Richenoic acid is used primarily in dermatological treatments due to its ability to regulate skin cell turnover and reduce inflammation. It is commonly formulated in topical creams and serums aimed at treating acne, psoriasis, and photoaged skin. The compound helps unclog pores, diminish hyperpigmentation, and improve skin texture over time. Its keratolytic properties make it effective in promoting the shedding of dead skin cells, allowing for clearer and smoother skin. Additionally, it is sometimes included in cosmetic products designed to enhance skin radiance and even tone. Due to its sensitivity to sunlight, it is often recommended for nighttime use and should be paired with sunscreen during daytime.
