Vitamin D Note
While sun protection is important, your body needs some UV exposure for vitamin D production. Most people get sufficient vitamin D with brief, incidental sun exposure. Consider a supplement if you have limited outdoor time.
Always reapply sunscreen every 2 hours and after swimming or sweating, regardless of SPF. No sunscreen blocks 100% of UV rays. Seek shade during peak hours (10 AM – 4 PM).
