This lip plump service is proven safe and effective for adding volume and definition to lips and filling smile lines. Hydroporation uses pressure to push the liquid through the skin into the upper dermis. The Hyaluron Pen has just enough pressure for treating these delicate facial features. Needless fillers are more comfortable, cause less swelling, and provide a natural fullness to the lips. No needle fillers are safe and effective for reaching your lip goals.
