GentleMax Pro Plus delivers two wavelengths—755 nm alexandrite and 1064 nm Nd:YAG—to the target depth. The 755 nm wavelength is highly absorbed by melanin, targeting hair roots and superficial pigmentation, while the 1064 nm wavelength penetrates deeper to act on thicker hair roots and blood vessels. The absorbed light is converted to heat, affecting only the target, while a simultaneously sprayed coolant protects the epidermis. As a result, you can expect hair reduction and improvement in spots and redness.
