What should I do if my skin has been sunburned and turned red?

Avoid further sun exposure and seek shade to rest as soon as possible. Gently apply cool, wet towels or use a spray mist on sunburned skin to help lower skin temperature. For mild sunburn, placing chilled green tea bags, cucumber slices, or cold compresses gently on the affected areas may help constrict blood vessels and reduce redness, swelling, and pain. Temporarily avoid using skincare products or cosmetics containing alcohol, fragrances, or other irritating ingredients to prevent worsening skin irritation. When going outdoors, apply sunscreen, wear a hat, and use long-sleeved clothing for protection. If sunburn is severe, seek medical attention promptly, as topical medications or other treatments may be necessary.
