CO2 LASER MACHINE FRACTIONAL
Co2 laser treatment principle of operation
co2 fractional laser resurfacing is a kind of Ablative factional laser. Fractional laser is also called pixel laser or image beam laser.
Co2 laser uses the principle of focal photothermal action and is well absorbed by water in the skin, which is the main target substance of its action. Water absorbs laser energy and produces a certain degree of thermal damage. The irradiated area will form small columnar epidermal thermal denaturation and necrosis. When the energy density is large enough, the true epidermal tissue can also be vaporized to form positive holes. These MENDS directly stimulate the dermis and initiate the programmed process of skin repair, and the surrounding untreated areas are not damaged.
In injured normal tissues, keratinocytes can crawl quickly, and a large number of stem cells and transient proliferating cells participate in the repair process, so that they can heal quickly. The skin layers are reconstructed: the epidermis is exfoliated; the dermis produces new collagen. It is mainly used for cutting, cauterizing, vaporizing, coagulating and irradiating human tissues to achieve the removal of benign pigmented moles and benign growths on the skin surface; facial rejuvenation (wrinkle removal); the purpose of improving various scars (acne, scars); It can also treat gynecological diseases such as vulvar atrophy, vaginal relaxation, vaginal astringency, and stress urinary incontinence.
