Blood thinners make you bleed. If you’ve had Botox and fillers in the past, then you’ll know there’s always some bleeding involved with the treatments. If that bleeding doesn’t stop, then the amount of bruising can become significantly worse. it’s not absolutely contraindicated and eventually it’s up to each individual provider and yourself if you’re willing to put up with a potential increased bruising risk of having these treatments. There are certain techniques that can be used to minimize bleeding and bruising from treatments requiring facial injections. One of them is using vasoconstrictive drugs before the treatment. If a provider uses topical local anesthesia with vasoconstrictive drugs in it, the skin will with time blanch from constriction of blood vessels temporarily while doing the injection. The vasoconstricting drugs create the temporary blanching effect by shutting down the blood flow in the skin treated with topical local anesthetic containing vasoconstriction drugs. For example, before I do lip fillers, I typically pre-inject the lip with lidocaine and an increased concentration of epinephrine. I can use very small amounts of local anesthesia and get an excellent vasoconstrictive effect in the lip, making patients virtually have zero bleeding and minimizing the chance of bruising.. This also serves the patient and myself and that the patient has no pain or discomfort during the lip injection. Pre-injecting the lips with lidocaine with epinephrine can be mildly uncomfortable, but typically not nearly as painful as having filler without local anesthesia. In the end, each provider will have their own decision to make. I suggest you update all providers regarding any changes in medication’s. You take. Best, Mats hagstrom, MD.
