I recently started having Rosacea on my face and forehead. The dermatologist tried everything in their arsenal but no joy. It did nothing. There is no cure, I am told, but I have found something that gives temporary clearing of the red skin. It is a micro-encapsulated peroxide exfoliant, normally used to treat acne.
I will not name a brand, but there are many with the micro-encapsulated peroxide.
It will peel the rosacea layer of skin off and last several weeks for me. YMMV.
Use at your own discretion.
I apply it several times a day and at night and it will itch for a day or two, then the dead skin can be washed off and the skin is then clear.
This is not medical advice, simply relating my experience with it.
I have no financial interest in any of these products, and everything is from my personal experience.
I hope this helps someone.
