Understanding the Layers of Skin Affected by a 2nd Degree Burn


Burns can cause significant damage to the skin, and understanding the extent of the injury is crucial for proper treatment and management. A 2nd degree burn, also known as a partial-thickness burn, involves damage to specific layers of the skin. In this blog post, we will delve into the layers of skin affected by a 2nd degree burn, providing insights from MyCPR NOW to help you better comprehend the nature of this burn injury and its implications for treatment and healing.

1. The Structure of the Skin:
To understand the layers affected by a 2nd degree burn, it is essential to familiarize ourselves with the structure of the skin. The skin is composed of three primary layers:

a. Epidermis: The outermost layer of the skin, providing protection against the external environment and serving as a barrier against pathogens and moisture loss.

b. Dermis: The middle layer, responsible for providing strength, flexibility, and support to the skin. It houses blood vessels, nerve endings, hair follicles, and sweat glands.

c. Subcutaneous Tissue (Hypodermis): The deepest layer, composed of fat cells that provide insulation, cushioning, and energy storage for the body.

2. Understanding 2nd Degree Burns:
A 2nd degree burn is characterized by damage to both the epidermis and a portion of the dermis. These burns can vary in severity, ranging from superficial 2nd degree burns, which affect the upper layers of the dermis, to deep 2nd degree burns, which extend deeper into the dermis.

3. Superficial 2nd Degree Burn:
In a superficial 2nd degree burn, the burn injury affects the upper layers of the dermis, sparing the deeper portions. Characteristics of a superficial 2nd degree burn include:

a. Redness and Blanching: The affected area appears red and may blanch when pressed.

b. Blisters: Small, fluid-filled blisters may develop within the burn area.

c. Pain and Sensitivity: Superficial 2nd degree burns are typically painful and sensitive to touch.

d. Rapid Healing: These burns tend to heal within a few weeks without scarring, as the underlying dermis contains intact structures necessary for regeneration.

4. Deep 2nd Degree Burn:
A deep 2nd degree burn extends deeper into the dermis, affecting a larger portion of this skin layer. Characteristics of a deep 2nd degree burn include:

a. Red, Mottled Appearance: The burn area may exhibit a red or mottled appearance due to damage to blood vessels within the dermis.

b. Blisters and Wound Fluid: Similar to superficial 2nd degree burns, blisters may form. However, the blisters in deep 2nd degree burns tend to be larger and may break open, resulting in wound fluid.

c. Sensitivity and Pain: Deep 2nd degree burns are typically painful and sensitive to touch.

d. Slower Healing and Scarring: The healing process for deep 2nd degree burns is longer and may require specialized care. Scarring is common, as these burns involve damage to important dermal structures.

5. Treatment and Management of 2nd Degree Burns:
The treatment approach for 2nd degree burns depends on the severity and extent of the injury. However, general principles include:

a. Cool Water or Cold Compress: Applying cool water or a cold compress to the burn area can help alleviate pain and minimize further tissue damage.

b. Protecting the Burn: Covering the burn with a clean, non-stick dressing can protect it from infection and promote a moist healing environment.

c. Pain Management: Over-the-counter pain relievers or prescribed medications may be used to manage pain associated with 2nd degree burns.

d. Medical Evaluation: Deep 2nd degree burns may require medical evaluation and specialized treatment, such as debridement, skin grafting, or the use of advanced wound care products.

e. Rehabilitation and Scar Management: Once the burn has healed, rehabilitation exercises and scar management techniques, such as massage or silicone gel application, may be beneficial.


A 2nd degree burn, or partial-thickness burn, involves damage to both the epidermis and a portion of the dermis. Superficial 2nd degree burns affect the upper layers of the dermis, while deep 2nd degree burns extend deeper into the dermis. Understanding the layers of skin affected by a 2nd degree burn is crucial for appropriate treatment and management. By recognizing the characteristics of superficial and deep 2nd degree burns, you can better assess the severity of the injury and make informed decisions regarding wound care, pain management, and rehabilitation. Remember, seeking medical evaluation and guidance is essential for the proper management of 2nd degree burns, particularly deep burns that may require specialized treatment.
