Selective photothermolysis

Laser energy is absorbed by melanin in the hair and transferred to the follicle as heat. The device must deliver enough energy to the right depth without overheating the skin surface.

That is why professional hair removal depends on stable power, contact cooling and flexible settings for the treatment area, hair density and client phototype.

Why several wavelengths are used

808 nm is considered a universal wavelength, but different hair types and skin phototypes need different depths and absorption profiles. 755 nm is useful for more superficial and finer hair, while 1064 nm is deeper and often preferred for darker phototypes.

Multi-wavelength systems help a salon work with a broader client base than single-wavelength machines, especially when clients differ in skin and hair type.

Cooling and treatment course

Cooling protects the epidermis and improves comfort. It also helps keep parameters stable when the device is used continuously during a busy schedule.

A course is needed because hairs are in different growth phases. Laser hair removal works best in the active phase, so results are built over several sessions with intervals.
