    • Rapid and direct access to dermatology and dermatologic surgery


  • Sun avoidance
  • Avoid sunlight from 10am to 3pm
  • Sunblock (read more, link to Sunblock in General Guide)

  • Apply at least once daily, more frequently with perspiration or water exposure
  • Lipbalm with sunblock
  • UV protective clothing (read more)

  • Tanning beds expressly prohibited

Sunblock Recommendations:

  • SPF >/= 30 with broad UVA/UVB protection.
  • Types of sunblock
    • Chemical blockers: absorb the energy of UV radiation
      • Most only block a narrow range, must use combinations of chemical blockers to provide broad spectrum coverage
      • Parsol 1789 (avobenzone)-best UVA coverage
      • Mexoryl broadest coverage
      • Not FDA approved (Antihelios™), available on internet
    • Physical blockers: scatter UV radiation
    • broad spectrum UVA and UVB protection
    • titanium dioxide and zinc oxide
    • Good for sensitive skin
  • Sunblock Use
    • Apply ~20 minutes prior to sun-exposure.
    • Apply to all sun-exposed areas. Don't forget lips, ears, back of neck, or back of legs.
    • Apply a sufficient coat of sunscreen- most common mistake is being too stingy
    • Reapply every 2 hours when out in the sun- more frequently if in water or sweating
