Side effects of salicylic acid include burning, redness and general skin irritation. To help reduce the risk of side effects, start by applying a salicylic acid treatment for a just a few days a week. Salicylic acid can also cause your skin to become more sensitive to the sun so use a non-oily sunscreen during the day.
Although salicylic acid is considered safe overall, it may cause skin irritation when first starting. It may also remove too much oil, resulting in dryness and potential irritation. Other potential side effects include: skin tingling or stinging.
For example, salicylic acid, which works to unclog pores, is also a “mild chemical irritant.” Kathleen Suozzi, a dermatologic surgeon at Yale School of Medicine explains that this means salicylic acid also works as a drying agent and can cause skin redness and flaking if used too much.
While the use of household salicylic acid products at low concentrations is generally considered safe, in high concentrations, salicylic acid is capable of causing moderate chemical burns. If ingested, this chemical can also lead to dangerous intoxication.
Treated areas take about seven to 14 days to heal after a medium chemical peel, but redness might last for months. After a deep chemical peel, you'll experience severe redness and swelling.
“When you apply a higher dosage than skin is used to, salicylic acid disrupts your skin's barrier, creating microscopic cracks that cause skin to lose moisture and become irritated and inflamed — hence the red, itchy, flakiness that's so often associated with acne treatments,” Dr. Zeichner adds.
Irritation and Peeling
You could develop painful, pus-filled blisters and severe damage to your skin. The bottom line — if you notice redness, irritation and peeling, stop using the problematic product.
Acne treatments — especially those that contain active ingredients like benzoyl peroxide and salicylic acid — are drying and a bit harsh on your skin. If you use too many treatments at the same time, your skin may become irritated, and you may actually suffer more breakouts as a result.
"If salicylic acid is an ingredient in your cleanser, it is fine to use it every day." However, if you are using an exfoliant that salicylic acid in the formula, Dr. Hu advises only using the product three times per week, to avoid over-exfoliating the skin and drying it out.
Signs and symptoms of chemical burns include the following: Redness, irritation, or burning at the site of contact. Pain or numbness at the site of contact. Formation of blisters or black dead skin at the contact site.

You get the maximum benefit when you adjust your skin to start using it twice a day. But, if you are sensitive to salicylic acid and using it up regularly left your skin dry, red, and peeling, then use it as a toner and leave it up for up to 30 seconds and then rinse off.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Do you apply salicylic acid before or after moisturiser? Generally speaking, the most potent skin products containing salicylic acid are those such as serums, spot treatments and cleansers, all of which are applied before moisturisers.
Wipe the pad over the affected areas. Do not rinse off medicine after treatment.
Skin purging typically looks like tiny red bumps on the skin that are painful to touch. They are often accompanied by whiteheads or blackheads. It can also cause your skin to become flaky. The flare ups caused by purging have a shorter lifespan than a breakout.
When using salicylic acid or other acne treatments, it may take 6-8 weeks to start noticing results. Anyone who does not see an improvement in their acne after this time may wish to contact a doctor or dermatologist for advice on alternative treatment options.
After a few weeks of purging, your skin and acne will have noticeably improved. Breaking out is when your skin is reacting because it is sensitive to something in the new product. You may get spots in a new area that you don't typically and they take longer to go away.
“You can use a salicylic acid–based cleanser in the morning to unclog pores and avoid acne and a glycolic acid–based cleanser at night to exfoliate your skin and get rid of dead skin cells,” notes Jailman.
Salicylic Acid also acts as an inflammatory agent, soothing inflammations and pimples with ease. It has naturally soothing properties and it might work for sensitive skin too.
Signs of over-exfoliation
“The skin appears as if it has a radiant shine. However, it is in fact very dry and exposed.” And overexposure can devolve into painful cracking and peeling, explains Geria. For reference, a healthy glow will always look plump and moisturized, not dry, thin, or waxy.
Salicylic acid topical can cause a rare but serious allergic reaction or severe skin irritation. These reactions may occur just a few minutes after you apply the medicine, or within a day or longer afterward.
Day or Night
One of the most popular Beta Hydroxy Acids (BHAs), salicylic acid is an ultra-common ingredient in many acne fighting products, and is well-suited for both day and night.
