How to judge the quality of cosmetics?
Cleanser:
1. There is a faint fragrance, and it should be melted in water when squeezed on the hand, and there is no greasy feeling.
2. Burn with fire, put the facial cleanser into a spoon, and burn with fire. If you splash oil, it is not a good facial cleanser. If you burn more and more like milk, it means it is a good facial cleanser.
3. Just try the PH test strip, and you will know by squeezing it directly onto the test strip.
Lotion:
1. Shake vigorously and look at the bubbles after shaking.
A. Few bubbles indicate less nutrition.
B. There are many but large bubbles, indicating that it contains salicylic acid. Salicylic acid has a better cleansing effect, but irritates Dayee allergy.
C. The bubbles are very thin and disappear quickly, indicating that they contain alcohol. Do not use it for a long time, it is easy to damage the protective film of the skin.
D. Bubbles are delicate and rich, with a thick layer that lasts for a long time, which is good water.
2. Good quality non-alcoholic taste. Bad use has a cool feeling and smells of alcohol.
3. Generally, makeup water has colors. If the storage location is improper, it is often exposed to sunlight or stored for too long, the color will fade;
4. The bottle of toner is non-transparent, so never buy it. Because it cannot be identified.
Lotion:
1. Smell the taste. Good products are pure and do not need strong fragrances to suppress product odors.
2. If it is a lotion, take a cup of water and pour the lotion into the water a little bit. If it floats on the water, it proves that it contains oleolite ester (which is not recommended for cosmetics now). After shaking it, the water turns milky white, which proves that it contains emulsifier. Such cosmetics are not good. If you pour it into the water and the lotion sinks to the bottom, it proves that it does not contain oleolite, which can be used. Oleolite ester will hurt the skin and cause dry skin and lack of water, because it is the main reason for clogging pores. Over time, the pores will get bigger and bigger. This is what experts (a very big head in the cosmetics industry, forgot) said.
Cream:
1. Put a little in an ordinary spoon, burn it over fire until it is completely burned out. If there is black residue, it is a variety of additives. The more it proves, the more additives, then put a cotton core in the spoon and light the cotton core. You will see that the water will emit black smoke. Such a product is also not good.
2. Moisturizing products, many are made of mineral oil, you apply them to the paper, and wipe off the excess after a while. If it is moisturized, the paper will wrinkle. If it is made of mineral oil, you will find that it is transparent!
3. You can also squeeze the product into an iron spoon, and then there is a fire below to heat it up. If it contains mineral oil, the oil will come out!
4. When canning the cream, if it is a finished product with good filling technology and fine texture, its surface will show a uniform and smooth shape, and there will be no large and small holes.
Serum:
For liquid serum, you must pay attention to the color and shape of the serum when purchasing. If you find cloudy, sedimentation or discoloration, such serum can no longer be used. Consumers with oily, acne and other susceptible skin must be careful when purchasing and using serum. Even if you buy it, you must choose serum with anti-inflammatory and bactericidal effects.
Foundation:
1. Take an appropriate amount and put it in the water, and then observe its reaction. Generally, three situations will occur: stick to the edge of the cup, float on the water surface, and sink to the bottom of the cup.
These three situations explain the XXX it contains. Good products do not stick to the edge of the cup, do not float, and do not sink the bottom of the cup.
A. Sticking to the edge of the cup is animal oil.
B. Floating on the water is mineral oil.
Makeup:
Find a silver jewelry and put makeup or makeup on it. If the silver jewelry turns black, it means that there is lead and mercury in the makeup.
Makeup remover:
When choosing, wipe some oily foundation or waterproof lipstick first. Put mascara and other products on the back of your hand, then pour some makeup remover and wipe it evenly to see if it is easy to blend with the makeup and can be wiped off with a facial tissue. Makeup remover that has been in the store for too long will appear like bean flower or salted soy milk, with lumps.
