JUVGEN is a self-dermal regeneration procedure that alternately injects carbon dioxide gas and hyaluronic acid into the dermal layer. The CO2 gas injected first provides a temporary stimulus to the tissue, increasing blood flow and activating fibroblasts, while the subsequently injected hyaluronic acid fills in moisture and volume. As this stimulus is repeated, the production of autologous collagen and elastin is induced, gradually filling in depressed scars and wrinkle areas.
