LAA) can be mildly irritating on its own, and more so alongside another active.
