Can You Mix Glycolic Acid and Salicylic Acid? A Comprehensive Guide

Glycolic acid and salicylic acid are two of the most popular ingredients in skincare products. Both acids are known for their ability to exfoliate the skin and improve the overall appearance of the skin. However, many people wonder if it’s safe to use both acids together. In this article, we’ll explore whether you can use glycolic acid with salicylic acid.

What is glycolic acid?

Glycolic acid is a type of alpha-hydroxy acid (AHA) that is derived from sugar cane. It’s a water-soluble acid that works by dissolving the bonds between dead skin cells, allowing them to be easily removed from the skin’s surface. This exfoliating action helps to reveal newer, fresher skin cells underneath, resulting in smoother, brighter, and more even-toned skin.

What is salicylic acid?

Salicylic acid is a type of beta-hydroxy acid (BHA) that is derived from willow bark. It’s oil-soluble and can penetrate deep into the pores of the skin, where it works to dissolve excess oil, dirt, and dead skin cells. This makes it a great ingredient for treating acne-prone skin, as it helps to unclog pores and prevent future breakouts.

Can you use glycolic acid with salicylic acid?

The short answer is yes, you can use glycolic acid with salicylic acid. In fact, many skincare brands offer products that contain both acids to provide a more comprehensive exfoliating and acne-fighting treatment.

However, it’s important to use caution when combining acids, as over-exfoliation can lead to irritation, redness, and dryness. It’s best to start slowly by introducing one acid at a time into your skincare routine, and gradually building up to using both at the same time.

How to use glycolic acid and salicylic acid together

If you want to use glycolic acid and salicylic acid together, there are a few things to keep in mind:

• Start by using each acid separately, to see how your skin reacts to each one.
• Introduce one acid into your routine first, and use it for a week or two before adding the other acid.
• Use glycolic acid in the morning and salicylic acid at night, to avoid over-exfoliating the skin.
• Start with a low concentration of each acid and gradually increase the concentration over time.
• Be sure to use a moisturizer to help soothe and hydrate the skin after using acids.

The Ordinary offers two popular products that contain both glycolic acid and salicylic acid: their Glycolic Acid 7% Toning Solution and their Salicylic Acid 2% Masque.

Conclusion

In conclusion, you can use glycolic acid with salicylic acid, but it’s important to use caution when combining acids. Start slowly, and gradually build up to using both acids together. Be sure to listen to your skin, and if you experience any irritation or dryness, scale back your use of acids. Remember to always use a moisturizer to help soothe and hydrate the skin after exfoliating with acids.
