The science
The foundation of this body wash rests on 2% salicylic acid, a beta-hydroxy acid with decades of clinical evidence supporting its efficacy in acne treatment. Salicylic acid is lipophilic, meaning it dissolves in oil — a critical property for penetrating the sebum-filled pores that drive truncal acne. A 2024 multicenter randomized controlled trial published in the Journal of Cosmetic Dermatology (Ye et al., PMID 38590107) demonstrated that 2% salicylic acid performed comparably to adapalene 0.1% in treating mild to moderate acne vulgaris, establishing it as a viable first-line OTC option.
The inclusion of glycolic acid alongside salicylic acid creates a dual-mechanism approach. While salicylic acid works within the pore lumen, glycolic acid — the smallest alpha-hydroxy acid — operates at the skin surface to disrupt corneocyte cohesion and accelerate desquamation. A 2014 study in the Journal of Drugs in Dermatology (PMID 24918557) tested a combined 1% salicylic acid and 10% buffered glycolic acid system and found rapid improvement in mild acne, supporting the rationale for pairing these two acids.
The rinse-off delivery format is often questioned for efficacy, but evidence supports that medicated cleansers do deliver clinical benefits. A 2018 systematic review in the Journal of Dermatological Treatment (PMID 29460655) examined the clinical evidence for acne washes and found that salicylic acid cleansers, despite limited contact time, produced statistically significant improvements in acne lesion counts. More recently, a 2025 study in the Journal of Drugs in Dermatology (PMID 40465501) demonstrated that a 2% salicylic acid cleanser treated acne effectively without compromising the skin barrier.
For users with keratosis pilaris, the AHA/BHA combination is particularly relevant. A 2025 review in Cureus (Dampa, PMID 41631232) specifically evaluated topical keratolytics including alpha and beta hydroxy acids for KP and confirmed their effectiveness in reducing the characteristic keratotic papules.
