5 Glycolic Acid Benefits for Your Skin That Might Surprise You

Finding the right ingredient to elevate your skincare routine can make all the difference, and glycolic acid is one of our favorites. As you may know, there’s a lot of hype around glycolic acid benefits for skin, and we’d say that’s warranted. Glycolic acid products can brighten dull skin, minimize the look of fine lines, and diminish the appearance of dark spots—and that’s just to start. Ahead, we’re sharing everything you need to know about glycolic acid for skin, spilling on the ingredient’s many benefits, and sharing tips on how to incorporate the powerhouse acid into your regular skincare routine.

What is Glycolic Acid?

Glycolic acid is an alpha-hydroxy acid (AHA) derived from sugarcane. According to the Cleveland Clinic, AHAs like glycolic acid help exfoliate, turning over layers of dead skin cells on the surface of your skin. With consistent use, products with glycolic acid can help improve skin texture and tone. While primarily used in skincare, glycolic acid also has applications in other industries—it’s even gaining traction as a worthwhile haircare ingredient.

What does glycolic acid do?

Glycolic acid works as a chemical exfoliant, gently breaking down the bonds between dead skin cells on the skin's surface, allowing them to be easily sloughed away. This process helps reveal fresher, more radiant-looking skin underneath and improves the appearance of skin texture and tone. However, according to the Cleveland Clinic, glycolic acid uses extend beyond simple exfoliation. With consistent use, it can also help encourage collagen production to support a firm, supple complexion.

Who should use glycolic acid?

Anyone looking to improve their skin’s texture and tone may want to try glycolic acid. This ingredient can be especially useful for individuals with dull, uneven, or sun-damaged skin, as it promotes a more radiant and even-looking complexion. Those struggling with fine lines, wrinkles, or dark spots may also find glycolic acid effective in addressing their skin concerns.

It's important to note that glycolic acid products aren’t one-size-fits-all—there are different concentrations available, from ultra-mild to relatively potent. If you’re new to chemical exfoliants, we generally recommend starting with a lower concentration until your skin acclimates. You can also consult your dermatologist for help pinpointing a formula that suits your skin’s unique needs.

What Are the Benefits of Glycolic Acid?

Glycolic acid benefits go beyond surface-level improvements, addressing everything from tone and texture to how well your other products perform. Here’s a closer look at the transformations you can expect when incorporating this ingredient into your routine.

1. Brighter-looking skin

As mentioned earlier, glycolic acid is a chemical exfoliant, meaning it encourages skin cell turnover. By helping to clear away dull, dead surface cells, glycolic acid products—such as glycolic acid serums or toners—can help brighten the skin, revealing a more radiant, luminous complexion over time.

2. Faster product absorption

By helping to remove dead skin cells, alpha-hydroxy acids like glycolic acid can help your skin better absorb other skincare products, such as essences, serums, and moisturizers.

3. Fewer wrinkles

One of the best-known glycolic acid serum uses is for anti-aging. When used consistently, products with glycolic acid can help smooth and firm the skin, diminish the appearance of fine lines, and soften deeper wrinkles. Of course, you can’t avoid skin aging completely—but incorporating glycolic acid into your routine can help promote a more youthful appearance.

4. Reduction of dark spots

You can use glycolic acid for dark spots, too. If your skin looks uneven due to the presence of stubborn brown, gray, or reddish marks, consider adding a glycolic acid serum or moisturizer to your routine. According to the American Academy of Dermatology (AAD), this powerful AHA can help resurface your skin, promoting a more even-looking complexion over time.

5. More hydrated skin

Some research suggests that glycolic acid can help hydrate the skin, making it an appealing exfoliant for those prone to dryness. Still, it’s best not to rely on glycolic acid alone to keep your skin hydrated—moisturizing twice daily is still a must (regardless of your skin type).

What Are the Risks of Glycolic Acid?

Like any powerful skincare ingredient, it’s important to understand what could go wrong before you dive in. While the glycolic acid benefits are impressive, overuse or misuse can lead to irritation and other unwanted effects. Here are two things to look out for when using glycolic acid.

Redness and irritation

Like all actives, using glycolic acid on your face can cause irritation, especially at higher concentrations. Redness, stinging, or light peeling are common when starting or using it too often. Starting with a low concentration and using it a few times per week helps minimize discomfort.

Increased sun sensitivity

According to the United States Food and Drug Administration (FDA), chemical exfoliants, including glycolic acid, can increase your skin’s sensitivity to sunlight. To protect your skin from unintentional burns or sun damage, be sure to wear a broad-spectrum sunscreen with an SPF of at least 15 every day. Keep in mind that for lasting protection, you’ll want to reapply your sunscreen at least every two hours (more frequently if you’re sweating or swimming). Need a recommendation? We love the L’Oréal Paris RevitaLift Triple Power Moisturizer with SPF 30.

How To Use Glycolic Acid in Your Skincare Routine

Getting all the glycolic acid benefits means using it thoughtfully and with care. The right approach can maximize the ingredient’s benefits while avoiding irritation, making it easier to maintain a healthy, glowing complexion. Here’s how to integrate it into your day-to-day routine the smart way.

Start with a low concentration

When introducing a glycolic acid serum or toner to your routine for the first time, follow a less is more approach. Begin with a low concentration two to three times a week and see how your skin reacts. If it tolerates well, you can gradually work your way up to a higher-concentration product.

Can you use glycolic acid daily?

Whether or not you can use glycolic acid every day depends on the product you’re using, your skin type, and the rest of your routine. Gentler products, like cleansers, can often be used daily, while more powerful glycolic acid serums may require a less frequent application. Since overexfoliating can damage your skin barrier and cause irritation, it’s extra important to be mindful in your approach. We recommend reading instructions on the product you’re using for guidance, and if you’re still unsure, consult your dermatologist for professional advice.

Always wear sunscreen

We mentioned it above, but it bears repeating: You should always wear sunscreen when using a product with glycolic acid, even if you use said product at night. For extra protection, take other sun-safety measures, too: Avoid direct sunlight at midday, stick to the shade when possible, and cover exposed skin with clothing or accessories (a wide-brimmed sunhat is chic and functional).
