[|AI|]  HI, Welcome to Chat Doctor. Based on the description given, you might b suffering from Solar Urticaria. It is a type of physical Urticaria occurs commonly due to exposure to UV rays and sometimes even visible sunlight (Photoallergens). UV radiation can be present in all kinds of weathers. It depends on the area where you reside. If you are living in an area with less ozone layer covering or an area of high altitude, then the chances of UV radiation is high. Apart from the environmental factors some people have skin sensitive to UV rays.  The rash develops with in a matter of minutes and would disappear once you are indoor (it might take 10 mins too few hrs). Rash is commonly seen on exposed parts that is why you are experiencing rashes on face and neck. There are various modalities of treatments like antihistamines, desensitization, immune suppression etc., Please see a dermatologist and take his advice on the type of treatment that suits you. Wish you a healthy life Take care
