What's the difference between skin care products sold in pharmacies?

First of all, when choosing cosmetics, you must know your skin. If you have normal skin, just go to the right place according to the mixture of dry oil. If you are so sensitive that you can only use baby skin care products to avoid allergies, or your skin has symptoms such as dermatitis or acne, then give up all the attractive advertisements in colorful magazines and honestly go to the drugstore to buy skin care products specially sold by pharmacies. It should be noted that not all skin care products sold by pharmacies are aimed at these problematic skin. For example, Vicky, who used a zipper to change her skin to scare children in TV commercials, is actually just a common skin care product sold in pharmacies. At present, Vichy, la roche-posay and Yang Ya are all sold in pharmacies. On the surface, they all contain natural mineral spring ingredients, but in fact they are very different. The natural mineral springs used by Vichy are rich and miscellaneous, and are mainly used to treat stomach diseases locally. La roche-posay and Vichy both belong to L 'Oré al Group, similar to Vichy. However, Yayang entered the China market late, with little publicity and single packaging, lacking the ability to impress female consumers, and its price even exceeded Vichy's. In fact, Yang Ya is produced by a French pharmaceutical factory. The most famous product of this pharmaceutical factory is an anticancer drug. Generally speaking, the quality of skin care products produced by pharmaceutical companies is far superior to that of ordinary cosmetics, because they will control the ingredients of the products more strictly, and will not add ingredients that cause skin sensitivity or stratum corneum thickening, and will not make the skin dependent. All skin care products in Yang Ya contain unique spring active ingredients. At the earliest, a French nobleman found that one of his horses had skin diseases, so he bathed himself with spring water and gradually recovered, so the effect of active spring water was recognized by everyone. All three brands now have mineral spring sprays. The most effective way to choose this spray is to spray it into your mouth and taste it. If you feel salty, it means that high mineral content will increase the burden on your skin. At present, Avon spray is the only product of this kind that Air France is allowed to take on board. In foreign countries, some cosmetic surgery, such as dermabrasion, has a large trauma area, and doctors will spray Avena spray on patients while doing the surgery. Because living spring water can calm and soothe the skin, relieve the symptoms of redness, swelling, heat and itching, help the skin to establish its own natural barrier as soon as possible, and reduce the stimulation of surgery on the skin. In addition to pharmacies, Yang Ya also sells dermatology abroad, which is the biggest difference from the other two brands. At present, many patients with dermatitis are treated with hormone ointment, which will cause drug dependence of the skin and thicken and harden the stratum corneum. Avon's product classification is very fine, and it can even be used for atopic dermatitis or other skin diseases, which can help the skin to return to normal function. Cosmetics have a lot of knowledge and a high market share. Brands with more people are not necessarily good, but some less well-known brands are easy to use. Sophie will speak slowly when she has time.
