Frequently asked questions
What is glycolic acid?
Glycolic acid is the smallest alpha hydroxy acid (76 g/mol), derived from sugar cane. It dissolves the bonds between dead surface skin cells to drive renewal and brightening.
What percentage should I start with?
Beginners should start at 4–7% a few nights per week. Move up to 8–10% only once tolerated. 15%+ formats are weekly peels, not daily use.
Can I use glycolic acid with retinol?
Not on the same night. Alternate — glycolic on one night, retinoid on another — to avoid barrier damage.
Does glycolic acid increase sun sensitivity?
Yes. Daily SPF 30+ is mandatory. Sun exposure on freshly exfoliated skin drives pigmentation, not the acid itself.
Is glycolic acid safe in pregnancy?
Low concentrations (under 10%) are generally considered safe topically, but always confirm with your obstetrician or GP.
Can I use it on my body?
Yes — body lotions with 5–10% glycolic acid help keratosis pilaris, ingrown hairs, and rough texture on arms, legs, and back.
