How to introduce Hydroxypinacolone Retinoate and Mandelic Acid
- 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: Hydroxypinacolone Retinoate one evening, Mandelic Acid the next, so your skin only handles one of them at a time.
- Ease the retinoid 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 Both sit low on the irritation scale, so most skin types get on with them, though sensitive skin should still add one at a time.
