Why you need to start putting glycolic acid on your face. And exactly how.


Look to your left. See your co-worker over there with the annoyingly good skin?

And the women who always look like the picture of health and wellness you know for a fact eat Maccas and might smoke a cigarette on the weekends?

They’re probably putting acid on their faces. Glycolic acid, that is.

If you’re still using an exfoliating scrub with little bits in it, it’s time to catch up and get on the chemical exfoliation train to glowy, radiant skin.

But… why am I putting actual acid on my face again, you ask? Don’t worry, it’s not a dumb question at all.

That’s why we asked a dermatologist to unpack exactly why you need to start putting glycolic acid on your face. And exactly how.

What is glycolic acid?

Think of glycolic acid as the chief of Alpha Hydroxy Acids. They’re commonly labelled on lotions and potions as AHAs.

“Specifically, glycolic acid is an AHA primarily found in sugar cane. It’s a small crystal that is dissolved into a gel or liquid to be applied to the skin and is favoured for it’s water-binding properties and small molecular structure, which can easily penetrate into the skin’s surface and do all the things,” dermatologist Dr Liz Dawes-Higgs told Mamamia.

What does glycolic acid do for your skin?

Put simply, it makes your skin glow.

As for how, Dr Dawes-Higgs likens glycolic acid exfoliation to “removing the ‘glue’ that holds dead skin together.”

It’s not nearly as gross as that sounds though.


Specifically, she explained exactly how the acid works to give you that coveted ‘I drink eight glasses of water a day’ glow.

“Glycolic acid is a peeling agent, a superficial chemical peel, that works on the top layer of the skin to remove the dead cells. This helps to freshen the appearance of skin by evening out skin texture and colour making the skin look brighter or healthier in appearance,” she said.

“When applied to the skin, AHAs work by removing the top layers of dead skin cells. They can also increase the thickness of deeper layers of skin, promoting firmness.”

Aside from it’s knack for cleaning out the gunk in your skin cells that can cause blackheads and whiteheads (shudder), glycolic acid also dabbles in anti-ageing by treating fine lines and overall skin texture.

How is chemical exfoliation different from physical exfoliation?

Exfoliation is exfoliation. Both chemical and physical exfoliation will clear away dead skin and debris living on your lovely face.

It's the how that separates the two.

"Physical exfoliation uses a physical brush or a scrub product to mechanically peel away the dead skin cells," Dr Dawes-Higgs said.

These scrub products can include fruit exfoliants and nut pips such as apricot kernels or walnut shells. Yes, they're Jesus compared to micro beads (the little plastic balls you used to find in some supermarket exfoliant brands).

Proceed with caution though - these physical exfoliants can cause micro tears that leave your skin susceptible to environmental damage, pollution, and sun damage, as skincare expert Paula Begoun told The Cut.

Just to push the knife in a little further, dermatologist and chemical exfoliation expert Dr Dennis Gross told Byrdie physical exfoliation is "primitive" and "like using sandpaper on your face". Yeah.

Chemical exfoliation, on the other hand, is like dusting your face with a feather. Dipped in acid.

"Chemical exfoliation uses an acid, like glycolic acid, to dissolve the dead cells from the top layer of the skin," Dr Dawes-Higgs explained.


Although you wouldn't normally use the word 'gentle' to describe acid, regular use of products with small amounts of AHAs is the gentlest form of exfoliation. There's also zero risk of micro tears.

Is chemical exfoliation suitable for all skin types?

Short answer, yes. But on a couple conditions.

  1. If you have sensitive skin, Dr Dawes-Higgs advised using a product with a lower acid concentration.
  2. Skincare junkies, avoid doubling up on extra strength skincare ingredients - alternate your glycolic acid exfoliant with retinol serums or other AHA products.

If in doubt, start off slow. Yes, doing a patch test is boring and you just want to get the stuff on your face ASAP, but it's worth it if you know your skin tends to freak out about new products.

How to use glycolic acid skincare

The best thing about glycolic acid is it's in so many things. You can get it in cleansers, exfoliating pads, moisturisers, serums and toners - you have options to suit both your needs (i.e. the strength you want) and your budget.

Mamamia's Executive Editor Leigh Campbell - who moonlights as a beauty guru thanks to 15 years' experience as a beauty editor - recommended doing most of your acid exfoliation at night as you won't need to worry about being diligent with sun protection.

If you are applying in the morning, make sure you don't skip your facial sunscreen.

Here are some non-threatening options ranked from affordable to you're not buying brunch this month.
