Peeling skin on the back after sunburn

The back may be hard to reach, so ask someone you trust to check for extensive blistering, increasing swelling, drainage, or colour change. Peeling does not erase the effects of ultraviolet exposure.

Ultraviolet radiation injures cells in the outer skin. As the body clears those damaged cells, dry sheets or flakes lift away and reveal sensitive new skin underneath.

Redness, warmth, soreness, and later peeling fit a typical sunburn pattern. Large blisters, severe swelling, pus, or worsening pain are more concerning than simple flaking and need closer attention.

Move out of the sun, cool the area with a gentle shower or damp cloth, and pat rather than rub. Apply a plain fragrance-free moisturiser while the skin is slightly damp, and drink fluids regularly.

Do not pull away attached skin or burst blisters. Wear loose, soft clothing and keep the back covered from further sunlight. Avoid harsh scrubs, fragranced products, and topical numbing products that can irritate damaged skin.

Get prompt medical advice for extensive blistering, severe pain, worsening swelling, signs of infection, or a burn covering a large part of the back. Extra caution is appropriate for babies, young children, and people who are medically vulnerable.

Seek urgent care if sunburn is accompanied by confusion, fainting, marked weakness, repeated vomiting, severe headache, breathing difficulty, or inability to keep fluids down. These are whole-body warning signs, not routine peeling.

Ask how to dress any open blister, which moisturiser suits your skin, and whether a medicine you take increases sun sensitivity. After healing, discuss practical shade, clothing, and sunscreen habits for protecting the back.
