The wavelength is further compressed between 690nm and 1200nm, making treatment more precise.

Furthermore, it is a rectangular square wave with a uniform and stable pulse energy, which greatly enhances the treatment effect.

In addition, it eliminates energy peaks in the treatment energy, improving safety and reducing side effects.

Laser energy is high and stable. The laser is a single wavelength, which can be precisely targeted at the target cells, with greater and more stable energy, shorter operation time and better treatment results, whereas The IPL OPT is a long pulse spectrum with a wider range of wavelengths, and the energy is easily absorbed by the epidermis, with more energy lost and very little energy actually reaching the pigment cells. As a result, the treatment is not as effective.

Laser treatment is more effective and safer. The laser is able to penetrate the epidermis to reach the hair follicle with precision and destroy the pigment cells completely, resulting in permanent hair removal. Moreover, the laser is rarely absorbed by other parts of the body, making it safer and with fewer side effects.  In contrast, IPL SHR energy is mostly absorbed by the surface skin and the treatment session requires more.

The laser operation can be controlled. The laser wavelength can be adjusted for different skin types and hair colours, allowing for a more user-friendly and targeted treatment. IPL, on the other hand, is not controllable and can easily lead to medical accidents. It is recommended to choose an experienced doctor to operate it.
