Sunburn protection

Ultraviolet light can injure skin before a person notices heat or redness. A previous [Sunburn](/conditions/sunburn/) does not make the skin resistant to another one. Repeated exposure contributes to [Sun-Damaged Skin](/conditions/photoaging/), while recently burned or peeling skin is especially easy to irritate.

Plan outdoor time around shade where practical. Wear a wide-brimmed hat, sunglasses, closely woven clothing and footwear that covers exposed skin. Apply broad-spectrum sunscreen to uncovered areas before going outside, following the product label for amount and reapplication. Reapply after swimming, sweating or towelling, even when the product is water resistant. Protect ears, neck, scalp partings, hands and the tops of feet. Keep infants and young children in shade and clothing, and ask a clinician about suitable products for sensitive or recently injured skin.

Protection cannot replace assessment of a serious burn. Seek advice for extensive blistering, severe pain, spreading [Skin Redness](/symptoms/skin-redness/), fever, pus, dizziness, vomiting, confusion or difficulty drinking. Eye pain or vision changes after sun exposure need prompt attention. Do not apply sunscreen over open blisters without clinical guidance.

Ask which protective clothing and sunscreen suit your skin, whether a medicine increases sun sensitivity, and how long to wait before exposing peeling skin to outdoor light.
