This minimally invasive treatment improves skin texture, softens wrinkles and smoothens scars. By using a device called the Dermapen 4 Medical Grade Skin Needling , oscillating micro-needles gently pierce the skin to stimulate the production of collagen and elastins. As the micro-needles pierce the skin and reach the platelets in your blood, growth factors are released that rejuvenate your skin and restore a more youthful appearance. This regenerative procedure stimulates the body’s natural wound healing response without scarring.
