How to introduce Glycolic acid and Lactobionic 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: Glycolic acid one evening, Lactobionic Acid the next, so your skin only handles one of them at a time.
- Start the exfoliating acid at once or twice a week and increase gradually, giving your skin time to settle between steps.
- 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 If your skin is sensitive or reactive, take this pair slowly: Glycolic acid is the higher-irritation ingredient here, and using actives close together magnifies that. On the upside, Lactobionic Acid leans hydrating or soothing, which helps buffer the rest.
