Sunburn

Manage sunburn by identifying blistering or systemic illness that warrants urgent assessment, avoiding further ultraviolet exposure, and using layered photoprotection to prevent recurrent injury. Broad-spectrum sunscreen, protective clothing, and sun avoidance reduce ultraviolet-associated skin damage.

Clinical question: How should clinicians triage acute sunburn and prevent recurrent ultraviolet injury?

Initial assessment

Triage acute sunburn for severe injury and alternative diagnoses

Classify the presentation before treating it as routine uncomplicated sunburn.

Document exposure timing, anatomic distribution, blistering, skin pain, peeling, ocular symptoms, and systemic complaints. Acute phototoxic eruptions can begin hours to days after ultraviolet exposure and may range from sunburn-like erythema and peeling to severe blistering in exposed sites. WileySpotlight commentary: Navigating the cutaneous side effects of ... A sharply photodistributed or unexpectedly severe reaction should trigger a medication and topical-product review rather than attribution to exposure duration alone.

Escalate same-day assessment for extensive blistering, uncontrolled pain, systemic illness, or concern for a serious cutaneous adverse reaction. Sunburn severe enough for burn-service admission is uncommon, whereas most cases are self-managed with simple creams and analgesics; this contrast supports escalation when injury exceeds the usual limited erythematous presentation.

Medication safety

Identify treatments that amplify ultraviolet injury

A medication review is most useful when severity or recurrence is discordant with reported exposure.

Topical retinoid counseling should include sun-exposure precautions at initiation and during dose escalation. Tretinoin labeling identifies skin irritation and photosensitivity with sunburn risk; adapalene labeling warns about ultraviolet and environmental exposure; and tazarotene labeling identifies photosensitivity and sunburn risk. accessdata fda[PDF] Risk Assessment and Risk Mitigation Review(s) - accessdata.fda.gov In a patient with retinoid dermatitis plus sunburn-like erythema, distinguish additive irritant dermatitis from a predominantly photo-induced reaction because both require reducing ultraviolet exposure.

Do not reflexively label every sun-exposed eruption as simple sunburn. Severe blistering after ultraviolet exposure can occur in cutaneous drug reactions, and a recurrent pattern despite protective behavior should prompt reassessment of prescribed, over-the-counter, and topical agents.

Prevention

Prescribe layered photoprotection rather than sunscreen alone

Select a product with labeled broad-spectrum protection, then pair it with exposure reduction.

Recommend a broad-spectrum sunscreen with SPF 15 or higher, including on cloudy days. FDA states that broad-spectrum products protect against UVA and UVB radiation and that only broad-spectrum sunscreen with SPF at least 15 protects against ultraviolet rays associated with skin-cancer risk and early skin aging. fdaTips to Stay Safe in the Sun: From Sunscreen to Sunglasses - FDAfdaSunscreen: How to Help Protect Your Skin from the Sun SPF is derived from a sunburn test and primarily reflects UVB protection; it should not be interpreted as a complete measure of UVA protection unless the product is labeled broad spectrum. fdaSunscreen: How to Help Protect Your Skin from the Sun

Counsel that sunscreen is adjunctive, not permission to extend exposure. FDA recommends reducing ultraviolet injury with a combination of sunscreen and other protective measures, and ultraviolet exposure occurs year-round. fdaTips to Stay Safe in the Sun: From Sunscreen to Sunglasses - FDA Protective clothing and avoidance of midday or peak exposure are practical complements to sunscreen use.

How to explain SPF without overstating it

SPF compares the ultraviolet exposure needed to produce sunburn with versus without the product, so it measures sunburn protection rather than all clinically relevant radiation exposure. fdaSunscreen: How to Help Protect Your Skin from the Sun Use the broad-spectrum designation to address UVA and UVB coverage, and pair sunscreen with behavioral and clothing-based protection. fdaTips to Stay Safe in the Sun: From Sunscreen to Sunglasses - FDAfdaSunscreen: How to Help Protect Your Skin from the Sun

Follow-up

Reassess recurrent or atypical sunburn patterns

Recurrent injury should lead to prevention review and diagnostic reconsideration.

At follow-up after a significant episode, document the exposure setting, medications, photoprotective behavior, and whether erythema or blistering was confined to exposed skin. A mismatch between modest exposure and severe reaction should redirect the evaluation toward photosensitivity or medication-associated phototoxicity. accessdata fda[PDF] Risk Assessment and Risk Mitigation Review(s) - accessdata.fda.govaccessdata fda[PDF] This label may not be the latest approved by FDA.

For patients receiving phototherapy for atopic dermatitis, recognize that treatment is distinct from incidental sun exposure but has relevant ultraviolet adverse effects. FDA review materials describe phototherapy as an option with a time-intensive in-office schedule and risks that may include actinic damage, sunburn-like reactions, skin cancer, and cataracts depending on modality. accessdata fda[PDF] 761055Orig1s000 | FDA New sunburn-like reactions during phototherapy warrant review of the modality, cumulative exposure context, and concurrent photosensitizing treatments.

Use every sunburn encounter to identify preventable future exposure, particularly in patients with repeated burns, retinoid use, or evidence of chronic ultraviolet injury. Regular and proper sunscreen application has been reported to reduce sunburn, photoaging, and later skin-cancer risk, but sunscreen should remain part of a broader exposure-reduction strategy.
