What should you know about cellular sunburn on shins?

Ultraviolet radiation injures skin cells and triggers inflammation. The shins can be especially uncomfortable because the skin may rub against clothing and the legs can swell after prolonged standing. Redness and heat may be followed by tightness, blisters or peeling as the damaged outer layer sheds. This pattern fits [Sunburn](/conditions/sunburn/), while repeated exposure contributes to [Sun-Damaged Skin](/conditions/photoaging/). Sunburn is not made safer by tanning, and peeling skin should not be pulled away.

Move out of direct sun, cool the area with a damp cloth or a comfortably cool shower, and drink fluids normally. Apply a bland moisturiser or [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/) to intact skin; avoid harsh scrubs, fragranced products and popping blisters. Wear loose clothing and protect the shins from further exposure. A clinician may consider [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for selected inflammatory symptoms, but do not apply prescription treatment without advice.

Get medical help for extensive blistering, severe pain, marked swelling, dizziness, vomiting, confusion, fainting or inability to keep fluids down. Seek prompt review if blisters become cloudy, drain pus, or the surrounding skin becomes increasingly red and hot. You can also read about [Skin Blisters](/symptoms/skin-blisters/), [Peeling Skin](/symptoms/skin-peeling/) and [Skin Redness](/symptoms/skin-redness/) when describing symptoms to a clinician.

Are the blisters superficial or infected? What dressing is suitable for the shins? Which pain-relief options fit my health history? When can I return to outdoor activity, and how should I protect this area afterward?
