Glycolic acid is an AHA that works as a gentle chemical exfoliant, dissolving the bonds that hold dead skin cells on the surface. The result: brighter skin, smoother texture, softened fine lines, minimized pores, help with dark spots and reduced KP bumps. It has the smallest molecule of all AHAs, so it penetrates efficiently while staying gentle.
For the Glycolic Acid Toner: apply to cleansed, dry skin 2–3 evenings a week with a cotton pad, then follow with moisturizer. For the Body Stick: use on areas like arms, legs, back and chest 2–3 times weekly. Always wear SPF the next morning — glycolic acid can increase sun sensitivity.
We recommend alternating them on separate evenings rather than layering — for example, glycolic acid on Monday/Wednesday/Friday and retinol on Tuesday/Thursday/Saturday. This maximizes results while minimizing the risk of irritation. If your skin feels sensitive, reduce frequency.
Yes. Niacinamide pairs well and helps support your skin barrier. For vitamin C, we suggest using them at different times of day (vitamin C in the morning, glycolic acid in the evening) to keep both comfortable and effective.
Glycolic acid can help. By exfoliating and speeding up cell turnover, it helps clear pore-clogging dead skin and fade the look of post-blemish marks and dark spots over time, for a more even-looking complexion.
Absolutely. Glycolic acid is one of the best ingredients for KP — those small, rough bumps on upper arms and thighs. Our Glycolic Acid Body Stick gently dissolves the build-up of dead skin that causes them, with visibly smoother skin in as little as 7 days.*
You may notice brighter, smoother skin within a couple of weeks, while texture and KP typically improve over 4–6 weeks of consistent use. Our Body Stick is clinically proven to visibly smooth KP bumps in as little as 7 days.*
