Harm of common cosmetics:
Cosmetic dermatitis refers to an inflammatory skin disease that causes the skin of face or other makeup parts when cosmetics are used in beauty or oil painting. The clinical manifestations are erythema, edema, blisters, papules, exudation, scabbing, itching, pigmentation and so on.
Generally speaking, there are two aspects: first, the internal quality of cosmetic raw materials, preservatives, decolorants, spices, sunscreens, sweating agents, emulsifiers, hair dyes and some heavy metal substances in cosmetics directly stimulate the skin or cause allergic reactions to varying degrees; Some ingredients in some cosmetics also have photosensitivity. After use, sunlight and ultraviolet radiation cause skin photosensitivity reaction, leading to erythema or pigmentation.
On the other hand, improper use of expired and contaminated cosmetics or methods, such as long-term use of pharmaceutical cosmetics containing steroid hormones, can cause folliculitis, hirsutism, vasodilation, skin atrophy and other reactions.
Cosmetics may have direct primary irritation or allergic reaction after contacting the skin, and some photosensitive substances may have photosensitive reaction or phototoxic reaction after entering the skin, which is the basic pathology of cosmetic dermatitis.
