Dermetics uses the AlexTriVantage® – a unique laser that safely targets black and coloured tattoos without damaging surrounding skin. A local anaesthetic is used so patients experience little or no discomfort. Once treated tattoos will form a thin crust which sloughs off over several weeks. Treated tattoos must be kept covered and protected from any sun exposure while healing. Treatments are scheduled 6 to 8 weeks apart, and patients generally require 8 to 10 treatments, depending on each tattoo’s size, age, location and type of ink.
