Should I put a plaster over burns to make sure it doesn't get infected?

Condition analysis:
No. Don’t use any adhesive bandages as they’ll stick to the skin and may cause further damage. After cooling, cover the burn with cling film or a clean plastic bag – this will help prevent infection.

Instructions:
Coconut oil: Coconut oil is an excellent source of skin-healing vitamin E and it also contains fatty acids that are anti-fungal and anti-bacterial, which help keep your burn from becoming infected. If a scald has left a nasty mark on your skin, one home remedy suggests adding lemon juice to the coconut oil before massaging it into the mark. The acidic properties of lemon juice will help lighten the scar while the coconut oil helps it heal.

2. Lavender oil: A French chemist discovered the healing power of lavender oil in the early 1900s. When he severely burned his hand in a lab accident and plunged it into a vat of lavender essential oil, the oil eased the pain and his burn healed quickly. Mix 1 teaspoon of pure lavender essential oil into about 2 ounces of water in a misting bottle. Shake and mist burned skin lightly as often as needed. Tea tree oil and witch hazel are also effective remedies for a minor burn.
