I have skin burns can i wet it when i take my shower? will petroleum jelly help? should i cover it or let it air dry?

Burn Types: Depends on the type of skin burn: First degree burns are red, painful and dry but no blisters. No ointment. Apply a hydrocolloid pad for pain relief. Second degree burns are red, swollen and blistered. Do not pop the blister. Apply antibiotic ointment and cover with a soft non-stick gauze pad. Third Degree burns appear white, charred and painless since the nerves are destroyed. See a DR for these.
