Teach you 7 kinds of fire, which are proved to be effective skin care ingredients by many scientific studies ~

Centella asiatica, a "living fossil", can catch fire in the field of skin care because many related papers published by colleges or scientific research institutions have proved that Centella asiatica has the effects of calming skin, resisting bacteria, relieving pain and promoting wound healing.

Not only can it provide sufficient nutrients for the skin in multiple dimensions, but it was once called "the miracle of nature" by the beauty industry.

"Treasure" extract: contains asiaticoside, madecassoside, asiatic acid and madecassoside.

Sedation repair:

One is to inhibit the activity of sedative factors such as IL-6, TNF-α and PGE2-2;

Second, increase the skin's resistance, help the skin reduce the discomfort caused by redness, strengthen the "muscle basement membrane" structure between epidermis and dermis, and improve the health of the skin.

In particular, adding Centella asiatica into facial cleanser can play a very good role in cleaning, controlling oil, stabilizing and repairing skin.

In addition, Centella asiatica can be deeply repaired until it can improve and repair the function of the skin's own barrier and restore the skin to its best state.

Come on, come on. This piece knocks on the blackboard, which is going to popularize science!

The main component of Glycyrrhiza glabra extract is glabra glycyrrhizin, which can effectively inhibit the activities of various enzymes (such as tyrosinase) in the process of melanin production, and is an efficient and green whitening and freckle removing agent.

Glabridin can form hydrogen bonds with the active center of tyrosinase, and firmly adhere to the entrance of tyrosinase, so that the raw materials for synthesizing melanin can't get in and the semi-finished products of melanin can't get out, thus reducing the production of melanin.

Moreover, in human clinical experiments, the improvement effect is very obvious after 4 weeks and 8 weeks.

In fact, glabridin is a whitening cosmetic additive introduced by Maruyama Company in 1989. After years of use, it has obvious effect and good safety, and is the main functional component of high-grade whitening cosmetics in the world at present.

In addition, Glycyrrhiza glabra extract also has the functions of preventing hyperkeratosis and resisting bacteria.

Do you have the same doubts as me, is retinol really as powerful as it is boasted on the Internet?

Also known as vitamin A alcohol, it has always been a very popular anti-aging ingredient, and it is also recognized by the medical community as the most active anti-aging ingredient.

In 2007, the researchers asked dozens of people with an average age of 87 to use 0.4% retinol. After a period of time, the subject's skin condition has been greatly improved.

Moreover, the contents of glycosaminoglycan and collagen which affect skin elasticity have increased in individual subjects, so the anti-aging evaluation containing retinol for 4 ~ 8 weeks can obviously reduce fine lines, promote skin metabolism, whiten skin and other anti-aging effects, and restore skin elasticity.

The most important thing is that it can reduce damaged or aged skin cells, block the destruction of collagen by ultraviolet rays, effectively resist photoaging, effectively inhibit sebum secretion and remove acne, and is quite friendly to acne muscles.

Jojoba oil is really a popular blackhead remover. Is it really as mysterious as it says?

Its principle is that oil is soluble in oil: Jojoba oil has strong permeability, which can promote the loosening and dissolution of hardened blackheads, and gentle massage can help blackheads break.

Moreover, a large number of safety and toxicological tests show that Jojoba oil is very safe as cosmetic oil and will not produce acne and antigen.

Focus! ! !

Before using Jojoba oil, it is best to use a towel to open pores, and the effect will be better, and it needs to be used consistently, 2-3 times a week, and obvious results will be seen.

No one will question the ability of salicylic acid to remove acne, then you are really ignorant.

Then why is it called "acne champion" by the industry? It's all down at 3 o'clock.

Dredge hair follicles: Salicylic acid is fat-soluble, that is, it can blend well with sebum, penetrate deep into hair follicles, loosen the corner plug arch that blocks hair follicles, and excess oil will be discharged under the dredging of salicylic acid.

Sedation: Salicylic acid is a derivative, so the sedative effect is mainly achieved by inhibiting factors.

Bacteriostasis: after the hair follicle is cleaned, the excess sebum secreted by the skin will be discharged, the food of bacteria will be reduced, oxygen will enter the interior, and anaerobic bacteria (bacteria that hate air) will disappear, so dredging+bacteriostasis will go together and acne will soon disappear.

The full name of Schizosaccharomyces is the lysate of Schizosaccharomyces fermentation products, which can effectively protect the skin around eyes from ultraviolet rays and help prevent or delay the photoaging of dermis.

Schizosaccharomyces can repair the DNA damage of skin around eyes caused by ultraviolet rays.

Schizosaccharomyces can reduce the damage of ultraviolet rays in sunlight to the skin around eyes.

Therefore, Schizosaccharomyces cerevisiae is a kind of high-quality skin care ingredient with anti-aging, promoting metabolism, helping repair, preventing injury, multifunction and nourishing skin.

The whitening effect of arbutin lies in that arbutin inhibits the production of melanin by inhibiting the activity of tyrosinase (tyrosinase is the key enzyme in melanin synthesis) in vivo, thus reducing skin pigmentation and removing spots.

20 15 Zhejiang university of technology cooperated with THE TEMPLE OF JIALAN group to study the inhibitory effect of arbutin on melanin synthesis in zebrafish embryos.

The results showed that zebrafish embryos were exposed to 2mM, 4mM, 8mM and 12mM arbutin solution for 48 hours, and the melanin deposition in their bodies decreased to varying degrees, and the higher the arbutin solution concentration.

In addition, arbutin does not produce toxic, irritating and allergic side effects, but also has bactericidal and sedative effects.

Yeah! Finally, I have finished coding my little secret of amazing beauty! Now you should know how to choose skin care products, otherwise I will write in vain.
