The difference between cosmetics and advertising

The advertising beauty is beautiful and the skin is as smooth as water. But is it really the credit of cosmetics ? What is the difference between reality and reality?

Three days to spot, one week white and credible? Whitening products generally contain different concentrations of lead, mercury, kojic acid, arbutin, vitamin C, fruit acid, hydroquinone, phenolic substances. Among them, lead and mercury are substances that are prohibited by the state from being used for whitening. They can be absorbed through the skin, causing poisoning to the body. Although whitening products can inhibit the activity of tyrosinase to a certain extent, prevent melanin production, and have the effect of diminishing skin tone, but its effect is not once and for all, once stopped, tyrosinase will be active again, whitening effect will disappear slowly.

Can wrinkle cream really smooth out the signs of age? Skin aging and wrinkles are something that everyone can't avoid. The main ingredients in the wrinkle cream are nothing more than collagen, mucopolysaccharide, botulinum toxin, antioxidants, moisturizers , keratolytics and vitamins. The effect of these ingredients is to slow down the process of wrinkling, to cover wrinkles, or to temporarily relieve the effect, and not to receive the effect of truly eliminating wrinkles.

Can the skin absorb the nutrients in cosmetics? The skin is the outermost protective barrier of the human body. It has a multi-layered structure. The uppermost part is the stratum corneum composed of dead keratinocytes, which can effectively prevent bacteria and harmful chemicals. Intrusion.

There is also a lipid film on the surface of the stratum corneum, which makes the skin smooth, shiny and prevents evaporation of water in the body. The presence of the stratum corneum and lipid film renders the skin impervious to water. The natural protective mechanism of human skin only allows a small amount of water and fat-soluble substances to pass through, and many water-soluble substances in cosmetics, such as vitamin C, macromolecular proteins, etc., are not able to penetrate the skin through the stratum corneum or hair follicle sebaceous glands. Absorbed.

The nutrients necessary for skin tissue metabolism, such as sugar, fat, protein, electrolytes, vitamins and water, can only come from the blood supply of small blood vessels in the dermis. Any nutrients that enter the body through the skin cannot be directly used by the cells. Even if the various nutrients in cosmetics and skin care products can partially penetrate into the skin, at most, it is a superficial effect and a covering effect. What really works is the lipid component, which adds a lipid film to the skin and can moisturize. Anti-dry.
