"Its fine, they always use a new needle"
Many people believe that as long as a tattooist or permanent makeup technician uses a new, sterile needle for their treatment, that the procedure must be safe. Unfortunately, this is not always the case.
Many of the needles on the market, particularly the cheaply-made Chinese versions, can be lacking the protective membranes in the cartridge that are imperative for preventing the backwash of bodily fluids into the handpiece itself. Therefore, new needle or not, the hand piece that is used client after client could actually then be carrying blood-borne viruses from person to person - scary stuff!
At Micro Art LDN, only the highest quality European needles are used. The Biotek needle cartridges are CE Class and contain internal diaphragms to prevent body fluids and airborne contaminants entering the handpiece, protecting against cross-infection.
