The 10 Best Salicylic Acid Serums for Acne, Blackheads, and Beyond

Why it’s worth it: For a budget-friendly option, Dr. Bowles recommends the Beta Hydroxy Acid Serum from the Inkey range. The formula contains 2% salicylic acid to help unclog pores and reduce excess oil, balanced with 1% hyaluronic acid to keep skin hydrated and comfortable. Its ultra-lightweight texture absorbs quickly without stickiness, and just a few drops patted onto the skin are enough to target blemishes, blackheads, and congestion on all skin types.
Frequently Asked Questions
Who should use salicylic acid serum?
Salicylic acid serums are especially beneficial for people with oily, acne-prone, or combination skin, as well as those who struggle with blackheads, clogged pores, or breakouts in the T-zone, says Dr. Bowles. “Because salicylic acid is oil-soluble, it penetrates deep into pores, making it ideal for congestion-related acne.” Although some patients with sensitive skin cannot tolerate salicylic acid, they should start with a low concentration (like 0.5%) and gradually add the active to their system, and choose a formulation with mild ingredients (hi, green tea). “It may not be the best way to choose skin barriers that are very dry, prone to eczema, or vulnerable unless directed by a dermatologist,” warns Dr. Bowles.
What concentration of salicylic acid should you look for?
Dr. Bowles says most over-the-counter salicylic acid products contain between 0.5% and 2%, with 2% being the limit allowed in the US. “For most people, 2% is effective and well tolerated, but higher percentages don’t necessarily mean better results,” he explains. The product vehicle, whether it’s a serum, toner, or cleanser, is usually as important as a percentage. “Using the right composition at the right frequency is more important than chasing high numbers,” he said. In fact, lower concentrations may work better for sensitive or dry skin types if used regularly.
What other ingredients should you look for in salicylic acid serums?
Dr. Bowles always encourages his patients to look for ingredients that reduce irritation and strengthen the skin barrier. For example, “niacinamide helps calm redness and regulate oil production, making it a good combination with salicylic acid,” she said. “Ceramides and panthenol support barrier repair, which is especially important if you use exfoliating acids regularly, and antioxidants like green tea extract can help reduce inflammation and protect the skin.” Look for hyaluronic acid and glycerin to absorb moisture.

How we test and review products
Before reviewing any cosmetics, we ask several questions: What ingredients are in them? Does the brand offer a wide range of colors that include consumers with all skin tones and undertones? Is it safe for students with sensitive skin or contact lens wearers? Is it on the affordable side or more of a splurge? Is its packaging consciously designed or is it unnecessarily wasteful?
To review the best lip and cheek products, we enlisted the help of many editors, writers, contributors, makeup chemists, and professional makeup artists to review the products. This ensures that our test base includes different skin tones, genders, and skin conditions. We considered each product’s performance across four main categories: ingredients, aging and longevity, packaging, and inclusiveness.
