Hi from samw

Hi and welcome Sam, get yourself a good dermatologist and don't rely on the GP, try a good coconut oil as a moisturiser because it's really good one and not to expensive. Most treatments , in fact all treatments , will only work for a limited period of time it's just some are better than others and of course what works for one does not necessarily work for someone else . UV lights are, in my humble opinion, not to be used without supervision as my niece used one and ended up with skin cancer , I had quite a few sessions and they stopped me from using it anymore.
Have a good read on the site and ask any questions you want and you will find that the answers will be honest from people who have the same problem , when you see your derm next time go armed with list of different treatments and see which ones that they recommend then have another look on here to see which you think will suit you.
All the best, look after yourself Dave
