How to identify the good and bad of a sleeping mask, how to distinguish the good from the bad of a s

The identification method is as follows:

Weight grams: Choose thicker ** contains more essence or nutrients. Pick up a single package of aluminum foil** and take a look, too light means that the paper is relatively thin, and the essence content is also less

Observe the texture, color, viscosity, and ductility of the product, and the thickness is uniform.

Tailoring – Lay flat on the black version and get up close to the overall cut, local cut.

Face fit - spread ** on the face to see if ** can fit the face completely, and observe whether the corners can be completely conformed.

Medium ups and downs: Pour the essence into a glass of water.

1: ** is transparent is best, with color or milky white, with pigment or emulsifier inside.

2: The **essence dissolved in water is the best**, floating on the surface of the water, sticking to the edge of the cup, and sinking to the bottom of the cup, it is not good**.

Ultraviolet lamp test fluorescent**.

In the dark, use ultraviolet lamps (small flashlights, mobile phones with flashlights, etc.) to irradiate **, check whether they emit light blue fluorescence, if there is**There is phosphor doped inside, phosphor is harmful to**, this is poor**, on the contrary, there is no fluorescent color is good**.

5PH Test Acid-Base:

Use the pH test strip to the side, and then use a color card to control the pH, 0 to 6 is acidic, 7 is neutral, and 8 to 14 is alkaline. Only 5-7 are safe and can be used for a long time.

The reason why it has the effect of improving skin texture mainly depends on its closure to the skin, and then applies greater osmotic pressure to the epidermal cells and the intercellular space, so that the active ingredients in the ** can be absorbed. However, the degree of closure is also different according to the different formulas of **, according to the theory of cosmetics; "Dry powder**", "Wet powder**", "Emulsified powder**", "Emulsifying paste**", "Emulsifying film-forming type**", "Film-forming type**".

When applied externally**, the higher the degree of closure, the higher the degree of hydration, reflecting the effect of external increased pressure on cell membrane dialysis. However, the absorption of the outside world is not endless, it will soon form a saturation state, and no matter how long it is, it is useless, which is why in beauty professional treatments, the application time is usually not higher than 15 minutes.

Therefore, "sleep" is not scientific, if it is applied for too long, it will interfere too much with the normal metabolism of **. Loss of excretory function will be a pathological **, and even cause a disorder of metabolism in subcutaneous tissues. "Sleep**", it's better to use it with caution!

The success of an individual person does not represent a shift in the basic theory of science!!

First of all, you can't feel too tight when you wake up in the morning. Secondly, it is best to choose the kind of plant herb**, or the kind of gel**

1. Look at the texture, the texture is uniform and transparent. Formulas with cloudy textures and different colors are unstable, so it is recommended that you do not use them.

2. Smell the smell, a good sleep ** will not use a lot of flavor. Because the essence has thorns.

Irritation, easy to produce allergies, so a good sleep ** taste should be light, too strong and too strong the taste is not good for **.

3. The absorption effect is also the key factor to distinguish the quality of sleep. If one sleeps.

**It has not been absorbed for a long time, and it is sticky on the face, it must not be a good sleep**. A good sleep should be refreshing and well absorbed, and it will be fully absorbed by a gentle massage, and the clothes and quilts that will not stick will be all there.

4. Good sleep**When you wash your face the next morning, you will feel that there is a thin film left on your face, because a good sleep** has moisturizing and water-locking ingredients left on the **table.

layer, if there is no such thin film to prove that the water-locking effect of sleep ** is average.

Secondly, look at the shape Most of the ** is a whole face that can be pasted There are also better ones who want to stick the face all over the face, which is composed of two parts. So which one is better, in fact, after trying it, there will be an obvious feeling: the adsorption of the two parts is better, and the coverage area is larger.

Look at the viscosity Or take a few dollars and a dozen dollars compared The viscosity is not the same Good**is to reduce the viscosity as much as possible Not after applying ** The face is still slimy but basically dry Because in addition to volatilization, it is well absorbed.

Look at the ingredients **There are many types, such as anti-wrinkle, acne, whitening, etc. For these different effects**There will be a clear mark on the outer packaging There are special ingredients that can achieve these effects The others are auxiliary.

Once you've seen the main ingredients, you can look them up on the Internet to see if they really meet the requirements.
