What should you know about skin burn due to sun?

Sunburn may become more noticeable after leaving the sun, with warmth, stinging, tightness, redness, or later peeling. Blisters indicate more substantial skin injury and should not be deliberately opened. Burning that follows a new product may instead reflect Contact Dermatitis. Persistent facial flushing or sensitivity can overlap with Rosacea. One-sided burning followed by grouped blisters is not typical sunburn and can occur with Shingles, so the pattern and timing matter.

Move out of direct sun, cool the skin with a cool damp cloth or a cool shower, and drink fluids. Apply a plain moisturiser after cooling if it does not sting. Wear loose clothing and avoid peeling, scrubbing, or breaking blisters. Keep blistered skin clean and covered loosely with a non-stick dressing if clothing rubs. Do not return to direct exposure while the skin is healing; use shade, clothing, and a broad-spectrum sunscreen on intact skin afterward. Stop any product that causes extra burning.

Arrange prompt medical care for extensive blistering, severe pain, marked swelling, fever, vomiting, dizziness, confusion, faintness, or signs of dehydration. Urgent help is needed for breathing difficulty or swelling of the face. A child, older adult, or person with a significant medical condition may need earlier advice. Seek assessment if redness, warmth, pain, or drainage keeps worsening, as these can signal infection rather than routine peeling.

How deep or extensive does this sunburn appear? What can I safely apply if moisturiser stings? How should I cover blisters? Which symptoms mean I need urgent review, and when can I resume normal outdoor activity?
