1, the sunshine is naturally beautiful and black.
Proper sunbathing is the most affordable way to get a tan, which can make the skin appear healthy wheat color, at the same time, it can also make the body produce vitamin D and promote the absorption of calcium. However, because there are many complicated rays in the sun, it is easy to cause peeling and sunburn, and long-term exposure to the sun will lead to skin cancer and other problems.
This has been proved in related studies. Americans have the highest probability of skin cancer in the world, which is related to their lifestyle and geographical location.
2, indoor tanning machine tanning
The biggest difference between tanning machine and natural tanning machine is that tanning machine imitates natural light, but artificially eliminates harmful light waves in the sun, and only keeps beneficial light waves (such as the light with 80%UVA+20%UVB in the beautiful Kangmei tanning machine), which can effectively reach the deep skin and promote the production and fixation of melanin.
While melanin is formed in the deep skin, it also stimulates the vitality of more cells. After tanning, the tanning machine is not only thinner, stronger and healthier, but also has the following functions:
Charm doubled: ultraviolet rays (B waves) can increase the secretion of various hormones in the body, making people feel strong and confident.
Strengthen muscles: promote vitamin D3 production and calcium synthesis, enhance reflex and motor nerves, and strengthen muscles and bones.
Strengthen bones: promote the production of vitamin D3 and the absorption of calcium, strengthen bones and teeth, and avoid osteoporosis.
Enhance physical fitness: ultraviolet (B wave) can enhance the body's immunity and enhance the body's resistance.
Lose weight: it can promote cell metabolism and burn excess fat and calories.
Anti-aging beauty: promote skin blood circulation and cell metabolism, make skin smooth and elastic.
Relieve fatigue: promote perspiration, eliminate the fatigue substance in cells-lactic acid, and relieve fatigue and stress.
Happy mood: promote the secretion of serotonin, make people happy and improve their thinking ability.
So tanning is bad for your health? Under normal circumstances, there is no harm. You just need to control the frequency and don't be exposed to the sun for a long time.
Tanning machine tanning 2 steps
Indoor body tanning is divided into two steps, one is coloring period: the process of skin from white to deep. In order to ensure the coloring effect, the pre-drying time is generally 10- 15 minutes, 1-2 days, so that melanin can be deposited on the skin. Then enter the maintenance period, which is to maintain skin color. In order to avoid metabolism and lighten the skin, you can 1-2 Qian Zhou once.
Knowledge expansion
The main reason for tanning is that UVA and UVB in ultraviolet rays are at work.
UVA is a kind of ray light with long wavelength and strong penetrating power, which can penetrate the surface layer of skin and go deep into the tissue below dermis, so UVA can form melanin in the deep layer of skin and persist.
UVB rays are high-intensity rays, which can quickly generate melanin in subcutaneous tissue, but the melanin formed by UVB rays has poor durability and is easy to get sunburned.
The light in the tanning machine effectively combines the best ratio of UVA and UVB through professional technology, which not only effectively tanning, but also ensures that the skin will not be easily sunburned.
