For about the past 4-6 weeks the skin on my face has completely changed. My cheeks are red, flaky and feel like they are burning. Also I've broken out in quite a lot of spots that I haven't had since teens ( I'm 42). I've switched to Aveeno skin care range but nothing has made a difference. Is this rosacea, and if so what's the best thing I can do to try and clear it up?
