Emerging evidenceLactobionic Acid for Rosacea
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.
Why it works for Rosacea
Exfoliates very gently while also holding water in your skin. Many people with rosacea tolerate it when stronger acids like glycolic acid make them sting. It appears in rosacea-friendly exfoliants made for sensitive skin.
How Lactobionic Acid works
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.
