How to introduce Ammonium lactate and Betaine Salicylate

  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: Ammonium lactate one evening, Betaine Salicylate the next, so your skin only handles one of them at a time.
  3. Start the exfoliating acid 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: Ammonium lactate and Betaine Salicylate 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.
