Belotero is a hyaluronic acid(HA) injectable filler. Although I don’t use this filler on my patients, it’s fairly popular and appears to be a reasonable option. Like other HA fillers, it can be dissolved away by injections of hyaluronidase. Make sure to ask your doctor about using a cannula for optimal safety. It’s often used on label for the nasolabial folds, and off label for plumping up the lips and filling in the tear troughs.
