Which ingredients are better in skin care products?

1. Ceramide

itself Ceramide exists in human skin and is the main component of the intercellular lipoid body in the stratum corneum on the outside of the body’s skin. It can prevent moisture from emitting, avoid external irritation to the skin, play a certain protective function, and also achieve moisturizing and moisturizing effects. When the content of ceramide in the skin is reduced, it can destroy the skin barrier, causing dry, itchy, rough or sensitive skin, and even cause a series of skin diseases such as atopic dermatitis or psoriasis. Now many skin care products have added ceramide, which can be used externally to repair the skin barrier. Because ceramides exist in the natural structure of the skin, they generally do not appear sensitive, and are especially suitable for sensitive, dry and aging skin.

2. Glycerin

In fact, glycerin is not the best moisturizing ingredient, but the cost performance is the highest, and the price is very cheap, only a few dollars. Usually in the ingredient list of skin care products, glycerin exists as glycerol, which is a good moisturizer and solvent. Glycerin has good moisture absorption, which can absorb moisture from the air and leave a protective film on the surface of the skin. But glycerin must be diluted. Glycerin alone cannot achieve a certain moisturizing effect, and it needs to be used with other products.

3. Hyaluronic acid

Hyaluronic acid is also known as hyaluronic acid, which is often used in micro-plastic surgery. Hyaluronic acid is a substance that already exists in the skin. Hyaluronic acid has a powerful moisturizing effect, because hyaluronic acid can carry more than 500 times its own moisture and has powerful moisturizing ingredients. But when choosing hyaluronic acid skin care products, it is necessary to distinguish the molecular size, so as not to affect the effect of hyaluronic acid. Small molecules of hyaluronic acid can penetrate deep into the dermis and improve dry and aging skin problems; medium molecules can moisturize the stratum corneum, which is conducive to skin moisturization; large molecules can form a barrier on the surface of the skin to avoid moisture loss, but the touch is relatively sticky. It’s just that the effect of single-ingredient hyaluronic acid skin care products is not very good. You need to choose a moisturizing skin care product that combines the three molecules.
