Immediate firming effect can make loose skin feel the lifting and firming effect immediately after treatment. Long-term regeneration effect The long-term regeneration effect is that within two to six months after treatment, stimulated collagen in the dermis will gradually proliferate, thus promoting the dermis to restore firmness and elasticity, and wrinkles will gradually disappear from deep to shallow. Principle of electric wave lift and wrinkle removal: electric wave enters subcutaneous tissue at high frequency, which makes the natural resistance movement of subcutaneous tissue generate heat energy. When the temperature reaches the zero point of 68-72 degrees Celsius, collagen will contract immediately, and at the same time stimulate the dermis to secrete more new collagen to fill the gap between contracted and lost collagen, thus re-supporting the skin scaffold and restoring skin elasticity.
