Why does sunburn cause peeling skin?

Peeling Skin is a very common presentation of Sunburn. Damaged cells lose their normal attachment and gradually flake away, often after redness, warmth, tightness, or tenderness. Peeling can be uneven, with larger sheets in some areas and fine flakes in others. The new skin underneath may look pink, feel sensitive, or show a temporary change in colour. Peeling skin can also have causes unrelated to sun exposure, including eczema, irritation, or infection, so persistent or recurrent peeling deserves assessment.

Moisturise gently and often with a fragrance-free product, especially after bathing. Use lukewarm water, mild cleanser, and soft towels. Let loose skin come away on its own rather than pulling or scrubbing it, which can cause raw areas and irritation. Protect the newly exposed skin from sunlight with clothing, shade, and broad-spectrum sunscreen used as directed. Avoid tanning and fragranced exfoliants until sensitivity has settled.

Contact a clinician if peeling is widespread, painful, oozing, associated with blisters or fever, or accompanied by marked swelling. Seek prompt help for confusion, faintness, severe weakness, repeated vomiting, or difficulty keeping fluids down after sun exposure. Arrange a dermatology review when peeling continues despite gentle care or keeps returning without a clear trigger.

Is this peeling consistent with sunburn? Which moisturiser is suitable for my skin? When can I resume active skincare? What signs would suggest infection or another skin condition?
