You get to get to the doctor, there is a gel on prescription which does help. Now it takes awhile to work. But I still will have a major upset now and then because of the sun, you really need to wear a sun screen all year. Sometimes I am lazy and don't apply. About two weeks ago I suddenly had a major breakout of the acne like spots and red rash and I am convinced it was the sun. Elemis do a Daily Redness Relief which is brilliant. It costs £49 but I go to ebay and got my last one for £17.10. I use Elemis Sensitive Facial Wash. But eveyone can be different what suits their skin.
