Hy , when I go out on a normal day ( UV rating 5) with a hat on and suncream lotion on my face ,outside for 30 minutes - I still get sunburned in my face- Does this mean I suffer from Photosensitivity ?? I have had 1-bcc removed already. Should I ask my GP for Melanin injections or will he refuse ? Can Melanin deficiency be tested for ???
