Adapalene sodium salt is primarily used in dermatological treatments, specifically for managing acne. It is a topical retinoid that helps to normalize skin cell turnover and reduce inflammation, making it effective in treating both comedonal and inflammatory acne. By preventing the clogging of hair follicles, it minimizes the formation of blackheads and whiteheads. Additionally, it is often prescribed for long-term maintenance therapy to prevent acne recurrence. Its anti-inflammatory properties also make it suitable for reducing redness and swelling associated with acne lesions. It is commonly found in gel or cream formulations, making it easy to apply directly to affected areas.
