Botox worked for 2 years (with approx. 6 months intervals). Then it stopped working. Over a period of 3 years, I've been to 4 different doctors for botox with double the amount of units. 2 of them tried Dyssport. No results. My forehead muscles feels constantly contracted, resulting in a headache at the end of the day. Please let me have advise, since I'm desperate not to have a tired forehead anymore. Apparently type B is unavailable to South Africa?
