Proper use of the standard period
A1 Cosmetic pigment abnormalities are mostly caused by direct dyeing or stimulation of skin pigment hyperplasia by cosmetics, and can also be secondary to cosmetic dermatitis or cosmetic photosensitive dermatitis. They should be diagnosed based on medical history and symptoms and necessary patch tests (see Appendix A of GB17149.2-1997) and light patch tests (see GB17149.6-1997).
A2 Cosmetics containing impure petroleum distillation products, certain dyes and photosensitive fragrances can all cause skin pigment abnormalities. A3 There are many factors that cause skin pigmentation changes. Attention should be paid to distinguishing from non-cosmetic-induced yellow mattress spots, black spots on the face of women, pigmented lichen planus, melanosis, Addison's disease, vitiligo, simple pityriasis, etc. A4 The diagnosis of cosmetic skin pigmentation abnormalities mainly depends on medical history and clinical manifestations. Histopathological and endocrinological examinations can be performed when necessary. 448
