How to preserve skin care products?

Good skin care products have the function of beauty beauty, which helps to maintain skin elasticity. Regular use of skin care products can keep people young and beautiful and delay skin aging. But if it is a deteriorated skin care product, it has no effect on the skin. May be harmful. So how to preserve skin care products? What should I pay attention to when storing skin care products?

1, pay attention to the storage of skin care products.

1, thermal protection

Skin care products should not be stored in a place with high temperature, because high temperature will not only volatilize the water in skin care products, dry the cosmetic cream, but also separate the oil and water in the cream and deteriorate it.

Step 2 protect yourself from the sun

Skin care products should not be stored in direct sunlight or light, because when skin care products are exposed to direct sunlight or light, water will evaporate, some ingredients will lose their efficacy, and even chemical changes will occur, reducing their efficacy.

3, antifreeze

Skin care products are easy to freeze and crack when stored in cold places, and oil-water separation will occur after thawing, which will thicken and harden some of them and irritate the skin.

4. Moisture-proof

Some skin care products contain a lot of protein and honey, which are easy to get moldy after getting wet. Some are packed in glass bottles with iron lids. The iron cover is easy to rust, corrode cosmetics and deteriorate after being wetted.

5. Pollution prevention and control

Although preservatives have been added to skin care products to prevent the products from being contaminated and deteriorated, it is still impossible to prevent them from happening. If there are bacteria in it, it will harm the skin. Therefore, skin care products must be tightened in time after use to prevent bacteria from invading and multiplying. In addition, once skin care products are used, such as creams and lotions, they can't be put back in the bottle to avoid pollution.

2, skin care products storage misunderstanding

Myth 1: Toilets are cold and easy to store.

In fact, some skin care products contain a lot of protein, which is easy to get moldy after getting wet. Some are packed in glass bottles with iron lids. The iron cover is easy to rust, corrode cosmetics and deteriorate after being wetted. So wet toilets are not suitable for storing skin care products.

Myth 2: Keeping the refrigerator alive is the best way.

In fact, the most suitable temperature for preserving cosmetics is about 15℃, and the temperature of refrigerator will be lower than this temperature, and the emulsified structure in cosmetics will be destroyed in the low temperature environment. Some liquid skin care products can be stored in the refrigerator, but it is best not to put creams, perfumes and essential oils in the refrigerator.

3. Beauty and skin care in autumn

Due to the large temperature difference in autumn, the cold and hot weather reduces the skin resistance and is vulnerable to bacterial infection. Therefore, autumn skin care should first focus on cleaning the skin. Sunscreen facial cleanser with strong sterilization, good cleaning effect and weak acidity is preferred.

Secondly, we should take into account the temperature difference between morning and evening. During the day, you should use skin care products that are refreshing and sunscreen in summer, such as various sunscreens and moisturizing honey. Choose moisturizing skin care products at night, such as night cream and nutritional cream. Due to the dry temperature in autumn, sebaceous gland oil secretion decreases, water evaporates quickly, and the face is prone to tension. Therefore, in autumn, in addition to using alcohol-containing emulsion and moisturizing milk, we should also pay attention to the moisturizing care of the stratum corneum.

After September, autumn is getting stronger, and people often ignore the existence of ultraviolet rays. In fact, the ultraviolet rays in early autumn are quite strong. During this period, the skin is more vulnerable to the sun, and tanned skin is generally not easy to fade. The reason is that because of the cold weather, the metabolism of the skin begins to slow down, so you should also wear sunscreen when you go out.

The stability and service life of skin care products are limited. If skin problems occur due to improper storage, it will not be worth the loss, so it is necessary to store and use skin care products correctly.

Gently press the U area of the face with the palm of your hand, from bottom to top and from outside to inside, to ensure that the essence is completely absorbed. T-zone repeats in the same way. Finally, gently pat the facial skin with the fingertips, and the pressure is 100, which is one group and can be performed in three groups.

4, moisturizing: choose different moisturizing skin care products according to your skin. If the skin is dry in autumn and winter, use cream, day cream and night cream. Moist skin in spring and summer. Just use milk. This is the last step when the skin care mask is not enough at night!

6. Sunscreen: Sunscreen should be selected according to your own needs and the SPF and PA values of sunscreen. The efficacy time of sunscreen depends on SPF value. Take SPF 15 as an example, its onset time is (15× 10 min = 150 min), that is, SPF 15. It is not that the longer the time, the better, because the longer the time, the heavier the burden on the skin.
