I have sunburn on my left shoulder and top of my back, it has started peeling and it is really sore the skin is now rough and it is really red.

Is there. a question here????

Ask again ,,be more specific (BTW there are many Over the Counter post sunburn creams etc but the basic thing they all do is sooth and protect skin from further damage and VASELINE is as good as any of them!! My Opinion Only...Hope it helps!
