"Natural" cosmetics are a common misunderstanding of nonsense

"I think that applying sunscreen is foolproof, and the concept of 'pure natural' for cosmetics is fascinating. These are all misunderstandings of skin care." Yesterday afternoon, at the Science Science Center held in the Science and Technology Museum, "Scientific Sunscreen, Skin Care" science lecture, skin experts reminded The public, to raise awareness of self-protection, to guard against bad merchants maliciously "playing gimmicks."

Homemade cosmetics are easy to cause skin diseases

Ms. Liu must make up every day because of her professional habits. Over time, her face gradually developed some pimples, acne, and pustules in some places. I went to the hospital to check that it was a cosmetic acne.

It is understood that, like Miss Liu, due to the mechanical blockage of cosmetic hair follicles, or inappropriate use of foundation creams, scrubs and other products, or the use of bacteria over standard cosmetics, hormone-containing cosmetics, etc. many. Professor Wang Xuemin, deputy dean of Shanghai Dermatology and STD Hospital, pointed out that "adverse reactions to cosmetics have always been a major cause of dermatology. Especially in some beauty salons."

There is no "natural" cosmetics at all.

Recently, “natural” cosmetics that claim “green” and “no stimulation” are favored by young people. In this regard, skin experts do not agree. "As far as I know, there is no completely natural product in the world in this field." The relevant person in charge of L'Oréal Global R&D Center told reporters that some products may be called "natural" by adding some natural botanical ingredients. And the practice of collecting money is irresponsible.

Sunscreen products should not "small things"

With the advent of summer, sun protection has become the focus of attention. According to Professor Wang Xuemin, according to internationally accepted standards, the definition of the sun protection index is based on 2 mg per square millimeter, but the survey found that the actual dosage of ordinary people is 0.5 mg / mm 2 to 0.7 mg / mm 2 . "So, we emphasize that sunscreen products should not be "small things" and should be applied in multiple times." Professor Wang said that when choosing skin care sunscreen products, they should be purchased from regular channels. The public should choose different cosmetics according to their skin type, season and other factors.
