I think we are all different and what helps one person will cause a flare up for someone else. For me I always tend to hone in on products for sensitive skin especially with my cleansers. There is a brand called Savi that have some lovely gentle cleansers but sadly they are not cheap. I was lucky enough to grab several of their products as they were getting ready for new packaging and everything in the old packaging was heavily discounted. Also Dr Lewinns gentle polishing gel is awesome and a super gentle scrub that I use in the shower. Oh and speaking of the shower….dont have the water too hot even in Winter as this is something I found would flare my Rosacea instantly.
Moisturisers from brands like Cetaphil or dermaveen are great. My skin also loves Olay and Palmers moisturisers, The Palmers one is interesting as its quite heavily scented and you would think my skin would freak out but its very happy with it.
Sunscreen I love the Neutrogena Dry Touch. Sunscreens that are overly oily freak my skin out and burn.
Good luck with it. Its the bane of my life.
