Marmesin is the component of thanaka responsible for sun protection. In 2004, Joo and colleagues extracted marmesin from thanaka bark and determined its molecular structure. They found that marmesin contains UV-absorbing chromophores, with maximum absorption 335 nm, and concluded that marmesin could be a commercially useful UV-A filtering product.3
Scientific understanding of the mechanism of action of thanaka has increased popularity of the product. It is no longer a secret of the native people of Myanmar (Figure 2). Cosmetic companies in Myanmar and Thailand are increasingly adding thanaka as a natural ingredient to their products and marketing these products internationally.
