1. It has a faint fragrance, and it should be water-soluble in your hand without greasy feeling.

2. Use fire, put the facial cleanser into the spoon and use fire. If you spill oil, it is not a good facial cleanser. If it burns more like milk, it means it is a good facial cleanser.

3. Just try the PH test paper. Just squeeze it on the test paper.

Toner:

1. Shake hard and watch the bubbles after shaking.

A. Less bubbles means less nutrients.

B. There are many bubbles, but they are very big, indicating that they contain salicylic acid. Salicylic acid has a good skin cleaning effect, but it is irritating and allergic.

C. The bubbles are many and 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. The bubbles are fine, rich and thick, and will last for a long time. That is good water.

2. Good quality, no alcohol smell. It doesn't work well. It has a cool feeling and smells like alcohol.

3. Generally, makeup water is colored. If stored improperly, often exposed to the sun or stored for too long, it will fade;

The bottle of toner is opaque, so don't buy it. Because it is unrecognizable.

Emulsion:

1. Smell it. A good product has pure ingredients and does not need strong spices to suppress the odor of the product.

2. If it is emulsion, take a glass of clear water and pour the emulsion into the water little by little. If it floats on the water, it proves that it contains oily resin (cosmetics are not recommended now). Shake it and the water turns milky white, which proves that it contains emulsifier. Such cosmetics are not good. If poured into water, the emulsion sinks to the bottom, which proves that it does not contain oily resin. This can be used. Oilstone ester will harm the skin, resulting in dryness and lack of water, because it is the main reason for blocking pores, and over time, pores will become larger and larger. This is what experts say.

Cream:

1. Put a little in an ordinary spoon until it is completely burnt. If there is black residue, it is all kinds of additives. The more additives are proved. Then put a cotton core in the spoon and light it. You will see that the water will emit black smoke. This product is not good either.

2. Moisturizing products, many of which are made of mineral oil, will be wiped off after being coated on paper. If you keep it moist, the paper will wrinkle. If it is made of mineral oil, you will find it transparent!

3. You can also squeeze the product onto an iron spoon and heat it with fire. If it contains mineral oil, the oil will come out!

4. When the cream is canned, if it is a finished product with good filling technology and delicate texture, its surface will be even and smooth, and there will be no holes.

Essence:

For liquid essence, you must pay attention to the color and shape of the essence when purchasing. If turbidity, precipitation or discoloration are found, such essence can no longer be used. Consumers who are prone to skin infection such as oily skin and acne must be cautious when purchasing and using the essence, even if they buy it, they should choose the essence with anti-inflammatory and bactericidal effects.

Basis:

1. Put appropriate amount into water and observe its reaction. Generally, there are three situations: sticking to the side of the cup, floating on the water surface and sinking at the bottom of the cup. These three situations illustrate the components contained in it. Good products do not stick to the rim of the cup, float or sink the bottom of the cup.

A.what sticks to the edge of the cup is animal oil.

Floating on the water is mineral oil.

C. heavy metals, lead, mercury, etc. Sink at the bottom of the cup.

Makeup:

Find a silver ornament and put cosmetics or makeup on it. When the silver ornaments turn black, it means that there are lead and mercury in cosmetics.

Makeup remover:

1. When you choose, you should first apply some oily foundation or waterproof lipstick, mascara and other products on the back of your hand, and then apply some makeup remover evenly to see if it is easy to blend with makeup products. You can wipe it off with a facial tissue. If you leave makeup remover in the store for too long, there will be lumps such as tofu pudding or salted soybean milk.

2. Moisturizing products, many of which are made of mineral oil, will be wiped off after being coated on paper. If you keep it moist, the paper will wrinkle. If it is made of mineral oil, you will find it transparent!

3. You can also squeeze the product onto an iron spoon and heat it with fire. If it contains mineral oil, the oil will come out!

4. When the cream is canned, if it is a finished product with good filling technology and delicate texture, its surface will be even and smooth, and there will be no holes.

1, smell the fragrance, the lighter the better.

Many ingredients in cosmetics are minerals or extracted from plants. Because the components in minerals are complex, the useful components extracted by our existing technology will contain a lot of impurities (other mineral components), and most of the components extracted from this mineral will not have bad smell (mutton taste and shameful taste). In order to cover up this unpleasant smell, we added a strong fragrance to this cosmetic. Low mineral cost, simple process and low technical requirements. Many manufacturers will choose this raw material. Plant raw materials are expensive, and the extraction process is of course much more complicated than that of minerals, but it can extract useful components with very high concentration and few impurities (the impurities will not have a great taste). Therefore, when we smell a cosmetic, its taste is fresh and elegant, even tasteless, then the source of its ingredients and raw materials is very reliable (even if it is extracted from minerals, the extraction concentration is very high).

2. Look at the packaging.

Sisters, don't get me wrong, it's not a matter of exquisite packaging. As I mentioned above, the ingredients of many cosmetics are extracted from plants, and many cosmetics have added many precious plants and traditional Chinese medicine ingredients to increase their efficacy. For example, ginseng, pearls, aloe and so on, these plant components are really "delicate", they are mostly unsaturated organic substances, unstable, and will be added or decomposed when the environment permits, which is what we usually call deterioration. What can make them go bad? Only the substances they come into contact with are organic substances, which can react with them at the same time-plastic bottles for packaging. (I won't elaborate on the reaction of the two people here, there are too many. Therefore, the cosmetics with good ingredients we usually see are packed in glass bottles (glass is inorganic). When I see a cosmetic in the future, no matter what plants and ginseng are advertised by the merchants, if they are in plastic packaging, nine times out of ten these ingredients do not exist. At most, it is glycerin (moisturizing)+polyol (moisturizing)+perfume.

1, acid-base test

Tools: a glass of water, PH test paper, facial cleanser to be tested, beauty soap, etc.

Methods: Dip the PH test paper in water and rub it on the beauty soap, facial cleanser and facial cleanser to compare the PH values. If it is between 4.5 and 6.5, it is a good product.

If it is found to be alkaline, please stop using it as soon as possible, because alkaline products will destroy our sebum membrane. Although it feels that the skin is not greasy, long-term use will cause skin moisture loss and easily cause adverse reactions such as pigmentation and wrinkles. PH acid-base test is suitable for any cosmetics.

2. Toner for shrinking pores

The function of toner is to clean, moisturize and shrink pores. However, a lot of toner on the market contains alcohol, which shrinks pores through the contractility of alcohol. Alcohol can diminish inflammation and kill bacteria, but its fatal weakness lies in its strong volatility. When applied to the face, it will take away the moisture of the skin, but it will make the skin dry. Long-term use of alcoholic products will make the face dull and rough.

Test method: It is difficult to detect, because it will burn only when the alcohol concentration reaches 43%. Generally, toner can't reach the degree of burn, but you can test it on your skin to see if it is irritating. Outside the ear and inside the upper arm.

3. Exfoliating products

Our skin is divided into epidermis, dermis and subcutaneous tissue, among which epidermis is divided into five layers, namely stratum corneum, transparent layer, granular layer, prickly layer and basal layer. Newborn cells reach the stratum corneum 14 days after the formation of the basal layer, and die and fall off after the stratum corneum (epidermis) 14 days. If the body function and metabolic function are normal, the metabolic cycle of newborn cells is generally 28 days, but with the increase of age, environmental pollution and improper use of cosmetics will affect the metabolic function. In particular, the formation of keratin is easy to block pores, which requires us to take regular care every week.

Exfoliating products are good skin care products, but many products are made of silicon made of glass, which is sharp and will scratch the skin, so manufacturers often use mineral oil for lubrication. Mineral oil is a low-cost and high-stability processed product extracted from petroleum. Because the particles are large, they will block pores. If you use this product for a long time, it is easy to hurt your skin and scrape out normal cells undergoing metabolism.

Test method: apply a small amount to the back of the hand and gently rub it to see if there is gloss and large particles in the coated area. If so, please don't use it.

4. Mineral oil test

Our own skin lacks water and oil because it secretes oil. Under normal circumstances, the skin volatilizes water, not oil. Imagine if you put a glass of water and a glass of oil in the sun, you will find that it is water, not oil, that loses its volatilization, and it has not decreased at all. Our skin is the same, we need to drink water!

Tools: lotion or cream, etc. , spoon, candle or alcohol stove.

Test method:-real gold is not afraid of fire.

Light candles or alcohol stoves;

Make a small nail-sized emulsion or cream, put it in a spoon and burn it on the fire;

Is there any emulsion spillage during combustion? This spilled emulsion contains mineral oil which is very harmful to our skin. Please stop using it.

If it is as calm as boiling water, the fragrance of the emulsion finally burned is the same as before, and there is no foreign body residue after burning, and the spoon will not turn yellow. Congratulations! You bought the right product ~

5. Antioxidant test

Iron will be oxidized and rusted in the air, and apples will be oxidized and deformed after being cut. Similarly, skin exposed to air will be oxidized, leading to aging. The process of oxidation is also the process of aging. After the skin is oxidized, spots and wrinkles will appear, and the skin will lose its elasticity.

Test tools: a glass of water, iodine (strong oxidant), facial cleanser.

Test method: drop iodine into a glass of clear water, which will turn yellow-brown and be oxidized by iodine. At this time, squeeze the facial cleanser into the water and stir the facial cleanser to see if the color of the water in the cup has not recovered. Sorry if it is not restored or the color is deepened ~

6. Water solubility test

Test tools: a glass of water, liquid foundation.

Test method: Drop liquid foundation into clear water and stir to see if it is water-soluble. If it is not water-soluble, it will hang on the wall or agglomerate. Please don't continue to use it. This shows that it contains harmful ingredients such as mineral oil and beeswax, which will block pores and hinder the skin from breathing smoothly. Long-term use of this product will cause poor metabolism of the skin, resulting in yellow, dark and unhealthy skin. Then the pores of the skin will become bigger and bigger in the process of struggling to breathe.

7. Moisturizing test (spray)

I don't know if you use spray, such as Shiseido's and Evian's. Spray is to replenish moisture to the skin frequently and conveniently, so we can test whether it has achieved moisturizing effect.

Test tools: clean glass (such as glass window) or mirror, spray, lighter.

Test method: spray the spray on clean glass or mirror to see how long it takes to dry.

The Evian spray I used dried in a short time (unable to moisturize effectively), while the other spray was covered with water droplets a week later.

8. Alcohol test

First of all, a lot of toner on the market contains alcohol to some extent. Why? They rely on the contractility of alcohol to shrink pores. Alcohol can diminish inflammation and kill bacteria, but its fatal weakness lies in its strong volatility. Applying it to the face will take away the moisture on the skin, but it will make the skin dry. If you use alcoholic skin care products for a long time, your face will be dull and rough.

I wonder if you use oral spray? This is just an oral spray with fresh breath. Oral sprays usually contain a high concentration of alcohol. Long-term use will destroy oral mucosa and induce a variety of oral diseases.

Test tools: lighters or candles or alcohol lamps, etc. Hair gel or hairstyle or something.

Test method: light a lighter or candle, and then spray it on the fire to see if it will spray fire, which means that the spray contains more than 43% alcohol. Similarly, products used for hair styling can also be tested in this way, just like magic.

Hope to adopt, thank you.
