Glycolic Acid 101: Meet the New Star of Your Skincare Routine

What is glycolic acid?

The short cut to clearer, brighter, smoother and firmer skin can be summed up in two words: glycolic acid. Typically derived from sugar cane, it’s an exfoliator that belongs to the alpha-hydroxy acid (or AHA) family, along with lactic, citric and malic acids. Glycolic acid is an incredibly popular skincare ingredient that can be found in everything from cleansers to toners to masks to serums like L’Oréal Paris Revitalift Triple Power LZR Glycolic Acid Serum. In contrast to alternative types of AHA, glycolic acid is a small but mighty molecule with the ability to work on the surface layer of your complexion while also penetrating deeply into the epidermis. An ideal aid for signs of stressed skin, glycolic-acid benefits can deliver a rejuvenating boost to your current at-home skincare routine and transform your bathroom into a DIY treatment room.

Why glycolic acid is amazing

Glycolic acid has earned a solid track record, and it has been well documented by dermatologists as a powerful exfoliator that is an excellent multi-tasker. Troublesome acne? It can help with that. Dullness and dark spots? Consider them gone. As we age, cell turnover naturally slows down and allows dead cells to linger on the surface of skin. Glycolic acid can sweep in and loosen the substance that holds dead cells together, freeing them up to be sloughed off with ease and allowing a fresh, rejuvenated layer to step into the spotlight. By sending dead cells packing, glycolic acid and its benefits can assist a range of skin concerns. The superstar ingredient can also work beyond the upper layer of the epidermis. Its small chemical construction allows it to travel deeper. This helps in the case of blemishes, which are the result of pores and hair follicles clogged by dead skin cells, as well as where hyperpigmentation is a concern. It can also have a positive effect on collagen production, resulting in a firming effect. If you’re experiencing an influx of fine lines, glycolic acid can help with that, too!

A “last but not least” reason to get on the glycolic acid train: It makes everything else you’re already using perform better. Remember all those dead cells? If they’re left to sit on skin, they can hinder the deeper absorption of whatever you’re putting on top, creating an obstacle to efficacy and results. By providing an unobstructed slate, glycolic acid helps to amplify the good stuff. In whisking away excess cellular debris, it can maximize a potent hydrator, like hyaluronic acid, or a protective antioxidant, like vitamin C.

How to use glycolic acid

Now that you know about all the wonderful things glycolic acid can deliver, you’re likely pumped to get in on the action. Before you leap, a little skincare due diligence will set you up for success. Your skin type is a good place to start. The VIP ingredient treats most well and is an ideal match for anyone with a normal, oily or combination complexion. If you have rosacea or extremely dry, reactive or sensitive skin, you should take a pass because you may find this exfoliator too irritating. It’s also important to review what else you’re already using regularly. Adding glycolic acid to the mix isn’t necessary if you’re hopelessly devoted to retinol, which also has a strong exfoliating effect.

Because an exfoliator can make skin more sensitive to the sun, a glycolic-acid-based product can be used at nighttime or in the morning, but using an SPF during the day time like L’Oréal Paris Revitalift Triple Power LZR SPF 30 Day Lotion to protect the skin from UV rays is essential. A serum, like L’Oréal Paris Revitalift Triple Power LZR Glycolic Acid Serum, is an easy upgrade to your at-home skincare ritual. The paraben-, mineral oil- and colourant-free formula balances 10% glycolic acid with soothing aloe vera leaf juice to nourish skin as it exfoliates. Apply it to freshly cleansed skin and you’ll begin to notice a smoother, less congested visage with an elevated glow.
