How do you stop the peeling skin from sunburn?

Unavoidable. Once sunburned, damage has already happened, and peeling is unavoidable. Treatment is aimed at reducing the symptoms of pain, typically with oral Ibuprofen and moisturize a lot.
Sunburn. Moisten with an apple cider vinegar bath. This is one of the most effective ways in which to prevent peeling. Purchase a good apple cider vinegar bath at your local health food store. Mix it in with your bath, lie back and let the healing begin. The vinegar helps to restore a healthy pH balance to your skin, which is an important component in the healing process.
