The key to women buying skin care products is to rely on themselves. Too many experiences tell Shang Sister that he doesn't know a little bit of knowledge, and he relies on the shopping guide. It is really possible to buy it back.


So this time, Shangjie has arranged some simple and easy-to-understand skin care ingredients for everyone, first collect it, and then you can look at it again next time you buy something!


The main points of view of skin care ingredients are the location. The higher the position, the greater the content inside the product. For example, most skin care products use water as the base, the water content is the largest, and the location is also the first.


However, the concentration of the component is below the 2/1 dividing line. First, the sorting can be disordered. Secondly, regardless of the ingredients that are expensive, it is a chicken rib that can be ignored, and the effect on the skin is minimal.


There are too many cosmetic ingredients, and some people will find out the ingredients that are harmful to the skin. But is it really "harmful"?


First, these ingredients (appropriate amount) are safe
Preservative
Preservatives are basically added in cosmetics. In order to maintain the use and deterioration of skin care products, it can be said that it is essential. The main function of preservatives is to prevent fungi and bacteria.


However, some people deliberately exaggerate the precautions: the addition of preservatives may cause contact dermatitis and eczema, damage to the stratum corneum, accelerate pigmentation, accelerate cell aging, and cause skin sensitivity.


Be aware that skin care products that do not contain preservatives have a great chance of passing through the stratum corneum, causing inflammation of the skin. In addition, the products of bacterial and fungal reproduction and metabolism will become the source of allergies, causing skin diseases of contact dermatitis and eczema.


By adding preservatives to the product, bacteria and fungi can be effectively contained to protect skin care products and our skin.


Of course, preservatives are also harmful! But it brings us the benefits. And the preservatives added in the big brand skin care products have been repeatedly tested and tested by the formulator. The content and concentration have been strictly tested and controlled, and it will not cause harm to our skin.


2. Silicone oil


Silicone oil has a good lubricating effect on the skin, and the cosmetics made therefrom can form a thin layer of hydrophobic film on the skin surface.


However, silicone oil is prone to acne, and some people are arguing that silicon-containing products are not available. I don't know if the quality of silicone oil products is no longer acne.


3. Mineral oil
Mineral oil is actually a general term for a class of substances, extracted from petroleum, including white oil (also known as light oil, liquid paraffin, etc.), petrolatum, paraffin and so on. It has several outstanding advantages, so it is widely used in skin care products. The famous Lamer Blue Mystery and Sysley Almighty Emulsion contain such ingredients. Has: stability, docility, unparalleled closure, and no sensitization.
Although mineral oil can indeed clog pores, the use of vegetable oils does not pay attention to cleaning, it has the same problem), so it is recommended to avoid oily muscles and acne muscles using mineral oil ingredients, but dry, sensitive, aging skin and babies Suitable for use. This is not simply a matter of good or bad mineral oil.
It can only be said that mineral oil is only a neutral ingredient, and there is no conclusion that it can not give it a good or bad. Only see if your skin is suitable for use.


Second, what are the ingredients that are really harmful to the skin?
Hormone
Hormone is used in cosmetics. It can be said that the effect is immediate. For products with whitening, acne blemishes and redness, if the effect is particularly obvious, be careful.
Long-term use of hormone-containing cosmetics can cause telangiectasia, atrophy, and even hairy, dermatitis and other symptoms. Will make you addicted once you do not use the skin condition will be more serious.


2. Heavy metals such as mercury, lead and arsenic
The real culprit in cosmetics causing poisoning is heavy metals such as mercury, lead and arsenic. The most important reason is the excess of heavy metals.


3. Spice
Many people like the taste of cosmetics, in fact, spices are also the culprit of skin damage, which may cause health problems such as light sensitivity and contact dermatitis.


The "chromium" and "clam" contained in the fragrance are prohibited elements. If the skin is weakly used by the patient, the skin will be irritated and burning, or the skin will be sensitive and red, and severe dermatitis will result. Chromium is a skin allergen that can cause allergic dermatitis or eczema. It has a long course and is not cured.钕 is very irritating to the eyes and mucous membranes, moderately irritating to the skin, and inhalation can also cause pulmonary embolism and liver damage.


Third, these basic common sense you have to know

In order to make your products look taller, many skin care products will make you feel that you have added deep sea water and mineral water. In fact, the essence is water, and there is almost no improvement in the skin.


2. Solvents don't care too much
The ingredients such as solvents (such as butanediol, glycerol) do not have any effect on improving the skin, but only play a role in assisting the moisturizing effect. But it will not hurt the skin.


3. Don't be too blind to believe in hyaluronic acid
For the dry skin of the sister paper, seeing the composition of hyaluronic acid is like catching a straw, in fact, the role of hyaluronic acid is very limited. It actually only works a little on the surface of the skin. If you want to really solve the problem of the skin, you still need to use the medical instrument to do deep import.


4. Alcohol is not spicy, terrible
Many sisters have just started to touch the ingredients to see that "ethanol" will definitely resist, in fact, alcohol is not so evil. Alcohol is a good solvent. Some water-insoluble ingredients can be fully dissolved by alcohol, as long as the solubility is suitable, it will not cause skin damage. It can also astringe inflammation and improve the penetration of skin care products.
