One of the key concerns of patients undergoing facial injectable cosmetic treatments is bruising. Bruises can be embarrassing and often are difficult to conceal.
Bruises are caused during injectable treatments by disrupting a vein under the skin. Facial veins are not usually visible to the naked eye, especially in those with darker skin types.
The Accuvein is able to visualise veins beneath the skin. This allows the practitioner to make adjustments to their injection points to avoid these veins and therefore reduce the risk of bruising.
How does Accuvein work?
Haemoglobin in the blood and veins absorbs infrared light emitted by the Accuvein device. The Accuvein then projects an image of the veins back on to the skin. This allows the injector to visualise the location of the veins and avoid them.
Blunt tip cannula and Accuvein – a perfect partnership
Blunt tip cannulae can be used to inject dermal fillers. They tend to be slightly longer than needles, and their tip, unlike needles are rounded. An entry point in the skin is made with a needle. The cannula is then passed through this entry point and then gently directed to the areas to be injected with dermal filler. Because the tip is rounded or blunt, it is significantly less likely to perforate a vein and cause bruising. It simply pushes the vein aside, as opposed to a needle which would pass directly into or through the vein.
In combination with the Accuvein, blunt tip cannula can be used to avoid veins. The Accuvein visualises the locations of facial veins, and the blunt tip cannula can help to prevent perforation of veins as fillers are injected.
