What's the difference between first-degree and second-degree burns?

April 5, 2026

Quick Answer

First-degree burns affect only the outermost layer of skin, causing pain, redness, and swelling, while second-degree burns penetrate deeper into the skin, causing blisters, charring, and a white or yellowish appearance. The primary difference lies in the depth of tissue damage.

Identifying and Treating First-Degree Burns

First-degree burns are relatively easy to identify, as they cause pain, redness, and swelling. They do not blister, and the affected skin remains intact. To treat first-degree burns, rinse the area with cool tap water for 10-15 minutes to reduce pain and promote healing. Apply a topical antibiotic ointment, such as Neosporin or Bacitracin, to prevent infection. Cover the area with a non-stick dressing or bandage to protect the wound. Monitor the burn for signs of infection, such as increased redness, swelling, or pus. Keep the burn moist with a topical ointment or cream to promote healing.

Treating Second-Degree Burns

Second-degree burns require more aggressive treatment. Rinse the affected area with cool tap water for 15-20 minutes, then gently clean the area with mild soap and water. Apply an antibiotic ointment and cover the area with a non-stick dressing or bandage. Monitor the burn for signs of infection and seek medical attention if the burn blisters or forms a scab. For more severe second-degree burns, seek medical attention immediately. In some cases, a healthcare professional may need to surgically debride the wound to remove dead tissue and promote healing.
