Glycolic Acid is one of skincare’s hardest-working ingredients, loved by experts for its ability to transform dull, uneven skin into a smooth, radiant glow. But how does it work, what skin concerns does it help with, and how do you use it safely? In this guide, we’ll break it all down in simple, no-nonsense terms—plus answer your most Googled questions about glycolic acid and other skin ingredients you can use it alongside.
What Is Glycolic Acid?
Glycolic acid is part of the alpha hydroxy acid (AHA) family, a group of naturally derived exfoliants. It comes from sugarcane and has the smallest molecule size of any AHA, meaning it penetrates your skin deeply for maximum effectiveness. Think of it as a chemical exfoliant that dissolves dead skin cells on the surface, helping to reveal fresh, healthy skin underneath. It’s your glow-up in a bottle!
What Does Glycolic Acid Do for Your Skin?
Here’s why glycolic acid is a game-changer:
- Exfoliates Gently: Breaks down the bonds between dead skin cells for a smoother, brighter complexion.
- Boosts Radiance: Clears away dull skin to reveal your natural glow.
- Fades Dark Spots: Targets hyperpigmentation and evens out skin tone.
- Helps with Acne: Unclogs pores and reduces breakouts caused by a build-up of dead skin cells.
- Minimises Fine Lines and helps with anti-ageing: Encourages collagen production, improving the look of fine lines over time.
It’s perfect for tackling common concerns like dullness, uneven skin texture, acne scars, and early signs of ageing.
Does Glycolic Acid Work for All Skin Types?
Glycolic acid can benefit most skin types, but how you use it depends on your individual needs:
- Oily/Acne-Prone Skin: Reduces clogged pores, prevents breakouts, and improves texture.
- Dry Skin: Gently removes flaky patches and preps skin for better hydration.
- Normal Skin: Maintains radiance and keeps texture smooth.
- Mature Skin: Boosts collagen production for firmer, younger-looking skin.
Note for Sensitive Skin: Glycolic acid can be too strong if your skin is reactive. Start with a low concentration (5-7%) and patch test first.
Does Glycolic Acid Lighten Skin?
Yes—but not in the way you might think. Glycolic acid doesn’t bleach your skin; instead, it helps by exfoliating away dead cells and reducing the appearance of dark spots or uneven pigmentation. Over time, this reveals a brighter, more even-toned complexion.

Does Glycolic Acid Help with Acne?
Absolutely. Glycolic acid works by unclogging pores, removing the dead skin cells that trap oil and bacteria (the main culprits behind breakouts). It also helps to fade post-acne marks, making it a must-have for clearer, smoother skin.
How Long Does Glycolic Acid Take to Work?
You’ll notice smoother, more radiant skin after a few uses—sometimes within a week. However, for bigger concerns like acne scars or dark spots, consistent use over 4-6 weeks will yield the best results. Patience is key! Why not try our brightening skincare routine and test the results in 4 weeks?
What Can and Can’t You Mix with Glycolic Acid?
One of the most common skincare questions is about pairing glycolic acid with other active ingredients. Here’s a breakdown:
Ingredients That Work Well with Glyclic Acid
Niacinamide These two are a dream team. Niacinamide calms the skin and strengthens its barrier, balancing glycolic acid’s exfoliating power.
Hyaluronic Acid Use after glycolic acid to lock in hydration and keep your skin plump.
Vitamin C While both are powerful, they work best at different times of day—use glycolic acid at night and vitamin C in the morning.
What to Avoid with Glycolic Acid:
Retinol Both are potent ingredients, and using them together can irritate the skin. Alternate between glycolic acid and retinol on different nights.
Other AHAs/BHAs: Combining multiple acids (like salicyclic or lactic acid) can lead to over-exfoliation. Stick to one at a time.
Benzoyl Peroxide:Can be too harsh when layered with glycolic acid, leading to redness or dryness.
Expert Tip:When introducing new combinations, start slow with lower concentrations of skincare ingredients and patch test to avoid irritation.
