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: fresher, brighter skin, smoother texture, softened fine lines, less visible pores and reduced KP bumps. Because it has the smallest molecule of all AHAs, 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 moisturiser. For the Body Stick or Body Wash: use on target areas like arms, legs, back and chest 2–3 times weekly. Always wear SPF the next day — glycolic acid can increase sun sensitivity, even on cloudy British days.
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 maximises results while minimising the risk of irritation. If your skin feels sensitive, simply reduce frequency.
Yes. Niacinamide pairs well and can help support your skin barrier alongside exfoliation. With 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.
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 and Body Wash gently dissolve the build-up of dead skin that causes them, with most people seeing smoother skin within a few weeks.
You may notice brighter, smoother skin within a couple of weeks, while texture concerns and KP typically improve over 4–6 weeks of consistent use. Our body range is clinically proven to visibly smooth KP bumps in as little as 7 days.*
Low-concentration glycolic acid like ours is generally considered safe during pregnancy and breastfeeding, but we always recommend checking with your GP or midwife before introducing new actives.
The Toner is a liquid format for facial exfoliation and pore clarity, applied with a cotton pad. The Body Stick is a mess-free solid format designed for precise, targeted use on body concerns like KP and rough patches. Many people use both.
