From Salicylic Acid to Sulfur: Discover 5 Common Acne-Fighting Ingredients

1. Salicylic Acid

Found in scrub, gel, and cleanser formulas—to name a few—salicylic acid is a common topical ingredient used to reduce the appearance of acne. Available in strengths up to 2 percent, this beta hydroxy acid works by exfoliating the skin, unclogging pores, and reducing the swelling and redness associated with pimples. Salicylic acid can dry out and irritate the skin, so it’s important to use it as directed.

2. Benzoyl Peroxide

Available in strengths up to 10 percent, benzoyl peroxide kills acne-causing bacteria and removes excess oil and built-up dead skin cells that can clog pores. Side effects include dryness, redness, and stinging, and it may take up to four to six weeks before seeing its effects. 

3. Alpha Hydroxy Acids

Like salicylic acid, alpha hydroxy acids (AHAs) exfoliate the skin by removing dead skin cells. The types most often found in acne-fighting formulas are glycolic acid and lactic acid. The FDA warns that using AHAs can make the skin more sensitive to sunlight, so try to use products containing these acids before bedtime and apply a broad-spectrum SPF in the morning.

4. Sulfur

Used often in targeted, leave-on formulas, sulfur reduces bacteria and unclogs pores. This ingredient can remove breakout-causing built up dead skin cells and excess amounts of oil on the skin’s surface.

5. Tea Tree Oil

There are a number of products on the market with tea tree oil.  While this ingredient is not approved by FDA for acne claims, it has long been used in naturally based skin care products for caring for acne-prone skin.

Whatever acne-fighting ingredient you chose, be sure to start with lower concentrations. Starting low and building up the strength over time will help you minimize the drying side effects associated with many of the acne fighters above.
