Gooooodd afternoon to you lovely people! It is saturday around 230pm for me and i was sitting here thinking that i have not yet explained how to use the hyaluron pen for people considering purchasing it!. well here it goes! the hyaluron pen is a needle-free painless alternative to lip injections the NEEDLE way lol. the pen comes with ampoules and all you have to do is fill the ampoule with lip filler which is usually made from cross linked hyaluronic acid..then you screw it into the pen and you pull the lever back so that the spring is ready (also at this time you should have your pen turned all the way out so that you can see every line on the pen).. you must pull the lever back on the pen it first before you twist down a line or two (never more than 2 lines down on the pen) ..then you would next place the end of the ampoule up against the part of the lip you want to inject. when you press the button i should warn you it is a jumpy sound lol but it absolutely does not hurt at all!!! some people bruise after but i have not yet had that happen..there are tutorials online for which parts of the lip are safe to be injected and i advise you to go read and follow one of those before you start!! and ladies and gentlemen, it is as simple as that! i have been getting filler for years so when i discovered the hyaluron pen i was extremely excited. you dont have to book an appointment or leave your house or even spend hundreds of dollars anymore! there are fillers you can purchase on amazon and some other sites as well but i recommend amazon because it seems the safest lol. also last thing, you can also use the filler to inject on your face to fill lines etc, but i would also read up about that as well before doing so. there are places that you shouldnt inject such as around the eyes. this is all just my personal experience with the hyaluron pen, this is not medical advice or any other advice..i am not a professional. i am just here to share my experiences!! please read up and watch plenty of youtube videos before you decide if its right for you!!
