Navigating the world of skincare acids can be overwhelming, especially when comparing two of the most talked-about ingredients: glycolic acid vs salicylic acid. Both offer well-documented benefits, but they work in very different ways. Understanding how they differ is key to choosing the right one for your skin type and concerns.
In this latest blog post, we explore the benefits of each, outline who they’re best suited for and explain how to use them effectively in your routine. We’ll also introduce some of allmedic’s medical-grade product options that combine the strengths of both acids for more targeted skincare results.
What Is Glycolic Acid?
Glycolic acid is a type of alpha-hydroxy acid (AHA), derived from sugar cane. It’s known for its ability to gently exfoliate the skin’s surface, removing dead skin cells to reveal a smoother, more even complexion.
As it has the smallest molecular size among AHAs, glycolic acid penetrates efficiently, stimulating cell turnover and improving the appearance of fine lines, texture and discolouration. It’s particularly helpful for dry, sun-damaged, or ageing skin types.

Understanding the difference between glycolic acid vs salicylic acid helps you tailor your skincare routine based on your skin's specific needs.
What Is Salicylic Acid?
Salicylic acid is a beta-hydroxy acid (BHA) that’s oil-soluble, meaning it can travel deep into the pores to dissolve excess sebum and dead skin cells. This makes it especially effective for acne-prone and oily skin, where clogged pores and breakouts are common.
In addition to its exfoliating effects, salicylic acid has soothing properties, helping to calm redness and inflammation often associated with blemishes and congested skin.Glycolic Acid vs. Salicylic Acid: What’s the Difference?
Although both acids are used for exfoliation, they function quite differently:
Feature | Glycolic Acid | Salicylic Acid |
---|---|---|
Acid Type | AHA (Alpha Hydroxy Acid) | BHA (Beta Hydroxy Acid) |
Solubility | Water-soluble | Oil-soluble |
Target | Surface exfoliation | Deep pore cleansing |
Best For | Dry, dull, textured, uneven skin | Oily, acne-prone, blackhead-prone skin |
Key Benefits | Brightens, refines, smooths | Clears pores, reduces breakouts |
How to Choose the Right Acid for Your Skin
The choice between glycolic acid and salicylic acid comes down to your skin’s condition and your specific goals.
- For dry or sun-damaged skin: Glycolic acid can help improve tone, texture and hydration by encouraging faster cell turnover.
- For oily or acne-prone skin: Salicylic acid excels at decongesting pores and reducing breakouts without over-drying.
- For combination skin or multiple concerns: Some medical-grade products combine both acids to offer surface-level and deep-pore exfoliation in one step.
Using them together can be effective, but it’s important to do so carefully. Start slowly, introduce one acid at a time and always follow up with SPF — both acids can increase your skin’s sensitivity to the sun.

Choosing between glycolic acid vs salicylic acid depends on whether you're targeting surface texture or deeper pore issues.

FAQs
What is the difference between glycolic acid and salicylic acid?
Glycolic acid is water-soluble and exfoliates the skin’s surface, while salicylic acid is oil-soluble and penetrates into pores. Each targets different skin concerns.
Is glycolic acid or salicylic acid better for acne-prone skin?
Salicylic acid is generally more effective for acne-prone skin as it clears excess oil and debris from inside the pores, helping reduce breakouts and blackheads.
Can I use glycolic acid and salicylic acid together?
Yes, but introduce them gradually. Using both can support surface exfoliation and pore clearing, especially when using a product that combines both ingredients.
Which acid is best for oily skin?
Salicylic acid is ideal for oily skin because it dissolves excess sebum, prevents clogged pores and reduces the likelihood of acne formation.
Should you use salicylic acid or glycolic acid for sensitive skin?
Sensitive skin types should start with lower concentrations. Salicylic acid may be better tolerated in small doses, while glycolic acid can be more irritating if overused.
