TLDR Adapalene 0.1% effectively reduces acne by decreasing comedones and altering skin properties.
The study assessed the efficacy of 0.1% adapalene in a non-inflammatory acne model using Kyoto rhino (krh/krh) rats, which develop comedones with hair loss. Over 12 weeks, krh/krh rats treated with adapalene showed a significant reduction in open comedone areas, increased epidermal thickness, and decreased lipid production compared to the control group. Additionally, cytokine production, including IL-10 and IL-12a, tended to increase with adapalene treatment. The results suggested that krh/krh rats are a suitable model for non-inflammatory acne and that adapalene effectively reduces open comedones by modifying lipid metabolism and cytokine production.
