Which one goes first?

Apply Vitamin C (LAA) first

  1. 1Cleanse
  2. 2Vitamin C (LAA)
  3. 3Coenzyme Q10
  4. 4Moisturize

On freshly cleansed skin, Vitamin C (LAA) goes on first, then Coenzyme Q10 over it. The rule of thumb is thinner and lower-pH first, richer last.

Vitamin C (LAA): Give it eight to twelve weeks, and possibly less: that is simply when it was measured.

Measured on investigator-graded photodamage on the treated half-face (fine wrinkling, roughness, tone); measured at the trial's end, so possibly sooner.PMID 10522500PMID 11896774

Coenzyme Q10 and Vitamin C (LAA): Fine together. They're fine together. These two actually work well together, and are often formulated side by side. Which goes first: Apply Vitamin C (LAA) first.
The short version, if you want to keep it.

Adding Coenzyme Q10 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.
