At present, there are two main forms of medical hair removal, namely laser hair removal and pulsed light hair removal. Laser hair removal is mainly discussed here, which has been proved to be effective for hair removal.
Most medical cosmetology is introduced through the FDA’s Israeli laser 808nm hair remover. Compared with other hair removal instruments, it can control energy and has high safety. It can be applied to any part of hair, including light hair color (80nm), and of course, it can be applied to any part of hair, including light hair color and black color (80nm).
To understand the principle of laser hair removal, we need to understand the growth characteristics of hair.
The hair cycle is generally divided into growth period (2-7 years), regression period (2-4 weeks) and rest period (about 3 months). The hair of different parts has different growth cycles, and the interval of each treatment is also different. If the hair on the hairline has a relatively short rest period, it can be separated by 1 month; The hair rest period of trunk and limbs is relatively long, so the treatment interval is about 2 months.
Laser can destroy 75% of the hair in the growth period and 25% of the hair in the degenerative period, which is basically ineffective for the hair in the dormant period. A complete course of laser hair removal covers at least 4 months of dormancy, that is, 4 to 6 times of laser hair removal in about 5 to 7 months, so as to obtain the ideal effect.
Before laser hair removal, we should first understand that hair removal is not achieved overnight. We need to treat it in batches and times according to individual differences. During hair removal, in order to protect the skin, focusing on the beam, the gel will generally be applied to improve the efficiency of hair removal. Moreover, the advantage of 808 semiconductor freezing point hair removal is that the pain is weak and the process is mild.
