Why are glycerin added to skin care products?
Glycerin is indispensable in almost all moisturizing skin care products. Glycerin can be seen in the boxed ingredients of any skin care product. Why is glycerin so favored and loved by skin care products?
Next, Better Chemical tells you why glycerin is so popular in skin care products:
1. Glycerin is highly absorbent and moisturizing
The scientific name of glycerin, glycerol, is an alcohol substance that is infinitely miscible with water, such as ethanol (alcohol). Glycerol has a characteristic that it has strong water absorption (1 gram of glycerin can absorb 0.6 grams of water), so glycerin can absorb the moisture in the air to moisturize the skin, and can also lock the moisture in the skin, leaving the moisture in the keratin. layer and don't let it run off.
2. Glycerin is naturally harmless
Glycerin is a natural product, water-soluble, harmless to the skin, non-toxic, and generally recognized as safe (GRAS) for the human body.
3, the compatibility of glycerin is strong
Glycerin is compatible with many substances, mixes well, and has antioxidant properties, so it can be used as a base, emollient, humectant, lubricant, and solvent in a variety of skin care products.
4. Glycerin can enhance skin resistance
With regular and regular use, it can help the skin heal well, reduce the occurrence of associated dermatitis, and restore the normal barrier function of the skin. Glycerol absorbed into the intercellular layer also allows the sebum lipids to function better.
ps: It should be noted that:
Glycerin does not have special functions such as supplementing skin nutrition.
Glycerin in skin care products works well as a humectant to absorb moisture in the air, but when the skin is too dry, it also absorbs moisture from the dermis, dehydrating the skin.
Of course, too high concentration of glycerin will be irritating, and because the moisture absorption effect is so good, it may directly absorb water from the skin when used directly on the skin.
Therefore, it is best not to use glycerin for skin care alone, and usually buy a reliable brand of skin care products.
