Analysis of the ingredients in skin care products

In the face of a variety of ingredients on whitening products, do you know how to choose the right whitening products by looking at these ingredients? Let's learn together with Xiaobian!
Whitening is the highlight of most oriental women's skin care skin and is also a theme of skin care products. The stars on the advertisements are always white, and the explanations of the shopping guides are always the head. The ingredients on the products are always varied. In fact, in those bottles and jars, no matter how many "high-tech" ingredients are contained, what can make us white is nothing more than those substances. If you know them, you will not be led by the shopping guide.
Vitamin C
Validity: ★★
Security: ★★★
Price: ★★
Also known as ascorbic acid, it has a strong anti-oxidation effect, mainly by reducing melanin to whiten the skin, dilute the pigmentation and enhance the whitening effect. It is safe and gentle and is widely used.
The whitening effect of vitamin C has a lot to do with its structure and state. Therefore, even if the two products contain the same concentration of vitamin C, the effect is not necessarily the same.
In general, L-type vitamin C, which we call L-C, has a better whitening effect.
Because the nature of vitamin C is extremely unstable, it is not hot enough, there is no sunlight, and air contact is not good, so its effectiveness is also related to the product's protection measures for vitamin C. Some whitening cycle care products are in powder form and are added immediately when used. This is a better protection for vitamin C. In general, the protection of vitamin C by large manufacturers will be in place.
Arbutin effectiveness: ★★★★★
Security: ★★★★
Price: ★★★★★
The chemical name is hydroquinone glucoside, which is extracted from a leaf and fruits such as pear, hill and pear. The principle of whitening is to reduce the formation of melanin by inhibiting the activity of tyrosinase.
Arbutin is faster than the common whitening plants to extract vitamin C. It is less irritating than medicinal hydroquinone and is a trump card ingredient for whitening.
At present, the concentration of arbutin in the skin care products must be below 7%.
However, arbutin raw materials are expensive, reaching 10,000 yuan per kilogram, and even many schools' laboratories are not available because of the high price. High-end skin care products are often used as a promotional focus. Therefore, if it is a cheap skin care product that claims to contain arbutin, you don't have to believe it.
