Regardless of how experienced and good we are as aesthetic injectors, we have come to discover through the years of using the Hyaluron pen, that product seepage is something that simply can’t be avoided. Yes it helps to cut down on seepage when injecting 0.01-0.02 at a time, yes it helps to cock the pen first and then twist the chamber, yes it helps to use very firm pressure when injecting and yes it helps to keep your finger over the ampoule head at all times, but even after practicing all those preventative measures, product will still seep out the sides when injecting or spray out of the ampoule head when twisting or pulling away from the skin. Some professionals go as far as heating the lips first using steam or a hot cloth and some exfoliate first using a tooth brush or lip scrub. The simple truth of the matter is that pushing a product through the skin that is designed to expand and enhance fullness without the use of a needle is a remarkable yet daunting task.
When seepage happens it causes concern that nothing is making its way into the skin. We can be rest assured through thousands upon thousands of Hyaluron pen case studies that product is penetrating the skin tissue.
We can also be assured that patients will see results, but it might take time and more sessions to see results similar to that of needle injections. Typically results are seen after two to three sessions and 2ml-4ml of product using the Hyaluron pen. It’s defiantly a slower process and this is a very important fact to convey to your patients .
Over the years many Hyaluronic acid filler manufacturers have experimented with all types of HA densities to see if injecting a much thinner product would prevent product seepage, but even when practitioners themselves have experimented with thinned down filler ( using injectable saline 0.9% benzyl alcohol ) there was still product seepage. If the product was thinned down to much the cross-linking and results were compromised.
This is why injectors all over the world have come to accept that regardless of what type of Hyaluron pen you use and what type of product you use product seepage simply can’t be avoided.
