Glycolic Acid vs Salicylic Acid: Which One Does Your Skin Really Need?
Exfoliating acids have become increasingly popular in skincare for good reason. They can help refine uneven skin texture, brighten dullness, clear clogged pores, and promote healthier-looking skin. Among the most common options are AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids), with glycolic acid and salicylic acid being two of the most well-known choices.
If you're unsure whether glycolic acid or salicylic acid is better suited for your needs, this guide will help explain the key differences, the benefits of glycolic acid versus salicylic acid, and how to choose the right option based on your skin concerns.
What is Glycolic Acid (AHA)?
Glycolic acid is a type of alpha hydroxy acid derived from sugarcane1. It works on the surface of the skin by gently breaking the bonds between dead skin cells, allowing them to shed more easily. Over time, this helps reveal fresher, smoother, and more radiant-looking skin.
Thanks to its small molecular size, glycolic acid absorbs efficiently, making it one of the most effective AHAs for improving surface texture. It’s especially beneficial for those dealing with dryness, dullness, rough patches, or early signs of aging.
If you’re looking to restore a more even, glowing complexion, incorporating an AHA skincare product like our 8% AHA Gel Exfoliant can be a gentle yet effective way to smooth and revitalise your skin without unnecessary irritation.
What is Salicylic Acid (BHA)?
Salicylic acid is a beta hydroxy acid derived from willow bark2. Unlike AHAs, salicylic acid is oil-soluble, allowing it to penetrate deep into pores to break down excess oil, dead skin cells, and impurities. This makes it particularly effective for helping to clear clogged pores, reduce blackheads, and manage breakouts.
In addition to its deep-cleansing ability, salicylic acid offers natural anti-inflammatory benefits3, helping to calm redness and soothe irritation often associated with acne-prone skin.
For those struggling with oily skin, blackheads, or frequent blemishes, using a BHA skincare product like Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant can be a game-changer. Its gentle yet powerful formula helps unclog pores and smooth skin texture, making it suitable for regular use without causing unnecessary dryness.
How to Choose: Skin Type & Concerns
Choosing between glycolic acid and salicylic acid starts with understanding your skin’s current condition and goals.
If your skin feels dry, rough, or looks dull, an AHA glycolic acid product is likely the better option. Its surface-level exfoliation helps smooth texture and reveal a more luminous, even-toned complexion.
Meanwhile, those struggling with oily skin, blackheads, or visibly enlarged pores will benefit more from salicylic acid. Its ability to penetrate deep into pores helps clear congestion and regulate excess oil.
Whichever option you choose, it's important to introduce exfoliating acids slowly into your routine. Start by using them two to three times a week, then adjust based on how your skin responds. Always follow with a gentle moisturizer and broad-spectrum sunscreen during the day, as exfoliation can make your skin more vulnerable to sun sensitivity.
Can You Use AHA and BHA together?
It is possible to use both glycolic acid and salicylic acid in your skincare routine, but it’s important to introduce them thoughtfully.
Some people prefer alternating between an AHA and a BHA product on different days, while others apply them at different times — such as using salicylic acid in the morning and glycolic acid at night.
If you’re new to exfoliating acids, it’s best to start with just one to see how your skin responds. Layering both too quickly can increase the risk of dryness, sensitivity, or irritation.
Pay close attention to how your skin feels and adjust the frequency of use based on its tolerance.
Building up gradually gives your skin the chance to enjoy the benefits of both acids without becoming overwhelmed.
