Can you mix Adapalene and Ammonium lactate?

Same answer whichever way you searched it: Ammonium lactate and Adapalene.

AdapaleneAmmonium lactate

Retinoids and exfoliants both speed up cell turnover, so on the same night their irritation adds up, most of all while your skin is new to either. An AHA also makes skin more sensitive to the sun (measured for glycolic acid, lactic by its class), so the morning sunscreen matters.

Do this: Use them on alternate nights rather than the same evening; once both are old friends, your skin decides.

Which one goes first?

Not on the same night

Use Adapalene and Ammonium lactate on alternate evenings rather than layering them together.

Adapalene: Give it eight to twelve weeks, and possibly less: that is simply when it was measured.

how it was measured

Measured on inflammatory lesion count, investigator-counted; measured at the trial's end, so possibly sooner.PMID 9990421PMID 23725303

Ammonium lactate: Reckon on two to four weeks. No trial pins the exact point down; that is the standard clinical expectation.

how it was measured

Measured on xerosis severity - scaling and roughness, investigator-graded, with corneometer hydration alongside; the clinical consensus; no trial pins the point.PMID 2808786PMID 8125701PMID 11978141PMID 9680769

The short version, if you want to keep it.

How to introduce Adapalene and Ammonium lactate

  1. Patch test each one first: a coin-sized amount on your inner forearm for two or three days, watching for redness or stinging.
  2. Alternate nights: Adapalene one evening, Ammonium lactate the next, so your skin only handles one of them at a time.
  3. Start the retinoid at once or twice a week and increase gradually, giving your skin time to settle between steps.
  4. If skin turns tight, flaky, red or starts to sting, drop back a step and let your barrier recover for a few days before pushing on again.

There is room for both here, as long as you build up gently and let your skin set the pace.

For your skin type Sensitive skin should ease in gently: Adapalene and Ammonium lactate can be mildly irritating on their own, and more so alongside another active. On the upside, Ammonium lactate leans hydrating or soothing, which helps buffer the rest.
