Teosyal Ultra Deep has strong viscoelastic and cohesive qualities, making it ideal for adding volume to specific areas, resetting face lines, and filling deep creases in thicker skin. Teosyal Ultra Deep is the second strongest treatment in the Teosyal line; it is also one of the most dramatic and long-lasting, and it is specifically designed for use in high-volume treatments. It is also Teosyal's densest product, therefore it can produce spectacular results.
