Injectable treatments, including tear trough procedures, may result in side effects like bruising, swelling, slight redness, tenderness, and itching around the area of injection. At DRKS in Chiswick, we employ a cannula, a slender and pliable instrument, for the application of tear trough filler, which reduces the likelihood of bruising and swelling. Should any bruising occur, it can be discreetly covered with make-up the following day.
