Human aging is related to free radicals, anti-aging should do this well!
We often hear the saying "fight against free radicals and delay aging". Some friends have doubts about this. Do free radicals really affect human aging? Well, first of all, we must understand how free radicals make people age!
From a chemical point of view, a free radical is an oxygen molecule lacking an electron. It is very active and can easily react with other substances. This process is called "oxidation".
The aging process of the human body is like oxidation, and the substances that make the cells in the body "rust" are free radicals. Under normal circumstances, the free radicals in the human body are in balance, that is, the production and removal are balanced.
However, problems such as air pollution, workplace pressure, socializing with alcohol and tobacco, irregular diet, and staying up late will all cause stress reactions on the skin, resulting in the generation of a large number of free radicals. The skin is the outermost protective line. Free radicals first attack the skin cell membrane, disturbing the normal skin function, causing oxidative stress, and thus skin oxidation.
When skin cells are oxidized, free radicals will destroy the collagen of the skin, causing the skin to lose its elasticity and luster, the complexion will become dull and sallow, wrinkles will appear, and even cell tissues will be destroyed.
You know, 80% of skin aging problems are caused by free radicals. Free radicals have strong activity and are very destructive to the human body. And many scientific studies have shown that our body cells are attacked by it at least 73,000 times a day. Free radicals can cause cell aging and DNA mutation. Therefore, many anti-aging skin care methods are to eliminate excess free radicals and prevent the skin from being harmed by them!
Fight free radicals, start with skin antioxidant
As we age, our body's ability to repair free radicals decreases. If the body fails to resist oxidation in time, the cells will start to be damaged, and even cause diseases, seriously endangering people's health. To fight against free radicals, we should start with skin anti-oxidation, and these methods are hidden in our daily life!
- Take sun protection measures
In fact, the primary cause of premature aging of the facial skin of the human body is ultraviolet radiation. Excessive ultraviolet light irradiation on the skin will increase the free radicals in the human skin, resulting in free radical damage.
Therefore, in this hot summer, it is recommended that you apply some sunscreen, open an umbrella or wear a sun hat when going out.
- Reasonable diet
You should eat more fresh and healthy foods rich in antioxidants, such as: tomatoes, broccoli, blueberries, pomegranates, grapes, red dragon fruit, winter dates, green leafy vegetables, green tea, soybeans, nuts, etc.
Especially darker fruits and vegetables contain a lot of vitamin C, and nuts contain a lot of vitamin E, both of which are "free radical scavengers", which can neutralize the oxidation of free radicals and block their chain reaction.
- Avoid alcohol and tobacco
Scientific research shows that smoking is one of the fastest ways to generate free radicals. Every puff of cigarette will produce more than 100,000 free radicals, and even accelerate the growth of cancer cells, especially lung cancer. In order to fight against the harmful substances inhaled when smoking, the human body will consume more vitamin C than usual. A cigarette can "destroy" 25 to 100 mg of vitamin C.
We also want to keep alcohol to a minimum, because when the liver processes the toxins in alcohol, it produces more free radicals than the body's intake of antioxidants can handle. This leads to a reaction called oxidative stress, that is, the imbalance between oxidation and anti-oxidation in the body, and people naturally age faster.
Skin aging is a long process, and the key to maintaining healthy skin is to develop healthy and good living habits.
