What it actually does: a larger AHA molecule that works more at the surface, so less irritation for slightly slower results. Uniquely, it’s also a humectant - it exfoliates while pulling water in, which no other common acid does.
Who it’s for: first-time acid users, dry or sensitive skin that still wants exfoliation, dullness, mild texture.
How to use it: 5–10%, at night, once or twice a week to start. Same sun rules as every AHA: sunscreen daily or don’t bother.
Honest expectations: softer, brighter skin within two to three weeks. For deeper texture or stubborn pigmentation, you may eventually graduate to glycolic - or find you never need to.
