How to introduce Ammonium lactate and Hydroxypinacolone Retinoate
- Patch test each one first: a coin-sized amount on your inner forearm for two or three days, watching for redness or stinging.
- Alternate nights: Ammonium lactate one evening, Hydroxypinacolone Retinoate the next, so your skin only handles one of them at a time.
- Ease the exfoliating acid in slowly: start at two nights a week for the first fortnight, then build up only as your skin stays comfortable.
- 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.
Two strong actives at once is a lot to ask of your skin. Going slow is exactly what keeps this pairing working instead of backfiring.
For your skin type Sensitive skin should ease in gently: Ammonium lactate can be mildly irritating on its own, and more so alongside another active. On the upside, Ammonium lactate leans hydrating or soothing, which helps buffer the rest.
