Pigmented cosmetic dermatitis

Women's facial melanosis is also known as Pigmented Cosmetic Dermatitis. This disease occurs in Japan and was named as pigmented cosmetic dermatitis by Japanese scholar Nakayama on this basis. In recent years, the use of cosmetics by Chinese women has increased year by year, and the incidence of cosmetic dermatitis has also increased. The clinical features are diffuse or plaque hazel, gray-brown to purple-brown pigmentation in the palate, temporal, cheek, and forehead of women, and the severe spread to the entire face with itching.
