What it is
A sunburn is when the skin becomes red and painful from staying in the sun too long. Blisters may appear.
What you can do at home
What to do
- Apply a cold cloth to your child’s skin or give them a cool bath for 10 to 20 minutes.
- Apply an unscented moisturizing cream or aloe vera gel.
- Have your child drink plenty of liquids (such as water, rehydration drinks, milk).
- If your child is in pain, follow your pharmacy’s advice. You can give them acetaminophen (Tylenol) or ibuprofen (such as Advil) if there are no contraindications. Note: Ibuprofen should not be given to children under 6 months of age.
If the skin or blister is broken or torn:
- Apply an antibiotic ointment (such as Polysporin) if there are no contraindications. Ask for advice at the pharmacy if needed.
- Apply a bandage and change it once a day and when it gets dirty. Gently wash the wound with tap water and mild soap before applying a new bandage.
Avoid
- Do not go back into the sun until the skin has healed. Do not apply sunscreen to a child under 6 months of age.
- Do not apply petroleum-based ointments or products, cortisone, or pain-relief cream. Ask for advice at the pharmacy.
- Do not pop the blister.
