Diode laser hair removal is based on the principle of selective photothermolysis:
*The laser precisely targets melanin in hair follicles. Melanin absorbs light energy and converts it into heat energy.
*The heat energy raises the temperature of hair follicles to 60–70°C, destroying the dermal papilla and germinal epithelium, so that hair loses its regenerative ability.
*Equipped with an epidermal cooling system (sapphire cooling tip), it protects the epidermis during treatment, reducing pain and the risk of thermal injury.

Based on the photoacoustic effect, ultra-short pulse laser precisely targets pigmented tissues in the epidermis and dermis. It generates instant micro-explosive force to shatter melanin particles into metabolizable micro-fragments, which are then naturally eliminated via the human lymphatic system, achieving highly effective removal of pigmented skin lesions.

Intense Pulsed Light (IPL) is a broad‑spectrum incoherent light technology. Based on the principle of selective photothermolysis, it precisely targets pigment particles, hemoglobin, and collagen fibers in the skin. On one hand, it breaks down pigments and closes abnormally dilated capillaries to improve pigmentation and redness; on the other hand, it stimulates the regeneration and remodeling of dermal collagen, achieving multiple effects such as skin rejuvenation and anti‑aging.

Fractional laser is an advanced skin treatment technology based on the principle of focal photothermolysis. A single laser beam is split into numerous micro-fractional spots with diameters ranging from tens to hundreds of microns by a specialized optical system. These spots act on the skin precisely in an array pattern, creating a large number of controllable Microthermal Zones (MTZs) in the epidermis and dermis. These microthermal zones are surrounded by adjacent healthy normal skin tissue, which greatly reduces overall trauma. This process not only effectively smooths depressions and fades lines, but also deeply enhances skin firmness and elasticity.

Dual Wavelength Laser can emit Nd:YAG (1064nm) and Alexandrite (755nm) wavelengths with synchronized and adjustable proportions:
*Alexandrite 755nm long pulse wavelength due to the high melanin absorption it is effective for hair removal and pigmented lesions treatment;
*Nd:YAG 1064nm long pulse wavelength rejuvenate skin by stimulating the dermis layer, effectively treating vascular lesions.
