Why is tanning true or false
Why is tanning true or false? It turned out to be a trick played by melanin. Melanin has the effect of protecting the skin. If the skin is stimulated by ultraviolet rays, the melanin that originally exists in the body will gather and form a shield to protect the skin against ultraviolet rays. When the danger passes, the melanin will slowly disperse, which forms a false tan. If tanning occurs after three or four days of exposure or sunburn, it is that ultraviolet rays activate melanin mother cells to produce new melanin. This kind of tanning is real, and it is not easy to whiten.
True and false tanning
The appearance of fake tanning indicates that there is more aged melanin scattered in the body. It is impossible to quickly eliminate old melanin with whitening essence or whitening facial mask. It is necessary to strengthen skin metabolism every day and steadily remove old melanin remaining in the stratum corneum. Whitening products containing salicylic acid, fruit acid and a acid derivatives are recommended for continuous use.
If you really get a tan, you have to compete with melanin for time. The formation of new melanin takes about three or four days. During this period, it is the best way to whiten by using blocking and reducing whitening products to preemptively inhibit and neutralize immature melanocytes. However, blocking and reducing whitening products are generally acidic and irritating to the skin. If the skin is sunburned, the first task is to cure the sunburn. At least wait until the redness disappears before using whitening products.
Three ways to save money
1. Distiller’s grains + warm water. Mix the frozen Lees with an appropriate amount of warm water (don’t dilute it too much), and then apply it to your face for 8 minutes. However, try it on your hands first. Allergy is not good!
2. Sweet wine. Take an appropriate amount of sweet wine, and grind the rice inside, then put the compressed facial mask or facial mask paper down to let it absorb, and a whitening facial mask is completed! It’s OK to apply it for about 10-15 minutes. Remember to try it!
3. Sake lotion. The sake we usually drink when we eat Japanese food is also a good helper for whitening. After washing your face, just wipe the sake on your face with cotton wool, and then apply night cream and other maintenance products after it is absorbed.
The above materials are relatively cheap and easy to find. Sisters may as well try them. However, because these contain alcohol, you should try them first, and pay attention to avoiding your eyes.
Whitening principle: because they all contain citric acid, which is similar to pitera yeast, they have whitening effect.
