Hi dear thats true u r suffering from rosaceae. This is a heat sensitive condition where blood vessels get dialated on exposure to heat. And hence ur face become red. Ipl is the treatment of choice for this which u have already taken. Here are my suggestions.
Avoid tea coffee and other hot beverages.
Avoid exposure to sun as far as possible,
use a sunscreen with spf more than 50. This u should apply 3 times a day. Use metrogyl
gel in night. Thank u
