I had sunburn on the tip of my ears it became crusty and pealed now there are small brown spots that are not noticeable unless you look at closely ?

Normal skin response: Our skin tries to protect us from the damaging rays of the sun. If your skin on the ears peeled, that means you actually got a deep 1st-mild 2nd degree burn! Your skin didn't like that, so it is making more coloring (pigment from mole cells) to protect the deeper layers of skin from further damage. This frecking is often permanent and is a signal from your body to use sunscreen!!! Take care!
