What is salicylic acid?
A type of beta hydroxy acid (BHA), salicylic acid is known for being a chemical exfoliant and acne treatment, making it ideal for oily or acne-prone skin, says Dr. Connie Yang, board-certified dermatologist and member of Dermstore’s Medical Advisory board.
Modern skincare formulas typically use salicylic acid that is either synthesized in a lab or extracted from plants like willow bark and sweet birch. While its lab version is known for its precise concentration, stability, and consistency, salicylic acid from natural sources tends to be gentler on the skin and can be a good option for those with sensitive skin.
What Does Salicylic Acid Do?
Salicylic acid is a true powerhouse when it comes to managing and preventing acne, improving skin clarity, and fading blemishes. It’s a multitasking exfoliant that works both on the outer layer of the skin and within pores. On the skin’s surface, Dr. Yang says salicylic acid “can help shed outer layers of dead skin and smooth out texture,” helping fade post-acne marks and improve tone over time.
As a BHA, it shares many of its functions and benefits with AHAs or alpha hydroxy acids (like glycolic acid and lactic acid). Their main difference? Salicylic acid is oil-soluble while AHAs dissolve in water. “This allows salicylic acid to penetrate deeply into the pores to help dissolve dead skin cells and break down sebum,” explains Dr. Yang. In doing so, salicylic acid targets acne right at the source, diving deep into your pores and clearing out the gunk that’s fueling the breakout. Plus, it’s antibacterial, which means it helps eliminate and prevent the spread of acne-causing bacteria.
On top of that, salicylic acid also has anti-inflammatory properties that can help reduce redness and swelling, especially with big, painful pimples, says Dr. Yang. In other words, not only does it help clear acne, it also calms it down while speeding up the skin’s natural healing process.
Benefits of Salicylic Acid
Being the well-rounded ingredient that it is, salicylic acid offers a long list of benefits that go beyond treating pimples. According to Dr. Yang, here are the top reasons that make salicylic a skincare staple:
- Helps unclog pores by dissolving the glue that binds dead skin cells, allowing them to shed faster
Clears blackheads and whiteheads by decongesting pores Reduces sebum production for oily skin types - Brightens and evens complexion by improving tone and texture over time
- Treats keratosis pilaris or “chicken skin”
- Reduces dandruff when used on the scalp
How to Use Salicylic Acid in Your Skincare Routine
Salicylic acid for skin can be found in virtually every type of product—from cleansers and toners to serums and spot treatments—and picking out which one to add to your skincare arsenal depends on your needs.
If your goal is to manage existing breakouts and speed up their departure, go for serums and targeted treatments. If you’re beefing up your routine to prevent future breakouts and maintain skin clarity, then exfoliating cleansers and toners are your best bets. Just remember: the same rules you follow whenever you introduce your skin to a heavy-hitting active also apply to salicylic acid. In other words, start low and slow.
“I recommend incorporating salicylic acid into your routine gradually to minimize the risk of irritation,” says Dr. Yang. Start with once or twice weekly application to avoid unwanted reactions like excessive dryness, especially if you have sensitive skin. In the mornings, always use SPF as salicylic acid can make your skin more susceptible to sun damage.
Love layering or mixing and matching actives? With salicylic acid, Dr. Yang says it’s best to proceed with caution. Using several workhorse ingredients at once can be too much for your skin and may even do more harm than good. And that’s the last thing you want if you’re already dealing with stubborn acne. If you want to play it extra safe, talk to your dermatologist about how to use salicylic acid for skin to prevent overwhelming your complexion.
Salicylic Acid vs. Benzoyl Peroxide: How They Differ?
Benzoyl peroxide and salicylic acid are both top-tier acne ingredients, but they each have a different way of getting things done. Salicylic acid for skin is a chemical exfoliant, and although it has calming and bacteria-fighting effects, its true strengths lie in preventing clogged pores and speeding up cell turnover through exfoliation.
On the other hand, benzoyl peroxide is a no-nonsense germ fighter. It goes straight for acne-causing bacteria that contribute to inflamed pimples. It works fast too. It calms and dries out existing acne, helping them heal faster. Although it does its job a little too well sometimes it causes over-drying, flaking, and redness, especially if used in higher concentrations or without the right buffer or moisturizer.
Can You Use Salicylic Acid with Retinol?
Technically, you can—but Dr. Yang would rather that you don’t. “I recommend avoiding layering the two ingredients as it increases the risk of irritation. The exception being specific products that contain both ingredients as they are formulated to be used together at once.” If you must have both, make sure to use them on alternate nights and that you have a hydrating moisturizer and serum ready to counter excessive dryness and irritation.
Is Salicylic Acid Safe for All Skin Types?
Salicylic acid for skin is generally well-tolerated by most skin types. However, we also know that no single skincare ingredient comes with zero unwanted reactions. Nor is there a one-size-fits-all solution. “As with any chemical exfoliant, it can cause irritation if used too frequently or alongside too many actives. It can also make skin more photosensitive, so it’s important to use sunscreen daily,” explains Dr. Yang.
If your skin tends to be on the dry side or highly reactive, you may want to take your time with salicylic acid. “If you have dry or sensitive skin, salicylic acid can be irritating, especially at higher concentrations,” explains Dr. Yang. Your best bet? A sensitive skin-friendly formula with lower concentrations of salicylic acid (less than two percent), so you can reap its top benefits without putting your skin on the line.
That said, those dealing with inflammatory skin conditions like rosacea may need to skip salicylic acid altogether. Or, at the very least, use it with extreme caution and under the guidance of a dermatologist.

FAQs
Do dermatologists recommend salicylic acid?
Absolutely. Salicylic acid is one of the most derm-trusted ingredients for managing and preventing acne, says Dr. Yang. “I recommend salicylic acid all the time to my patients with comedonal acne or those who struggle with oily skin.”
Does salicylic acid cause purging?
According to Dr. Yang, salicylic acid can cause purging, although it’s not as common as with retinoids. “Salicylic acid does increase exfoliation and speed up cell turnover. It clears out clogged pores, which can cause dormant pimples or microcomedones to surface more quickly. This may look like more breakouts, but it’s actually just part of the skin-clearing process,” she explains.
Does salicylic acid help with blackheads?
Yes, it does! In fact, it’s one of the most effective ingredients for minimizing blackheads, and with consistent use, it prevents new ones from forming. Because it’s oil soluble, salicylic acid can go deeper into the pores to remove trapped gunk, dead skin cells, and oil that can lead to blockages and blackheads.
Can salicylic acid help with acne scars?
If you’re mostly dealing with post-inflammatory hyperpigmentation and acne scars, then salicylic acid is your wingman. “It’s an exfoliant, so it can help gradually smooth out skin texture and lighten dark spots from acne,” says Dr. Yang. And although salicylic acid alone won’t be enough to fade deep scarring and discoloration, pairing it with niacinamide can enhance results.
What are differences between salicylic acid and glycolic acid?
Glycolic acid is an AHA, which means it is water-soluble and can’t penetrate into the pores as deeply as salicylic acid can, explains Dr. Yang. As BHAs like salicylic acid dive deep and work on dissolving deep-seated dirt, oil, and debris, glycolic acid exfoliates the surface of the skin. It’s ideal for brightening dull skin, blurring fine lines, and improving discoloration.
The Bottom Line
Salicylic acid for skin is neither hype nor an overnight miracle worker. What it is, instead, is an ingredient that delivers steady, targeted results that actually last. A proven powerhouse, it tackles acne, blackheads, post-inflammatory hyperpigmentation, and texture and tonal issues, especially in oily or acne-prone skin. Unlike AHAs, salicylic acid is oil-soluble and can penetrate pores better. It clears congestion, dissolves excess oil and debris, and reduces the chance of future breakouts. It is a reliable foundation in your acne routine, especially when used consistently and correctly. Paired with expert-backed advice and the right supporting ingredients, salicylic acid can help you achieve clearer, smoother skin with confidence.
