What is the principle of a freezing point hair removal device?

Generally, hair removal devices using "ice point" technology work by emitting specific wavelengths of light through laser or photonic technology. This light is absorbed by melanin cells within the hair follicles, damaging them and rendering the follicles inactive, thereby preventing hair regrowth and achieving the goal of hair removal. The detailed mechanism is as follows:

The ice point hair removal device contains a light source that emits specific wavelengths of light, typically in the infrared spectrum. These light waves can penetrate the skin and reach the deeper tissue layers where hair follicles reside. As the light passes through the skin, it is absorbed by the melanin in the hair follicles. The absorbed light energy is then converted into heat, causing the temperature within the follicles to rise. When the temperature reaches a certain level, the cellular structures inside the hair follicles are damaged—particularly those cells responsible for hair growth. Once these structures are destroyed, the follicles become inactive and can no longer produce new hair. This explains why ice point hair removal devices can achieve long-term hair reduction.

However, if the light energy is too high or treatments are performed too frequently, side effects such as skin burns or hyperpigmentation may occur. Therefore, it is advisable to consult a qualified physician or dermatologist before using an ice point hair removal device.
