1. The oxygen content of the skin decreases, all due to aging darkening. With age, the lung capacity decreases and the amount of oxygen taken up by breathing decreases. According to medical reports, the oxygen content of the skin of 25–30 years old is only 35% of the skin of newborn babies.
2. The decrease of oxygen content in the skin will cause the blood flow to be diffuse, the supply of nutrients will be insufficient, the production of subcutaneous collagen will be slowed down, and the cells will begin to decay and react on the skin, which will cause aging, dullness, slack, dark circles and other conditions.
The skin contains enough oxygen to have smooth and smooth keratin. About 21% of the air you breathe every day is oxygen, and 7% of the oxygen inhaled into the lungs will be repaired and grown by the whole skin with oxygen, which will make the metabolism rule, destroy bacteria, accelerate the circulation, remove toxins, and make the skin red and elastic.
4. The decrease in skin oxygen content is due to the diversion of oxygen for other purposes, and how oxygen is distributed and used by body organs is also the key to affecting skin oxygen content. For example, diseased parts of the body are allocated more oxygen. If there is no major damage to the skin, it will be the last to get oxygen, so any condition in the body will affect the oxygen content of the skin.
