Bruise free injectables involve the use of the revolutionary Micro-cannula technique, in which a blunt-tip cannula (small cylindrical tube) is used instead of a traditional sharp hypodermic needle. This significantly reduces the likelihood of piercing a blood vessel during a facial filler injection, which means virtually no bruising and very minimal swelling in result. Micro-cannula injections are much safer and more comfortable for the patient and provide improved accuracy for the plastic surgeon. Dr. Stong is one of very few plastic surgeons in the country who use bruise free injectables almost exclusively when offering facial filler treatments.
