How to introduce Citric Acid and Retinyl 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: Citric Acid one evening, Retinyl Retinoate 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 Sensitive skin should ease in gently: Citric Acid and Retinyl Retinoate can be mildly irritating on their own, and more so alongside another active.
