Hyaluronic acid is differentiated according to its molecular size. We speak here of high-molecular and low-molecular hyaluronic acid.
It is logical that high-molecular hyaluronic acid penetrates the skin much more easily than low-molecular hyaluronic acid.
For this reason, hyaluronic acid for cosmetic purposes should either be comminuted or already fragmented.
Fragmented or crushed hyaluronic acid is referred to as hydrolyzed sodium hyaluronate in the ingredients list (INCI) of cosmetics.
This low-molecular hyaluronic acid should of course also be used for microneedling.
Sterility is an absolute must for a hyaluronic serum for microneedling applications!
Cosmetic literature often describes that a hyaluronic acid preparation should be applied after microneedling when the puncture channels are still open so that it can penetrate the skin through the puncture channels.
In this case too, it is essential that only sterile products are used, which are also applied to the skin in a sterile manner to reduce the risk of infection and inflammation.
To improve the results of microneedling treatments in combination with hyaluronic acid, the hyaluronic acid serum is often applied to the skin before microneedling and then injected directly into the skin using a dermapen or dermaroller.
In this case, the sterility of the serum used and a sterile working method are absolutely essential.
