Fractional RF Technology is useful for minimal invasive epidermal rejuvenation. Radio Frequency energy is emitted at the end of fractional RF micro-needle and allows effective treatment of the target area at a deeper dermis level without damaging the epidermis. Fractional RF stimulates collagen and elastin to improve wrinkle, scar, skin tightening and stretch marks. After the treatment, the skin feels tight and warm similar to a slight sunburn. Erythema and oedema may appear with deeper treatment levels.
