Could AHAs (glycolic / lactic acid) be why your skin keeps reacting?
If a product "breaks you out" for no obvious reason, a hidden ingredient is a common culprit — and because ahas (glycolic / lactic acid) rarely appears under its plain name, it's easy to keep buying it by accident across totally different products. Reactions can look like redness, stinging, small bumps, itchiness, or a rash where you applied it. The pattern to watch for: it happens with several products that seem unrelated, but share one of the names above.
What to do if you think you're reacting to AHAs (glycolic / lactic acid)
- Stop and simplify. Pause new products and go back to a bare-minimum routine (gentle cleanser + moisturizer + SPF) until your skin calms.
- Read the labels you already own. Check every product's full ingredient list for the hidden names above — you may find the same one hiding in several.
- Patch test before reintroducing. Dab a new product on your inner forearm for a few days before putting it on your face.
- See a professional for anything severe or spreading. A dermatologist can patch-test you properly. This page is education, not medical advice.
