Please note that this seller's product is not an original, but an analogue of the original product. Principle: Fractional Laser CO2 resurfacing delivers laser in fractional manner into the skin while leaving the untreated surrounding areas intact. Laser creates microscopic thermal dot on surface and performs within tissues, offering improve skin tightening, age spots, fine lines, acne scars, stretch marks removal and vulva rejuvenation. The untreated tissue helps to accelerate the healing process and rejuvenate the skin by promoting microcirculation and new cell genesis. Vaginal tightening tube using a three-dimensional lattice technology and 360-degree circular emission perfect combination of technology, to produce 50-70 degrees Celsius in a controlled depth of the vaginal mucosa, stimulate lamina propria and myometrium newborn fibroblasts, and damaged collagen fibers, elastic fibers, such as restructuring, so as to achieve vaginal wall thickening and tighteningof the vagina so that firmness, sensitivity enhancement, vagina tight as ever. Vaginal tightening laser does not produce skin burns due to high temperature, each capable of Homogeneous heat, acting on a few hundred nanometers thickness Mucosa organization. How does it work? The Co2 laser uses a unique head piece which tracks the CO2 10.6 um wavelength light as it passes light through its optical lens to penetrate the skin. We can control the depth of the penetration from only a few micrometers in depth (only as deep as a few sheets of paper) to much deeper with tiny thermal channels. This will also determine the length of healing, the number of treatments and the cost. Each thermal channel creates a small micro-injury but does not significantly disturb or disrupt the surrounding tissue. These microscopic injuries caused by the laser (around 15-20% of the treated area) are the beginning of the healing process. By creating thousands of these perforations underneath the skin, your epidermis layer starts to heal from the edge of these microscopic perforations very quickly. By healing so fast it remodels tightens and stimulates the collagen, your skin tightens which in turn smooth out lines, and significantly improves your skins tone and complexion.
