The nano infusion process is done with a handheld device or "pen" that moves the nano cartridge up and down on the surface of the skin. This treatment helps create channels in the skin for better product absorption into not only the epidermis, but the dermis as well, feeding the skin the nutrients it needs. This treatment promotes anti-aging and toning and firming the skin. The gentle Nano treatment will deliver product deeper into the skin to help improve tone and texture.
