Can liquid foundation be kept in the refrigerator in summer? What are the methods of foundation preservation?

The texture of many cosmetics may change in summer, so we should pay attention to the correct preservation of cosmetics in summer. If the liquid foundation is not stored properly in summer, there will be layered changes, which will affect the use effect. So, can liquid foundation be stored in the refrigerator in summer? What are the methods of foundation preservation?

1. Can the liquid foundation be put in the refrigerator?

Many skin care products, including some make-up products, are not well preserved in hot weather, so many people keep these daily necessities at low temperature, such as the refrigerator. But liquid foundation, for example, is a relatively liquid makeup product. Can you keep it in the refrigerator?

2, it is best not to put the refrigerator.

Generally, we recommend that liquid foundation should not be stored in the refrigerator. First of all, skin care products and cosmetics that can be stored in the refrigerator are products that are relatively stable at low temperature and their state will not change, while liquid foundation is not. When the temperature is below zero, the liquid foundation may freeze; Moreover, the liquid foundation itself is not so heat-resistant, and the liquid foundation can remain stable at high temperature.

3. Liquid foundation will be divided into two layers.

Generally, liquid foundation can be divided into two layers after standing at room temperature for one to two weeks. We can clearly see that the upper layer is water layer and the lower layer is powder layer. Because the liquid foundation itself is a liquid cosmetic made of foundation, that is, it consists of two phases, one is a water phase and the other is a solid phase, so if it is not shaken frequently, it will be completely pulverized, but just shake it evenly after the powder layer.

4, can be stored at room temperature.

Generally, the liquid foundation we use can be stored at room temperature. First of all, the liquid foundation will be mixed more evenly at room temperature, but the powder layer may be more serious at low temperature; Furthermore, at room temperature, the liquid foundation will not deteriorate, even when the temperature is the highest in summer, because the liquid foundation itself is not a make-up such as a paste, nor an unstable skin care product such as a mask, and the texture and composition of the liquid foundation are stable.

5. What should I do if the liquid foundation is layered?

Don't use it

The top layer is nothing more than the oil in the liquid foundation, which is the result of oxidation reaction when the product comes into contact with air and sunlight. The appearance of this oil layer shows that the chemical composition structure in the liquid foundation has changed and lost its original effect. Even if the extruded product doesn't seem to change, its force on the skin must have changed-either the adhesion is greatly reduced, or the particles will block pores or cause allergies. In short, there is no need to do so. Besides liquid foundation, sunscreen and lotion should also be discarded. To avoid this situation, be sure to tighten the bottle cap after each use.

6. What is the shelf life of liquid foundation?

Foundation: 6 months to 2 years

Bottled foundation has a shelf life of about 6 months, and air cushion foundation can be used for 1-2 years. After using this product, the foundation usually "can't stop at all" because you have adapted to the even skin tone it can create. Therefore, after the foundation expires, you should buy a new one immediately, just to "take this opportunity" to try new products.

7, summer liquid foundation preservation method

The types of foundation can be divided into powder cake, loose powder and liquid foundation. So pay attention to it according to its different States when saving.

Don't expose the solid powder cake in the sun during storage to avoid cracks in the powder cake.

When storing loose powder, do not soak it in water. The soaked loose powder is not only easy to deteriorate, but also inconvenient to use.

Liquid foundation should be clean and hygienic. After each use, the cotton pad with foundation must be cleaned to avoid bringing bacteria into the liquid foundation.

8. How to use liquid foundation

(1) Apply liquid foundation by hand.

Step 1: After the skin care step, take a proper amount of liquid foundation and dip it with your middle finger and ring finger.

Step 2: Apply foundation evenly on the forehead, chin, cheeks and nose. Spread out from five points until the liquid foundation blends into the skin.

Step 3: The skin around the eyes is very thin, so don't apply too thick liquid foundation, otherwise wrinkles will easily grow. When applying foundation under the eyes, look up with your eyes, and then apply the foundation evenly from the inside to the outside of the eyes by gentle pressure.

Step 4: The liquid foundation of facial skin has been applied evenly, but the nose can't be ignored. Take a little liquid foundation on the bridge of the nose and push it horizontally by hand, which will make the liquid foundation on the nose wing thinner and create a translucent feeling.

(2) Apply liquid foundation with a sponge.

Step 1: Apply a little foundation to your forehead, chin, cheeks and nose.

Step 2: Choose a clean gourd-shaped sponge. The large one is usually used to wipe cheeks and forehead. Sharp ones are used to wipe the nose and chin.

Step 3: Take some liquid foundation at both ends of the nose wing, because the nose wing is easy to turn red, so you need to coat it with a pointed sponge.

Step 4: Press the whole face with a big sponge once to make the makeup look more docile.

(3) Apply liquid foundation with a brush.

Step 1: Squeeze the foundation on the back of your hand, and then dip it evenly with a brush.

Step 2: Put one third of the hair of the brush on the skin, gesture at a 45-degree angle, and go straight back and forth.

Step 3: Brush your nose. The nose is the easiest place to get oil, so pay special attention when applying liquid foundation, and the brush head should be upright, so as to skillfully take care of small parts.

Step 4: Brush your forehead. Actually, you can brush your forehead first Brush evenly from the center of the forehead to both sides, you can brush it several times, and it is best to brush it near the bun to avoid uneven foundation.

Step 5: If there are obvious flaws in some parts of the face, it is recommended to gently brush another layer with a brush to cover up the flaws.
