Hyaluronic acid is not a hormone, but an anti-aging ingredient developed and patented by L 'Oré al Group. What is the scientific name of Bose mentioned in Baidu Encyclopedia? Hydroxypropyl tetrahydropyranol? So we can't find it on the product packaging? Boson? This name, only its scientific name. This ingredient can promote the formation of collagen in skin, make skin fuller and more elastic, thus forming prevent wrinkles to a certain extent, and now it has become one of the three anti-aging giants in skin care products.
However, because it is a patented ingredient of L 'Oré al Group, it is only used in some high-end skin care products of L 'Oré al, and the price will be higher, such as Helena Rubinstein's black bandage and white bandage cream, and Lancome pure cream. These creams are very popular in the market, and the favorable rate is relatively high. If hormones are added to skin care products, the most obvious symptom is that after using skin care products for a few days, the skin will suddenly become smoother and more delicate, and the effect is very obvious. However, once the product is stopped, allergic symptoms such as pimples, redness, peeling and itching will appear on the face.
