A "next-gen AHA" that exfoliates and hydrates at the same time, with much less stinging than glycolic. Sensitive-skin or rosacea-prone users tolerate it where stronger acids fail.

Polyhydroxy bionic acid (galactose + gluconic acid) that gently exfoliates corneocytes while its large polar structure binds water and chelates metal ions, sparing skin from radical-driven irritation.
Why we tier this moderate
4 cited papers across 2 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
