Going on holiday with RA


Hi, I am soon going to the US and I suffer with rheumatoid arthritis and autoimmune condition. Last holiday I went on was before my diagnosis and I experienced at the time, what I thought was just heat rash - it wasn’t it was an autoimmune linked skin flare up combined with my RA. I was wondering if anyone knew of any good brand of sunscreen/ protection that works for people with autoimmune conditions as last time it stopped me going outside completely. Thanks
