"The big brand I bought, why are I still allergic?"
"Friends use it very well, how do I use it with sting?"
"I have watched the strategy on the Internet for a long time and selected this one, how can it not work?"
"What exactly can pregnant women use?" So irritable! ”
Wait a minute......
Does it work? You only know it if you have tried it yourself, but conditions such as allergies and irritations can be avoided as long as you read the ingredient list.
What you need to know about the ingredient list!
1. The higher the ranking, the greater the proportion of this ingredient in the cosmetics
In the fully identified ingredient list, the ingredient names are arranged according to the amount added from most to least. For example, water is the most commonly used medium in cosmetics, so it is generally at the top of the ingredient change. Other commonly used solvents are ethanol (alcohol), glycerin, butylene glycol, etc., also ranked in the front position, their role in addition to basic moisturizing, more role is to help dissolve the active ingredients in cosmetics.
Many people will resist when they see "ethanol" in the ingredient list of skin care products, but in fact, it is not necessary. Because alcohol is also a commonly used solvent, some water-insoluble ingredients must be fully dissolved with the help of alcohol, as long as the content is moderate, it will not cause harm to the skin, and it also has the effect of astringent inflammation and improving penetration. However, sensitive skin and those who are allergic to alcohol should use with caution.
2. Two important "references" - preservatives and keratin components
Preservatives (phenoxyethanol, potassium sorbate, methylparaben, polyols, etc.) and colloidal ingredients (carbomer, xanthan gum, etc.) in the formula will never exceed 1%, that is, if ranked after these ingredients, then its effect can be basically negligible, and the improvement effect on the skin is minimal.
3. Thick texture does not mean nutrient rich
Mask is also thick and can not be equated with high nutrition painting, many times is due to the addition of gum to achieve visual illusions, such as carbomer, xanthan gum, hydroxyethyl cellulose, acrylic (ester), etc., these ingredients can create a more rich texture appearance and refreshing sense of use, but in fact the skin is useless and harmless.
4. Sensitive skin needs attention - flavors and preservatives in cosmetics
Flavors and preservatives are the most common allergens that cause contact allergies in Cosmetics in China. If you are prone to allergies, then the following ingredients you need to pay attention to.
More than 150 flavors can cause contact allergies, the most common of which are linalool, limonene hydroxide, hydroxyisohexyl-3-cyclohexenoal, lichen, iso eugenol, cinnamyl alcohol and cinnamaldehyde, usually in some deodorants, perfumes and post-shaving products. The composition of moisture, protein, amino acids, unsaturated fatty acids and other components in cosmetics provides a material basis for microbial reproduction, in order to prevent cosmetics from being contaminated by microorganisms in the process of production, storage and use, different types of preservatives are often added. Note in preservatives are methylisothiazolinone (MCI) and methylchloroisothiazolinone (MI), which are the most common allergens. The frequency of use of MI in cosmetics is still relatively high, about 6.35%, especially cleaning products (the frequency of use is 10.8%), and the frequency of use of mask products is also very high.
Pay attention to the choice of cosmetics of regular manufacturers, in the choice of cosmetics, you can try to choose fragrance-free or preservative-free products achieved through special packaging materials and technologies.
