Sunscreen in Antarctica: Actually Crucial—Despite Ozone

Correction: Wearing sunscreen in Antarctica IS crucial. The original answer was dangerously wrong.

Why UV Risk Is Extreme

• Ozone hole: Seasonal (spring) depletion over Antarctica lets through intense UV-B. Even outside the hole, ozone is thinner at high latitudes.
• Reflection: Snow/ice reflects **80–90% of UV**—you get hit from above AND below. Effective UV dose doubles.
• High elevation: Much of Antarctica is 2,000–3,000m+; UV increases ~10% per 1,000m.
• 24-hour summer sun: Continuous exposure during field season.
• Low sun angle ≠ low UV: At high latitudes, UV-B is reduced but not eliminated; reflection compensates.

Consequences

• Severe sunburn in minutes (especially nose, lips, ears, under chin).
• Photokeratitis ("snow blindness")—corneal burn, excruciating, temporary blindness.
• Long-term: skin cancer, cataracts, premature aging.

Required Protection

• Broad-spectrum SPF 50+ sunscreen (lip balm too), reapplied frequently.
• UV-blocking sunglasses/goggles (category 4, wrap-around).
• Face mask/balaclava, wide-brim hat, neck flap.
• Full skin coverage (lightweight UPF clothing).

All Antarctic programs (USAP, BAS, AAD, etc.) mandate rigorous UV protection. Ignoring it risks serious injury and mission failure.
