Rhododendrol is primarily used in the cosmetics industry as a skin-lightening agent. It is incorporated into various skincare products, such as creams, lotions, and serums, to reduce the appearance of dark spots, hyperpigmentation, and uneven skin tone. The compound works by inhibiting the activity of tyrosinase, an enzyme involved in melanin production, thereby promoting a brighter and more uniform complexion. However, its use has been controversial due to reports of adverse effects, including skin irritation and the development of leukoderma in some individuals. As a result, its application in cosmetic formulations has been restricted or discontinued in certain regions, and safer alternatives are often sought for skin-lightening purposes.
