Can You Use Glycolic Acid and Retinol Together?

Glycolic acid and retinol are two of the most popular skincare actives due to their effectiveness and ability to improve the look of your skin. Glycolic acid is an alpha hydroxy acid (AHA) that exfoliates dead skin cells on the surface of your skin. Retinol is a vitamin A derivative that helps reduce fine lines and wrinkles by increasing collagen production.

Since they’re both great at fighting signs of aging, can you use glycolic acid and retinol together in the same skincare routine?

Due to the chemical composition and potency of glycolic acid and retinol, you run the risk of irritation and a reduction in effectiveness if you use them at the same time. In general, glycolic acid and retinol should not be used at the same time unless you are using a product specially formulated with both ingredients or if you have a skin type that can withstand strong actives.

Let’s look at the factors that determine if glycolic acid and retinol can be used together in the same skincare routine.

Can You Use Glycolic Acid and Retinol Together?

First, let’s talk chemical composition and pH. PH is the measure of the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. The skin’s natural pH tends to average about 4.7, which is slightly acidic.

While retinol tends to work best on your skin at a more neutral pH between 5.5 and 6, exfoliating acids like glycolic acid works best at an acidic pH between 3.0 and 4.0. So mixing pH levels could reduce the effectiveness of both actives.

Another reason that you may want to avoid using glycolic acid and retinol is that they both can cause irritation in some people, so using them together could increase irritation, dryness, redness, flaking, and peeling.

However, there are products that contain both glycolic acid and retinol that have been specially formulated to reduce the irritation that would normally occur from using these two ingredients simultaneously.

That being said, if you don’t have sensitive skin and can tolerate strong actives, you might be able to use the two together at lower concentrations. This study demonstrated that retinoic acid and glycolic acid used together are effective at treating acne scars.

THE TAKEAWAY: If you don’t have sensitive skin and are using glycolic acid at lower concentrations, you may be able to use retinol with it. However, if you have sensitive skin, it’s best to choose only one strong active at a time in your skincare routine.

How to Use Glycolic Acid and Retinol in Your Skincare Routine

Consider using glycolic acid in the morning and your retinol product in the evening since both ingredients can cause irritation and have reduced effectiveness when used together due to the variance in their pHs.

Or, you can alternate days that you use glycolic acid and retinol in your skincare routine.

If your skin is not sensitive and can withstand using glycolic acid and retinol together, start with low concentrations of both. After cleansing and toning your skin in your PM skincare routine, apply glycolic acid (or retinol if it has a thinner texture) and then wait at least 30 minutes before using retinol to allow your skin’s pH to normalize. This will help improve the effectiveness of both products.

Make sure to follow with a hydrating moisturizer, especially if you are using both actives at the same time since glycolic acid and retinol can dehydrate your skin.

Also, don’t forget to apply a broad-spectrum sunscreen daily to protect your skin since glycolic acid and retinol can make your skin more sensitive to the sun.

The Benefits of Glycolic Acid

Glycolic Acid Products from The Ordinary, Mario Badescu, CeraVe and Paula's Choice

Derived from sugar cane, glycolic acid is an alpha hydroxy acid (AHA). AHAs are exfoliating acids that remove dead skin cells on the skin’s surface, which helps to create softer, smoother, and brighter skin. Due to its small molecule size, glycolic acid can reach deeper than other AHAs making it more effective.

Glycolic acid increases cell turnover, which smoothes the look of fine lines and wrinkles and skin dullness. It also stimulates the production of collagen, so over time, glycolic acid helps improve skin firmness and elasticity.

Glycolic acid helps to fade hyperpigmentation, dark spots, and uneven skin tone. It can also help to reduce the look of acne scars from post-inflammatory hyperpigmentation.

Glycolic acid can help treat acne, although not as proven as benzoyl peroxide or the beta-hydroxy acid, salicylic acid.

Unfortunately, due to its small molecule size, glycolic acid may also cause irritation and redness in some skin types, especially those with sensitive skin. In that case, you may wish to try AHAs with a larger molecule size like lactic acid or mandelic acid.

NOTE: Different concentrations of glycolic acid will have different levels of exfoliation, so if you are new to AHAs, consider starting with a lower concentration and slowly work your way up. AHAs make your skin more sensitive to the sun, so regardless of the concentration of glycolic acid that you use, you should always apply a broad-spectrum sunscreen with an SPF of 30 or higher while using glycolic acid and other AHAs.

The Benefits of Retinol

Retinol Products from Olay, CeraVe, The Ordinary and RoC

Retinol is a form of vitamin A that is converted to its active form, retinoic acid, in the skin. It reduces the appearance of fine lines and wrinkles by increasing collagen production and cell turnover in your skin. It also helps to fade hyperpigmentation, sunspots, and other discoloration.

Retinol increases epidermal thickness and even alters collagen gene and protein expression in the skin, providing an anti-aging effect.

Retinoids also balance sebum (oil) production and help prevent the formation of comedones. Comedones are clogged pores that can become blemishes like whiteheads or blackheads. Retinol also has anti-inflammatory benefits, which calm inflamed acne-prone skin.

It’s important to note that you should use sun protection when using retinol, like glycolic acid, since it makes your skin more sensitive to harmful UV rays. It is best to use retinol and other retinoids in your evening skincare routine.

Retinol can be less irritating than stronger forms of vitamin A. However, irritation is still possible and may increase with higher retinol concentrations or in people who have sensitive skin. If your skin gets too irritated from a retinol product, consider using it once every other day, every third day, or even once a week to minimize irritation.

Final Thoughts on Using Glycolic Acid and Retinol Together

Glycolic acid and retinol are two of the few over-the-counter actives powerful enough to create visible improvements in your skin. They’re both excellent at smoothing, brightening, and improving skin radiance.

Whether you choose to use one or both, just be sure to start slow with each, as glycolic acid and retinol can cause irritation. If you experience dry, flaking skin try applying a moisturizer or hydrating serum before applying your glycolic acid or retinol product.

For the best results, avoid using glycolic acid and retinol together on the same day, especially if you have sensitive skin. Instead, use them at different times of the day or different days of the week. And be sure to wear sunscreen when using glycolic acid and retinol because they make your skin more sun-sensitive.
