EGF Beauty Factor

EGF consists of 53 amino acids and includes 3 polypeptides with disulfide bonds. The EGF precursor has a molecular weight of 130 kd, which is 300 times smaller than that of bacteria, and the human EGF gene is located on the long arm of chromosome 4. EGF can promote the proliferation and differentiation of cells, thereby replacing senescent cells and dead cells with new cells.

As the saying goes, "food depends on the ingredients, skin care depends on the ingredients", and understanding the inside and outside of things is more conducive to enjoying the benefits brought by things. Most of the friends who have a certain understanding of skin care have a habit - looking at the ingredient list of the product, products containing alcohol, preservatives, and fragrances will be deducted, while products containing strong skin care ingredients are often people's first choice. In recent years, the words "oligopeptide" frequently appear in the promotional pages of various brands of skin care products, and when you open the social platform, you will also be planted by major bloggers to plant skin care products containing "oligopeptides".

Using ingredients as a selling point is a common marketing method for skincare brands, some products are selling point hyaluronic acid, and some products are selling point is oligopeptides. Affected by product promotion, I saw the word "oligopeptide" and thought of the promotional copy such as "repairing skin" and "soothing acne" in the advertising picture.

So why is EGF still on fire in the skincare world? Is it worth buying?

The increasing popularity of EGF skin care is often inseparable from the promotion of businesses, but at present, the state is increasingly controlling the promotion of skin care products, and the State Drug Administration updated a FAQ on ** in 2019, and the "FAQ on the Supervision and Administration of Cosmetics (1)" clearly states that "unlike oligopeptide-1, human oligopeptide-1 (egf) shall not be used as a cosmetic raw material." Anything that is added to the formula or that the product claims to contain human oligopeptide-1 or EGF is an illegal product. ”

EGF is the English abbreviation of epidermal growth factor, also known as human oligopeptide-1, this substance is mainly used in medicine, and has a promoting effect on cell regeneration and wound healing. However, this substance in our country isIt is forbidden to appear in the formulation of cosmetics and skin care productsTarget.

First of all,EGF is a bit of a chicken rib when used for daily skincare。The molecular weight of EGF is relatively large, and it is difficult to be absorbed under normal barrier conditions, which means that its effect can only be fully reflected when the skin is damaged through the wound on the surface of the skin.

Secondly,The effects of EGF come with risks。If the barrier is damaged and incomplete, the "efficacy" of EGF after osmotic absorption is difficult to control, which may lead to other safety problems.

I believe that everyone has a certain understanding of EGF epidermal growth factor, I remind you that in the world of various skin care, consumers should have a rational and dialectical vision to look at the effect of the products advertised by the merchants, and regular skin care products will generally be inspected and filed with the State Food and Drug Administration.
