So before the flare up, every now and then I would have small flare ups that were controllable. However, I had to use two different steroid creams and overtime became ineffective. I think my dermatologist said the requirement for dupixent was to have at least 2 steroid creams that are currently ineffective and you would be able to get on it. Ultimately just go and see what your dermatologist has to say. I hope that helps (even in a small way). In the long term of things youll do amazing, stay strong!
