When considering treatments for acne-prone skin, two popular options often come into focus: glycolic acid and salicylic acid. Both are known for their exfoliating properties, leaving skin looking clearer and brighter. While they share some similarities, there are distinct differences between the two. The most effective treatment will ultimately depend on an individual’s unique skin type.
In this post, I delve deeper into the benefits of glycolic acid and salicylic acid to determine which one is best suited for acne-prone skin.
Glycolic Acid vs Salicylic Acid for Acne
AHAs Vs BHAs
While both glycolic acid (AHA) and salicylic acid (BHA) are chemical exfoliants, they differ significantly in their chemical structure, origin, and properties. Glycolic acid is a water-soluble AHA derived from plant sources like sugar cane or grapes, whereas salicylic acid is an oil-soluble BHA typically sourced from willow bark.
The latter’s smaller molecular size allows it to penetrate deeper into the skin, making it more effective at clearing blocked pores, albeit with a higher risk of irritation. In contrast, glycolic acid’s larger molecules are water-soluble and work best at breaking down dead skin cells on the surface, exposing brighter skin beneath. Unlike BHAs, AHAs cannot penetrate beyond the skin’s outer layer and won’t unclog blockages in the same manner.
Glycolic Acid Benefits
Glycolic acid, an alpha hydroxy acid derived from sugar cane, boasts a unique profile as the smallest AHA molecule with exceptional exfoliating capabilities. By efficiently removing dead skin cells from the surface of the skin, it stimulates cell turnover and reveals bright, healthy, and radiant new skin that is clear and remarkably smooth.
This remarkable property makes glycolic acid an integral component in anti-aging skincare products, where it excels at diminishing fine lines and wrinkles, while also addressing inflammation, acne-causing bacteria, and uneven skin tone. Moreover, its efficacy extends to reducing hyperpigmentation, dark spots caused by sun exposure, and minimizing the appearance of acne scars, ultimately preventing new blemishes or blackheads from emerging.
Salicylic Acid Benefits
Salicylic acid, derived from the extract of willow bark, is a beta hydroxy acid that boasts potent anti-inflammatory properties. These properties allow it to effectively mitigate the redness and swelling often associated with acne breakouts. Beyond its calming effects, salicylic acid also plays a crucial role in skin health by removing dead skin cells and exfoliating at multiple levels, making it a more effective impurity remover compared to glycolic acid.
Its unique properties make it particularly well-suited for individuals with oily or acne-prone skin, as it can break down sebum and unclog pores, thereby preventing future breakouts while also boasting antimicrobial properties that help prevent infection.
Glycolic Acid vs Salicylic
Acne treatment often involves the use of alpha-hydroxy acids (AHAs) like glycolic acid and beta-hydroxy acid (BHA) such as salicylic acid. Both of these ingredients are effective in addressing acne, primarily by exfoliating the skin and removing blockages that contribute to acne formation. Glycolic acid is a milder AHA that leaves the skin looking brighter and smoother, whereas salicylic acid can penetrate deeper into pores to clear away blackheads and eliminate acne-causing bacteria.
When selecting between these two ingredients, it’s essential to consider your skin type. Glycolic acid is better suited for dry, acne-prone skin or skin with fine lines and wrinkles. This AHA draws moisture and hydration to the skin, preventing new lines from developing and increasing the absorption of other skincare products. Due to its surface-level action, glycolic acid may also be beneficial for sensitive skin types.
If you’re dealing with raised acne scars or dark marks, glycolic acid is an excellent choice for smoothing out the skin’s surface and achieving a more even tone. On the other hand, salicylic acid is ideal for oily, acne-prone skin. As it’s oil-soluble, this BHA can penetrate deep into pores to remove dead skin cells, excess oils, and bacteria that causes acne breakouts.
Salicylic acid is also more effective at reducing inflammation, which can help alleviate the redness and swelling associated with acne. If you have active acne lesions, salicylic acid may help clear them up faster than glycolic acid since it can unblock pores at a deeper level. For those dealing with a combination of active blemishes and old scars, incorporating both glycolic and salicylic acid into your skincare routine and using them at different times may be beneficial.
Using Salicylic Acid and Glycolic Acid Together
When incorporating both glycolic and salicylic acid into your skincare routine, you can alternate between using them individually or in combination. For instance, apply a leave-on glycolic exfoliant every other night while using a daily salicylic cleanser or gel wash. You can also blend the acids with your moisturizer by applying a serum underneath. The synergistic effect of both acids on removing dead skin cells can yield remarkable results, such as clearer and smoother skin.
However, it’s crucial to avoid over-stripping the skin by using them too frequently, which may lead to dryness, tightness, or irritation. To mitigate this risk, consider starting with a weekly glycollic acid application and gradually introducing salicylic-based products. Remember that combining these acids can increase your skin’s sensitivity to the sun, making it essential to wear a broad-spectrum SPF with at least an SPF of 30 or higher daily.

The Ordinary AHA 30% + BHA 2% Peeling Solution
The Ordinary AHA 30% + BHA 2% Peeling Solution is a multi-action formula that combines the exfoliating power of alpha hydroxy acids (AHAs) and beta hydroxy acid (BHA). The blend includes 30% AHAs, comprising glycolic acid, lactic acid, tartaric acid, and citric acid, as well as 2% salicylic acid.

This unique combination deeply hydrates the skin while effectively exfoliating the surface and addressing pore congestion. The formula’s gentle nature makes it an excellent choice for those seeking to improve their skin tone and texture without irritation. The Tasmanian pepperberry component, in particular, helps mitigate any potential discomfort caused by the acid content.
This solution is particularly well-suited for individuals struggling with dark spots resulting from acne or sun damage, as it smooths out the skin’s surface and gradually fades hyperpigmentation. With its high concentration of AHAs, this product leaves the top layer of the skin looking brighter, healthier, and more refined.

Alpha-H Liquid Gold
After being recommended by Ruth Crilly of A Model Recommends, I tried Alpha H Liquid Gold, a glycolic acid toner that’s often referred to as a serum. While it can be used in various ways, I’ve found that applying it with a cotton pad and leaving it on overnight yields the best results. The clear liquid formula allows for easy absorption into the skin.
When used alone, without moisturiser, the product is most effective at revitalising dull complexions and reducing the appearance of fine lines, blackheads, blemishes, or acne scars. While you can use Alpha H Liquid Gold every other night, I’ve found that once a week is sufficient for my skin type. In contrast to glycolic acid peels, this product is much gentler and, when used correctly, won’t cause any redness or irritation.
The INKEY List 2% Salicylic Acid Cleanser
One of my top recommendations for controlling excess oil is The INKEY List’s 2% Salicylic Acid Cleanser. This effective face wash not only removes impurities but also balances skin health by regulating sebum production.

This potent combination is further enhanced by the presence of glycolic acid, salicylic acid, mandelic acid, and lactic acid.
As a result, users can expect an improvement in skin texture and a noticeable smoothening effect. However, it’s essential to exercise restraint when using these pads, as overindulgence may lead to skin irritation. For those seeking to tackle acne and scarring, the Nip+Fab Glycolic Fix Extreme Night Pads make for an excellent choice, but it’s crucial to prioritize careful usage to avoid adverse reactions.
