Hyaluron Pen is an innovative device that uses extremely effective technology by method of pressure technology which allows enough pressure to launch hyaluronic acid mixture into the skin without the use of an invasive needle. The process takes about 30-45 mins and is virtually painless with little to no downtime (as each individual heals differently). The results are a more natural look and the treatment can be done every 3-4 weeks to “build” fuller lips or perfect face until you achieve the size and plumpness you want for your lips and smoothness for your face.
