Glycolic acid is an alpha hydroxy acid - you’ll see this in skincare as AHA - and is derived from sugar cane. It’s just one of a large family of AHAs that also includes lactic acid (from milk) and citric acid (from….yep, citrus fruits).
It’s become a staple in skincare routines thanks to its ability to revitalise and renew the skin. But what sets glycolic acid apart, and how can you harness its benefits? In this guide, we'll explore the science behind glycolic acid, how to get the best from it and which products to start with.
Exfoliation Stations
Glycolic acid is a potent exfoliant with the smallest molecule size of all the AHAs, allowing it to penetrate deeply into the skin. It works by gently dissolving the bonds between dead skin cells, promoting their shedding and revealing fresher, radiant skin underneath.
Collagen Turbocharger
Beyond its exfoliating properties, glycolic acid also stimulates collagen production, leading to improvements in skin texture, firmness, and overall youthfulness over time. Our natural production of collagen falls from our 20s onwards, and glycolic acid can help to slow that process.
Better Skin Tone
The benefits of glycolic acid extend far beyond its exfoliating prowess. By effectively removing dead skin cells, glycolic acid unclogs pores and refines skin texture, resulting in a smoother, more even complexion.
Glycolic acid also helps to improve skin tone, in two different ways. Its brightening properties make it particularly effective in addressing hyperpigmentation, dark spots, and uneven skin tone This property also helps to repair skin that has been harmed by sun exposure, making it the key skincare ingredient in restoring sun damaged skin.
The compound’s ability to stimulate collagen synthesis helps diminish the appearance of fine lines, wrinkles, and other signs of aging, promoting a more youthful, revitalised complexion.
Start Slow and Low
While glycolic acid offers numerous benefits, it's not without some risks to be aware of. Because of it’s exfoliating power it does expose sensitive skin, and too much too soon can result in temporary side effects such as redness, irritation, or peeling. This is especially common when first starting out or when using higher concentrations of glycolic acid.
To minimise the risk of irritation, begin with a lower concentration and apply a few times a week. Over time, and if no irritation is present, gradually increase the frequency as your skin’s tolerance develops.
Sun Sensitivity
Like other exfoliating acids, glycolic acid can increase the skin's sensitivity to the sun, making it essential to use sunscreen daily and limit sun exposure while using glycolic acid-containing products. Consider only using glycolic acid in your evening routine to reduce the risk of a bad reaction with solar radiation.
Combination Stations
Glycolic acid can be safely combined with other skincare ingredients, but it's essential to avoid using it alongside other exfoliants that may increase the risk of irritation, such as retinol or benzoyl peroxide.
Glycolic Acid and Pregnacy
Unlike ingredients like retinol, Glycolic acid is considered safe to use during pregnancy and while breast feeding. For more information see this article from Heathline on use during pregnancy and this story from Drugs.com on using while breastfeeding.
Time is the Master
Visible results may take several weeks to months to manifest, so as with all skincare patience and consistency are key.
