First of all, it should be clarified that cosmetics here do not mean all cosmetics, but some informal or hormone-adulterated cosmetics, which can be likened to skin “opiates”. Glucocorticoids were originally three milestone drugs in dermatology, saving a number of life-threatening diseases such as lupus erythematosus and dermatomyositis, and also effectively controlling eczema and dermatitis attacks. However, when the hormones reached the hands of raw material manufacturers, they became a very popular name: “whitening agents”, and then they entered the product lines of cosmetic manufacturing plants and finally flowed to consumers. In the last ten years or so, with the improvement of living standards, the demand for beauty has been raised to a rather important position in daily life, and with the rapid development of the beauty industry and the fierce competition in the sale of beauty products, various products claiming to be “pure Chinese medicine formulas”, “skin problem-buster”, “one rubbing effect”, and “one rubbing effect” have become very popular. “A rub to see the effect”, “N days to let you white” “child magic” and so on skin care products, masks, and so on numerous, consumers in the selection process can not help but be dazzled, then try it. Many people have the mentality to try, but in the process of trying but helplessly found that this kind of “skin care products” once used on the skin condition is good, stop using on the bad. Stop using the products with hormones and replace them with safe and reliable products, there will be redness, fever, itching and other symptoms, this is called broken hormone allergy, consumers think it is because the newly bought products are not good, and then switch back to the original products with hormones, the symptoms will be immediately reduced; so repeatedly, have been in the “hormone” road deeper and deeper. The long-term use of the product leads to skin thinning, sensitivity, redness and even hairiness, and dependence on their so-called “special effect skin rejuvenation and whitening cosmetics” after long-term application, leading to hormone-dependent dermatitis.
