Crystallite Depth 8 is a minimally invasive fractional treatment combining microneedles and RF energy.Under the control of the electronic system, dozens of insulated needles quickly penetrate the epidermis at the same time, emit RF energy from the needle tip, and then quickly exit the skin. RF energy is penetrated deep into the skin through tiny needles, causing tiny damage, penetrating and opening the absorption channel of the skin, so that nutritional products can enter the skin, and trigger the body's natural healing response. At this time, the thermal stimulation generated by RF together stimulates the self-repair mechanism of the skin, while liquefying and destroying fat cells, it shrinks a large area of soft tissue and stimulates the production of skin fibrous tissue and collagen, thereby reducing fat, remodeling and Tighten and lift the skin.
