Try taking a cool shower or bath or placing wet, cold wash rags on the burn.
Avoid products that contain benzocaine, lidocaine, or petroleum (like Vaseline).
If blisters are present, dry bandages may help prevent infection.
If your skin is not blistering, moisturizing cream may be applied to relieve discomfort.

Aspirin, acetaminophen and ibuprofen can help combat pain
Anesthetic creams or sprays containing benzocain and lidocain provide temporary relief
Antibacterial and antimicrobial soaps and antiseptics help prevent infection
Aloe-based products soothe and cool overheated skin
Moisturizers can help keep your skin from drying out and tightening up

DO NOT apply petroleum jelly, benzocaine, lidocaine, or butter to the sunburn. They make the symptoms worse and can prevent healing.
DO NOT wash burned skin with harsh soap.
