3 months post-injection I had a terrible allergic reaction to Teosyal Kiss that landed me in hospital. Their best guess was that I was having a reaction to the cross linking agent BDDE. Months later I went to a highly renowned plastic surgeon who recommended, and injected, Teoysal Global. I have been using Global for about 2 years now, reaction free. I want to change products because it doesn't last longer than 2 months in my body but I am worried I will react. What can I do? Is there a test?
