The Hyaluron Pen operates by creating enough pressure externally against the tissue to “push” the hyaluronic acid filler into the dermal layer of your skin without the use of needles. Most commonly in cosmetic cases, it is being used for lip plumping. 

Hyaluron Pen lip filler treatments typically lasts 3-4 months. The results are a more natural look and the treatment can be done every 3-4 weeks to “build” fuller lips until you achieve the size and plumpness you want.
