A few months back, I got badly sunburnt even though I was wearing sunscreen. After roughly three months, today way the first time I was able to enjoy some sun again. Now the weird thing is, after a few minutes the skin on my arms started to tan but there's still loads of white spots inbetween and it generally looks uneven. I can only imagine this somehow relates to my previous sunburn, as it looked like that after the skin peeled off. Can anyone tell me if this is something I should get checked out? And is there anything I can do to stop this, as the uneven tan looks rather awkward.
