I would go to the doctor and get some steriod cream for a start. Then just use plain luke warm water to cleanse your face. As for moisturiser try LUSH Dream Cream/Lotion, it is just oat milk which is very very gentle. Infact I think its for your body but you can use on your face. If you go into a LUSH store they will give a sample in a little pot for you to try.
No matter what brand you should do a patch test 24 hours before using. Some of the vendors on QVC did used to say that.
Lots of people complaining about Liz Earle upsetting their skin, even people who used to use it without problem. Any brand no matter who can have a reaction with someone. I know I cannot use anything with rose in it, yet they say rose is the thing for mature/dry/sensitive skin.
Once your skin has settled down, just go back and use whatever it was you used before as it seemed to work for you.
Honestly its too expensive to keep ordering from QVC to have to send back. You need to find which ingredient is causing this, trial and error. There is natural AHAs in the Melting Cleanser which is seems a smaller amount than in the Papya Mask. That one I cannot use as it makes me itch, I only used once and did not repeat. So each brand if you can get samples try behind your ear for 24 hours and it anything itching, tightness etc do not use on your face and disguard.
I have mild roseaca and Elemis agrees with my skin. BUT, I would not even think of trying the Tri range, as I said Papaya Mask which is suppose to be gentle makes me itch(not tingle but itch), the Eye Mask because of the rose makes my under eye sore and red.
