Treatment Principle:

The Q-switched laser therapy device utilizes the principle of photodisruption, where through millisecond or microsecond ultra-pulse durations, the laser instantly penetrates the epidermis to reach

the deeper layers of the skin, causing the internal pigment particles to shatter instantaneously. The shattered pigment particles are then engulfed by the body's macrophages and gradually transported away. Since lasers of specific wavelengths can pass through the epidermis and dermis to reach the pigmented lesion tissues, they only act on the pigment particles, resulting in minimal or no damage to the epidermis and no significant harm to the skin texture, thus leaving no scars. By emitting high-energy laser pulses instantaneously, the device effectively shatters and removes pigments in the lesion tissues. The corresponding pigment clusters rapidly expand due to heat and are instantly disrupted and broken apart. Most or all of the epidermal pigment clusters are immediately ejected from the body, while some dermal pigment clusters break into fine particles that can be phagocytosed by macrophages. After being engulfed by macrophages, they are eventually eliminated from the body through the lymphatic system. The chromophores in the lesion tissues gradually fade until they disappear, while the surrounding normal skin tissues, which do not absorb the fixed wavelength laser, experience almost no damage.

Treatment Scope:

Primarily used for removing pigmented skin lesions, pigmentation caused by mixed pigments, and traumatic pigmentation.

1. Various Moles and Spots:

Nevus of Ota, Ito's nevus, Mongolian spot, zygomatic freckle-like nevus, café-au-lait spot, seborrheic keratosis, speckled lentiginous nevus, junctional nevus.

2..Tattoos, Eyebrow Tattoos:

Tattoos, eyebrow tattoos, eyeliner tattoos, lip liner tattoos, and traumatic tattoos, among other pigmented skin lesions.

Feature One:

Dynamic laser with more concentrated energy and stronger selective destruction of pigment particles: Ordinary solid-state pulsed lasers output light pulses with relaxation oscillation phenomena, resulting in a wide laser pulse width and peak power only at the kilowatt level, which fails to achieve ideal clinical treatment effects. The Q-switched laser can convert most of the stored upper-level particle energy into laser energy within an extremely short time, outputting a giant laser pulse with megawatt-level peak power, instantly shattering the pigment particles in the skin to achieve the desired therapeutic outcome.
