Hi...as a fellow sufferer, who has worked in operations for too many years really. Work has resulted (fortunately) in lots of flying. Alas the dry air in the cabin plays havoc with my skin, making it very dry and uncomfortable.
I really wish you all the very best but just be aware those very early starts, late finnishes, lack of sleep, struggle to eat the foods you know you really should will have a huge effect on your skin. If you are using cyclo it must be pretty bad.....
If I was you and if you have not tried it before, have a go out diary free, wheat free and alcohol free, sleep loads and stay stress free!
As I say I really wish you the very best of luck, but if you are thinking about spending vast sums on training I would consider what is really involved in a flying career, since it is not Psoriais friendly.
I find it hard enough getting through everyday working in ops !
Feel free to PM me if I can help in anyway.
