But in general, there is no significant difference between laser hair removal and intense pulsed light hair removal efficiency. In addition, for the light-colored hair of European and American whites, exogenous color base and photosensitizer can be applied to increase the hair removal efficiency. Freezing point hair removal often refers to semiconductor laser hair removal with cooling device, which protects the skin and reduces pain by maintaining the temperature at about 4 degrees.

In addition, hair and sweat glands seem to be related to sweat, but they are only neighbors, not husband and wife or father and son. The palm of your hand is hairless, and you can still sweat like pulp. Will the fire at the gate hurt the fish in the pool? This is the most critical and highest place of laser hair removal technology. By setting the time of thermal injury, light and heat are confined in hair follicles to prevent excessive damage to sweat glands and other tissues, so sweating will not be affected.
Because the hair growth cycle of different parts is different, the interval time is also different. Generally speaking, the head and face are 4-6 weeks and the trunk is 8 weeks. The last few times can be extended appropriately. What if the time is shorter than this? Hair follicles are not fully recovered, small in size, easy to escape the damage of light, and the hair removal efficiency is reduced.
