Best salicylic acid - Top 5 in 2026

La Roche Posay Effaclar serum combines a complex of exfoliating acids with soothing active ingredients to create an advanced formula for fighting skin imperfections. Salicylic acid and other keratolytic acids systematically remove dead skin and unclog pores, while working to reduce acne blemishes. Niacinamide, combined with thermal water, forms a soothing duo that soothes irritation and reduces redness typical of acid use. The product's lightweight texture makes for comfortable application, but those with very sensitive skin should start with 1-2 applications per week to test the skin's reaction. Testers noted that the serum may initially increase sun sensitivity, so high sun protection is necessary. Disadvantages of the product include the need for a gradual introduction to skin care and possible dryness of the skin with too frequent use. In addition, due to its acid content, it is not recommended for summer use without adequate photoprotection. Our testers also noted the high price of the product.

Garnier Vitamin C Serum is a formula that combines three key active ingredients to fight hyperpigmentation. A stable form of vitamin C (3-O ethyl ascorbic acid) at a concentration of 3.5% not only lightens existing discolorations, but also has an anti-aging effect. Niacinamide promotes skin regeneration and strengthens the skin barrier, while salicylic acid gently exfoliates dead skin, accelerating cell renewal. Our testers observed that the addition of lemon extract, rich in antioxidants, supports whitening and brightening effects. The serum's lightweight formula absorbs quickly, allowing for both morning and evening use. Our testers noted several drawbacks to the product. The relatively low concentration of vitamin C can prolong the time to see results in those with intense hyperpigmentation. Some testers also reported a slight pinching upon application and a not-so-pleasant product smell. Additionally, the lemon extract may cause irritation in those with sensitive skin.

Vichy Normaderm Serum Against Imperfections with BHA Acid is an advanced formula designed for problematic skin. It contains a 5% complex of salicylic (BHA) and glycolic (AHA) acids that effectively exfoliate dead skin, reduce blemishes and discoloration, and unblock pores. The addition of probiotic fractions with volcanic water soothes the skin, promoting skin regeneration. Testers confirmed that the serum with salicylic acid accelerates skin renewal processes, improving skin texture and reducing excess sebum. Although use of the serum quickly brings results, testers with sensitive skin noted slight irritation caused by salicylic acid. Some testers also observed dryness of the skin with too frequent use - probably due to the presence of denatured alcohol in the formulation. The price of the cosmetic is quite high.

Nacomi Next lvl Salicylic Acid combines 2% salicylic acid with vitamin B3 and activated charcoal to create a comprehensive formula for problematic skin. Salicylic acid effectively penetrates pores and dissolves sebum build-up, while exfoliating dead skin. Vitamin B3 works on several levels - it regulates sebum production, supports the hydrolipid barrier and stimulates collagen production, resulting in improved skin firmness. Activated charcoal rounds out the formula, acting as a magnet for impurities and excess sebum, further supporting the mattifying action of the serum. Our testers noted the product's thick consistency, which makes it difficult to apply evenly. Testers observed that the black color of the serum can leave marks on light-colored bedding. Some users also reported dry skin with daily use and a long absorption time. A major downside is also the inability to combine with popular anti-aging ingredients like retinol or bacuchiol, as the product can react with other cosmetics.
