Skincare common senseWhat is oxidation and what is skin oxidation?

Oxidant – Oxidation.

Oxidation is the biggest threat to skin aging, unhealthy diet, sun exposure, stress, environmental pollution, etc., can make the skin flood of free radicals, resulting in dull complexion, lack of water and other oxidative phenomena. They are all the "culprits" of oxidation in the body. Therefore, whether from the health level or from the skin care level, we need to pay attention to antioxidants in our daily life.

The body's antioxidants are either synthesized by themselves or supplied by food [1]. Enzymes and non-enzymatic antioxidants play a vital role in protecting against exercise-induced peroxidative damage. Supplementation of antioxidants is beneficial to the exercise body to reduce the production of free radicals or accelerate their scavenging, so as to fight the free radicals, so it is beneficial to the health of both the general public and athletes, and may delay the occurrence of exercise-induced fatigue and accelerate physical recovery.

Older physically active people take antioxidants better than younger people.

The skin is the carrier of nutrients, and it is also the channel for nutrients to penetrate. However, the absorption capacity of the skin is limited, and the skin type does not match the type of skin care products, which will make the nutrients stay on the surface of the skin, causing "** oxidation".

Consequences of skin oxidation: A simple metaphor is like exposing a peeled apple to a period of time, and the apple will produce oxidation that turns yellow and dry. The oxidation problem of the skin is the same as that of peeling apples, but the yellowing, dryness, roughness and aging of the skin cannot be seen with the naked eye in a short period of time, and it is often too late to remedy the oxidation and aging problems of the skin when the skin oxidation and aging problems appear on the surface of the skin.

Therefore, even if your skin is still young, but remember, skin maintenance is like good health, prevention must be better than **, therefore, pay attention to sun protection and antioxidant in the morning and evening, you can reserve a good youthful capital for the skin, aging, spots, sagging...Naturally, it will stay away from you.

What does oxidation mean?

In the normal metabolism of life in the human body, some oxygen free radicals are produced in the cells. This leads to the emergence of ** oxidation phenomenon. Therefore, people believe that free radicals in the body are the cause of oxidation and gradual aging.

Our daily continuous contact with the outside world will cause our body to produce free radicals, especially people with serious environmental pollution and poor working environment, who are more likely to produce a large number of free radicals. Therefore, in daily life, we should pay attention to the protection of ourselves. It is recommended that people with poor living and working environments can carry masks when they go out to isolate pollutants.

And the ultraviolet rays in the sun can also promote the production of free radicals, so in the summer, it is also necessary to do a good job of sun protection, such as wearing sunscreen, using sunglasses, parasols and drinking water.

Maintaining a good routine is also very helpful for us to resist oxidation, especially to maintain sufficient sleep and achieve a combination of work and rest. We all know that if a person does not get enough sleep, it is easy to get tired the next day, in fact, lack of sleep is also very bad for the body's antioxidants. The time of sleep every day is actually the time for the body to adjust and recover, if especially 11-2 o'clock is the most vigorous time of human metabolism, if you do not sleep at this time, it will have an adverse impact on the body.

Therefore, if we want to resist oxidation, we should maintain a good routine and rest habits, so as to help the body resist oxidation.

Answer: Long-term or excessive direct ultraviolet radiation causes **peroxidation, first of all, you can condition the body, eat some effective nutrients for yourself, and secondly, maintain an optimistic mood, quit irritability, less anger and less sadness, and have enough sleep is also essential, sleep enough for 8 hours a day, and then you can apply **promote** water content, twice a week, avoid direct sunlight, and do a good job of sun protection.

**Oxidation is mainly manifested as dull yellow and dull face, with long wrinkles. Spots. As people get older, they become more oxidized.

Skin oxidation is an excess of free radicals on the skin. Too many free radicals attack skin cells, causing body aging, organ and tissue mutations, skin aging and decreased immunity.

The most important feature of oxidized is the yellowing of the face, the increase of spots and blemishes, just like the "yellowing" of apples after oxidation and the "rusting" of steel after oxidation. If your ** slowly becomes tarnished because dryness becomes no sense of transparency; There are even a lot of dark spots, so this is a sign of skin oxidation.

Generally, skin care products can be used up after about half a year, but sometimes we don't use a skin care product very often, so this skin care product will oxidize after a long time. I don't know if you know about cosmetic oxidation. What does cosmetic oxidation mean?

Can cosmetics still be used if they are oxidized? Let's take a look at the answers to these two questions.

1. Cosmetic oxidation refers to the oxidation reaction of the ingredients in cosmetics in contact with the air, and the bacteria in the air come into contact with the surface of the product, affecting the use effect of cosmetics. Although cosmetics can be used within the shelf life, cosmetics still have a "freshness period", which refers to the degree of oxidation of cosmetics.

2. Oxidation of cosmetics does not mean that they cannot be used, but the effect of cosmetics is not as good as when it was first opened. The long storage time of cosmetics, the quality of the environment in which cosmetics are placed and the way cosmetics are used may affect the use effect of cosmetics, so it is recommended to change the bottle cap in time when using cosmetics to avoid bacteria in the air from entering the product. And use a cosmetic product in time, don't leave it for too long after opening it.
