In the Spring of 2014 I had dysport injections into my upper lip to address vertical lines. I had never treated this area before nor used Dysport. Now I have almost permanent flaking and redness of the skin on my upper lip. I have tried topical treatments and experimented with dietary changes - eliminating dairy, wheat and caffeine - to no effect. Its unsightly, itchy and irritating and I can't wear foundation or lipstick. Could this be a side effect of Dysport and is there an antidote?
