Purpose: Acne has potential to cause psychological distress and significantly diminish one's quality of life. Although washing and over-the-counter cleansers are commonly used in the treatment of acne vulgaris, clinical evidence supporting their effectiveness is still limited. The main focus of this research is to explore anti-acne effectiveness and mildness of a cleanser containing salicylic acid, gluconolactone, and niacinamide. Methods: We recruited two groups of participants. One group consisted of 43 individuals with oily acne-prone skin, and we measured their inflammatory lesions, non-inflammatory lesions, and sebum content after 4 weeks of product usage. The other group included 39 individuals with sensitive skin, and we assessed objective irritation parameters and subjective irritation parameters after 2 weeks’ product usage. Results: After 4 weeks of using cleanser containing retinol, niacinamide and ceramides on oily acne-prone skin, significant reductions were observed in both inflammatory acne lesions count and non-inflammatory acne lesions count, while there was also a significant decrease in skin sebum content. After two weeks of use on sensitive skin, significant improvements were observed in both subjective and objective irritation parameters. Conclusion: In summary, a cleanser containing salicylic acid, gluconolactone and niacinamide can effectively improve acne symptoms while being gentle enough for use on sensitive skin.
