P-hydroxybenzoic acid (does para-hydroxybenzoic acid have side effects on the human body?)
As an essential product for our daily skin care, we should be familiar with it, but in fact, many people just use masks blindly, I know little or nothing about the ingredients of the mask, just staring at the efficacy in the product description. Understanding the ingredients of the mask can do more with less for our targeted skin care. So what are the ingredients of the mask? Check it out with you!
What are the ingredients of the mask?
The main ingredients of different masks are different, mainly because the masks of various materials are injected with natural moisturizing factors (essence ). The materials of masks are also various, which can be roughly divided into three types: non-woven fabrics, silk, and biological fibers. Mask is a category of skin care products. Its most basic and important purpose is to make up for the lack of makeup remover, face cleansing, and on this basis, cooperate with other essence ingredients to achieve other maintenance functions, such as moisturizing, whitening, anti-aging, balance Grease, friends and resources, and more. For normal healthy skin, apply a mask once or twice a week, even in dry northern regions. If you feel that your skin is particularly dry recently, or you feel uncomfortable after cosmetic laser treatment, you can apply it continuously for 3 to 7 days (depending on the degree of dryness). Then keep the frequency of once or twice a week.
What are the safer ingredients in the mask?
1. Preservatives. Because the water content in the mask is very large, its raw materials such as oil, amino acid, etc. are easily contaminated by microorganisms. Moreover, the production environment of masks has high requirements for anti-corrosion capabilities, so masks are inseparable from preservatives.
Many allergenic preservatives contained in facial masks refer to parabens, also known as parabens, including methyl, ethyl, propyl, butyl, etc. Most preservative ingredients. These elements can be quickly absorbed, metabolized and excreted by the human body, and are considered to be a highly safe preservative.
2. Moisturizing cream, the essence of thickening mask cream. The most abundant ingredient is water, and the second largest additive is humectants. The most common humectants are various small molecule polyols, such as glycerin, propylene glycol, butylene glycol, etc. There are also polymeric moisturizers, the most common being hyaluronic acid. Of course, other non-polyol moisturizers include amino acids, collagen, PCA-sodium, and more.
3. Whitening ingredients. Generally speaking, the whitening ingredients of the mask mainly include vitamin C, licorice extract, mulberry extract, melatonin, placenta, fruit acid, arbutin, kojic acid, etc. Fruit acids have skin rejuvenation, whitening, and exfoliation effects, but too much will corrode the skin, make it thinner, and make it very sensitive. And these ingredients can not quickly whiten the skin. Most of the fast whitening masks on the market exceed the standard of lead and mercury. Long-term use will cause severe fibrosis of the skin, and it will be sensitive to peeling and sensitive to light, and even cause great damage to your own organs and nervous system.
