Salicylic acid is a topical medication that comes in different strengths to treat a variety of skin conditions, including acne, warts, psoriasis, and dandruff. It's available in different formulations, such as cleanser, shampoo, body and face wash, and cream. Some salicylic acid products are available by prescription only. OTC topical salicylic acid can typically be used for a limited time during pregnancy, but you should check in with your provider before you start. Side effects of salicylic acid include skin irritation, dry skin, and itching.
Salicylic acid is an exfoliating agent. It breaks down the outer layer of your skin and slough off dead skin cells. This helps to treat conditions with abnormally thickened skin, such as calluses, corns, psoriasis, dandruff, and warts. It also can treat acne by helping softening the skin and unclogging pores.

It's best to avoid using salicylic acid and retinol together unless your provider or dermatologist gives you specific direction to do so. Retinol is topical form of vitamin A that's found in many anti-aging OTC skin care products. Both salicylic acid and retinol are known to cause skin irritation and using these products together can worsen skin-related side effects, such as peeling and dry skin.
Like salicylic acid, benzoyl peroxide is a topical acne medication. While it's possible to use benzoyl peroxide together with salicylic acid, you should check with your skin provider before doing so. This is because using both products together can worsen side effects, such as dry skin and skin irritation. If you do use both products, the American Academy of Dermatology Association recommends to start out with one acne treatment, and if you don't see improvement after 4-6 weeks you can add on a different medication. Your provider can help you decide the best acne treatment options for you.
Salicylic acid isn't a first-choice option for acne because it hasn't been as well-studied as other treatment options. But providers might still recommend it for certain types of acne. Let your provider know if you're looking for medications for acne and they can help you come up with the best treatment plan depending the cause and symptoms.
Salicylic acid hasn't been well-studied in human pregnancy. But the American College of Obstetricians and Gynecologists (ACOG) says over-the-counter products containing salicylic acid (which ranges from salicylic acid 0.5% to 2%) can be used during pregnancy. To be safe, your provider might only recommend it for a short period of time. Check in with your healthcare provider before using salicylic acid during pregnancy.
Yes, salicylic acid is classified under a group of ingredients known as beta hydroxy acids (BHAs). BHAs help remove dead skin cells and can improve skin texture.
Depending on the dosage form and condition you are treating, salicylic acid can take many weeks or months to work, but you might see improvements sooner. For acne, it could take 4 to 6 weeks to see improvement in your skin. If you're treating a wart, it could take up to 12 weeks to cure it with salicylic acid. If you're not sure how long you should use salicylic acid, ask your pharmacist or healthcare provider.
The amount of time you should use salicylic acid depends on what you're using it for and which product you're using. Since there are many different products that contain salicylic acid, make sure to follow the instructions on the packaging or from your provider. For some conditions like acne, it's usually recommended to use salicylic acid 1-3 times a day. But for other conditions, like dandruff, you might use the shampoo formula at least twice a week. Keep in mind that skin dryness and irritation can occur with some forms, and these side effects can worsen if you use salicylic acid too often. If you start experiencing bothersome side effects, check the product label to see if you should be using it less often or contact your provider.
Salicylic acid can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Because salicylic acid works by breaking down the skin, it can cause dry skin, which can crack more easily. This can lead to infections, especially in people with diabetes or conditions causing poor blood flow. People with diabetes are more likely to not feel when they have an open cut. In addition, diabetes or poor blood flow can cause longer healing times, which could also lead to an infection. If you have diabetes or a condition with poor blood flow, talk to your provider before using salicylic acid to make sure it is safe for you.
Using salicylic acid in children or teenagers could lead to a rare, life-threatening condition called Reye's syndrome where liver damage and brain swelling occur. Let your provider know if your child experiences diarrhea, vomiting, or unusually low energy. Get medical help right away if your child experiences confusion, loss of consciousness, or a seizure. The risk is higher in children and teenagers who have viral infections and the use of salicylic acid should be avoided.
It's important to only use salicylic acid in the affected areas. Applying this medication over larger areas of your skin can cause your body to absorb too much of the medication. This can lead to a life-threatening side effect called salicylate toxicity. Symptoms include nausea, vomiting, dizziness, loss of hearing, ringing in the ears, tiredness, fast breathing, diarrhea, and mental health conditions. Let your provider know if you have any of these symptoms above after taking salicylic acid.
