How do I choose a good sunscreen?

Select a broad spectrum sunscreen that covers both UV-A and UV-B rays with a sun-protection factor (SPF) of at least 15. Make sure to read the list of ingredients to check for any dyes, fragrances or components (such as PABA) that you may be sensitive to. Choose a waterproof/sweat-proof product if swimming or exercising and an oil-free formulation for the face if prone to acne.
