On average it takes in the region of 3 sessions before the Syringoma are gone. In the case of particularly thick Syringoma, it can take more sessions but usually, 3 sessions are more than enough to achieve satisfactory results. Therefore you have to be a little patient and repeat the treatment until you are happy with the results. On the other hand, you have a lot of SyrinRemover with you because we usually send you a lot more SyrinRemover than you need, just to make sure you will be completely satisfied with the results. Please note that some syringoma can recur and they tend to grow back very quickly (despite the method used to remove them, including laser and electrofulguration or electrodesiccation) Also you might want to use the SyrinRemover to manage the recurring Syringoma.
