Autumn and winter to double lock water to moisturize

Autumn and winter to double “lock” water to moisturize

The deepest feeling in autumn is that your skin is too dry?
Understanding the ingredients and functions of moisturizing cosmetics will definitely help you.

.hzh {display: none; }  人的皮肤有天然的保湿系统,由水、天然保湿因子(NMF)、脂类三种物质组成。The moisturizing cosmetics we are using are a simulation of this system. The main ingredients of moisturizing products are water, humectants and oils.
  Common humectants in cosmetics include: Glycerin: is the oldest humectant. Ten years ago, many people directly used glycerin and water to care for winter skin.
Safe and inexpensive, it is the most common moisturizer in cosmetics.
  Hyaluronic acid (HA): is a natural moisturizing ingredient in human skin. It retains moisture better than any natural or synthetic polymer.
Because the price is high, the amount of addition is generally not large.
  Ceramides and collagens: is the latest generation of moisturizers developed in recent years. Because they are similar to the structure of the material that forms the stratum corneum of the skin, they can penetrate into the skin quickly and combine with water in the stratum corneum to form a network, Lock in moisture.
Because its moisturizing principle is different from traditional moisturizers, some people say that it has opened up a new world of moisturizing. However, because it is too expensive, it is not used as the main component of moisturizing, and the amount of addition is extremely small.
  Urea: Rhenium is the product of the natural metabolism of the skin. It works wonderfully to soften the skin. Many hand creams contain urea.
  Chitin derivatives: is a natural humectant extracted from the shell of crustaceans. Its effect is similar to hyaluronic acid. It is a physiologically safe humectant. In addition, it is also used as a medicine for artificial skin and wound healing.
  Aloe Vera: A plant-based moisturizer.
Because aloe juice contains mucopolysaccharides (similar to hyaluronic acid), it has good lubricating and moisturizing effects, as well as sun protection and anti-inflammatory effects.
  Seaweed Extract: The seaweed is the oldest plant in the world. It has no roots, flowers and fruits.
Rich in amino acids, vitamins and mucopolysaccharides, it has moisturizing, lubricating and anti-wrinkle effects on the skin.
  Common oils in cosmetics are: Vaseline and white oil: is a mineral oil extracted from petroleum, which has good water retention and safety, but has poor breathability, which makes the skin feel “stuck”.
The price is low and it is the oil used in the middle and low-grade moisturizers.
  Jojoba oil: Coriander is taken from the fruit of Simon’s Wood.
The main ingredients are unsaturated higher alcohols and fatty acids, which have good stability and are easy to fuse with the skin.
Japanese cosmetics have been obsessed with jojoba oil, and they have been added to high-end makeup brands.
  Wheat germ oil: It is derived from wheat germ. The content of VE (that is, tocopherol) is very high. It is a high-quality emollient.
European cosmetics manufacturers like to use it and add it to high-end makeup brands.
  Squalane (deep-sea shark liver oil): Squalane is abundant in shark livers produced in the deep sea. It is rare and has extremely high chemical stability. It uses animal oils with excellent sensation and can inhibit the growth of mold.
  Silicone oil: It is a new generation of oil developed in the 1970s and 1980s. Its stability is comparable to that of petroleum jelly, and it has good antistatic and breathability, allowing the skin to breathe freely. It is an oil widely used in all grades of moisturizers.
  Lanolin: Lanolin has a very good affinity with the skin. It can form a lightly absorbed smooth film on the skin surface and is a good softener.
However, some lanolin has a slight odor. If the amount of lanolin is large, add a lot of flavors to mask its odor.
  Most of the moisturizing ability is cream products with high oil content, but remember that the higher the moisturizing ability, the better, it depends on your skin type.
In this sense, moisturizers are not good or bad, as long as they feel comfortable, they are the best for you, regardless of whether the price is expensive or low.
