If you’re chasing that smooth, luminous, “just-had-a-facial” glow, glycolic acid might be your new skincare hero. This powerhouse ingredient — a type of alpha hydroxy acid (AHA) derived from sugar cane — works by gently dissolving the bonds that hold dull, dead skin cells on the surface. The result? Fresher, brighter, and more even-looking skin that feels silky to the touch. But with great exfoliating power comes great responsibility: use it the wrong way, and you could end up with irritation or sensitivity instead of radiance. In this guide, we’ll take you through exactly how to use glycolic acid safely and effectively — from choosing the right product and frequency to layering it correctly with your other skincare essentials. Get ready to reveal your most radiant complexion, one step at a time.
Step 1: Start with a Clean Canvas
Before applying glycolic acid, make sure your skin is thoroughly cleansed. Use a gentle, non-exfoliating cleanser to remove dirt, oil, and makeup without stripping your skin’s natural moisture. Avoid using scrubs or other exfoliating ingredients at this stage, as overdoing it can lead to irritation once glycolic acid is applied. Pat your skin dry with a soft towel, leaving it completely clean and free from residue. Starting with a fresh, balanced surface allows glycolic acid to penetrate more effectively, helping it remove dead skin cells and reveal the brighter, smoother layer underneath.
Step 2: Apply Glycolic Acid Carefully
When using glycolic acid, less is definitely more. Apply a thin, even layer using a cotton pad or your fingertips, depending on your product’s format, whether it is a toner, serum, or treatment. Focus on areas that tend to be dull or congested, avoiding the eye and lip areas. If you are new to glycolic acid, start slowly with once or twice a week to allow your skin to adjust. Over time, you can gradually increase frequency. A light tingling sensation is normal, but burning or redness means it is time to rinse and reduce usage.
Step 3: Let It Work — Then Neutralise if Needed
Allow glycolic acid to work for the time recommended on your product, usually a few minutes for at-home treatments. If you are using a rinse-off mask or peel, follow the instructions precisely, as leaving it on too long can cause irritation. For leave-on formulas like toners or serums, let the product absorb fully before moving on to the next step. If your product requires neutralisation, use cool water or the accompanying neutraliser to stop the exfoliation process. Always listen to your skin. If it feels tight or sensitive, shorten your treatment time.
Step 4: Hydrate and Soothe
After exfoliating, your skin needs replenishment. Follow up with a hydrating serum or nourishing moisturiser to lock in moisture and calm any potential sensitivity. Look for ingredients such as hyaluronic acid, ceramides, or aloe vera, as these help restore the skin’s barrier and maintain balance. Avoid using other strong actives like retinol or vitamin C immediately afterward, since your skin will be more vulnerable. This step ensures your complexion stays plump, smooth, and radiant rather than tight or flaky. Glycolic acid resets your skin, and hydration is what seals in the glow and keeps it healthy.
Step 5: Don’t Skip SPF
This is the most crucial step. Glycolic acid increases your skin’s sensitivity to the sun, which makes SPF non-negotiable. Apply a broad-spectrum sunscreen with at least SPF 30 every morning, even on cloudy days. This protects your newly revealed skin from UV damage, pigmentation, and premature ageing. If you use glycolic acid at night, make sunscreen part of your next-day routine without fail. Consistent sun protection not only preserves your glow but also ensures that all your hard work with exfoliation does not go to waste. Radiant skin starts with smart care, and sunscreen is your ultimate safeguard.
