Which one goes first?

Apply Vitamin C (LAA) first

  1. 1Cleanse
  2. 2Vitamin C (LAA)
  3. 3Thiamidol
  4. 4Moisturize

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

Adding Thiamidol 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: Thiamidol and Vitamin C (LAA) can be mildly irritating on their own, and more so alongside another active.
