My forehead feels bruised. A couple of years ago, I was traveling to San Francisco in a convertible with my daughter. I asked if she had any sunscreen and she gave me a lotion, assuring me it was in fact sunscreen... well it wasn't! I forehead got pretty burned and ever since then, even though no visible signs of the burning are present, my forehead feels bruised. This has been a good few years. Can anyone explain this?

Well lotin doesn't have spf in it so you got burned I can't explain the other part so sorry
