The Best Acne Serums - Top 5 in 2026

Bielenda Skin Clinic Professional Niacinamide Serum is a concentrated serum for acne vulgaris, formulated for skin with imperfections, excessive oiliness, and uneven skin tone. The formula is based on 10% niacinamide in a mild form with a very low nicotinic acid content, ensuring excellent tolerance even for sensitive skin prone to acne vulgaris. Niacinamide regulates sebum production in multiple ways, reduces the appearance of pores, acts as an antioxidant, and supports ceramide synthesis, thereby strengthening the skin’s lipid barrier. Alpha-arbutin, a natural derivative of hydroquinone, lightens post-inflammatory hyperpigmentation left behind by acne and evens out the skin tone of oily and combination skin. Lactobionic acid (PHA) gently exfoliates, binds water in the epidermis, and supports its renewal without the risk of irritation. Our testers didn’t like the rather modest, minimalist formula, which lacks ingredients that directly combat the bacteria responsible for acne vulgaris—the acne serum has a normalizing rather than a therapeutic effect. Some testers also noted that results are visible only after at least 4 weeks of regular use.

SkinTra Comedo-Killer is an innovative acne serum that stands out for its use of salicylic acid encapsulation technology. The encapsulated 2% BHA (salicylic acid) is released gradually and works for a longer period of time than in traditional formulations — it penetrates deep into the pores, dissolves accumulated sebum, removes dead skin cells, and cleanses the sebaceous gland openings. Azeloglycine—a compound combining azelaic acid with glycine - has antibacterial properties, soothes inflammation, regulates sebaceous gland function, and simultaneously moisturizes the skin, making it a gentler alternative to pure azelaic acid. Gluconolactone (PHA) at a 5% concentration gently exfoliates the skin without causing irritation and supports cell renewal, while shikimic acid (2%) has antibacterial properties, lightens acne-related hyperpigmentation, and cleanses pores. Testers noted the very runny consistency, which negatively affects the comfort of application and also reduces the product’s yield. Our testers did not like the relatively small volume compared to the product’s price. They also noted that the acne serum is hard to find.

Novaclear Acne Pore-Cleansing Serum is a multi-ingredient serum for treating acne vulgaris that combines four proven active ingredients. Azelaic acid has antibacterial properties, reduces the growth of bacteria responsible for inflammatory lesions, and effectively lightens post-inflammatory hyperpigmentation. Salicylic acid (BHA) penetrates deep into the pores, dissolves accumulated sebum, exfoliates dead skin cells, and unclogs gland openings. Mandelic acid (AHA) gently improves skin texture, moisturizes the skin, and supports its lipid balance. Niacinamide regulates sebum production, reduces the appearance of pores, and soothes irritation associated with acne vulgaris. Our testers noted that the product’s ingredients list includes a fragrance blend along with potentially allergenic ingredients, which may increase the risk of irritation for sensitive skin. The testers also noted that the serum’s effects on acne become visible only after prolonged, consistent use. Our testers also complained about the spray format—there is a high risk of the product getting into the eyes.

Anyong Anti-Blemish Azelaic Serum is a gentle acne serum inspired by Asian skincare rituals. Azelaic acid—the key active ingredient—regulates sebum production, supports the skin’s lipid balance, and helps reduce the appearance of blemishes characteristic of acne vulgaris. Asian pennywort extract, along with centelloids (madecassic acid, asiaticoside, and asiatic acid), has regenerative and soothing properties, accelerating the regeneration of the epidermis after inflammation. Willow bark extract gently cleanses the pores and refreshes the skin’s texture. A complex of pre- and postbiotics (inulin and Bacillus/Artemisia vulgaris ferment) supports the skin’s microbiome, strengthening its natural protective barrier. Our testers didn’t like that the product has no customer reviews, which makes it impossible to verify its effectiveness. The testers also noted the lack of information regarding the concentration of azelaic acid in the formula. Our testers were also dissatisfied with the product’s limited availability. They also cited the brand’s short history and the lack of clinical studies confirming its effectiveness and long-term impact on the skin’s appearance as drawbacks.
