The sun protection factor, known as SPF, only blocks UVB rays and not UVA rays, which are the most damaging rays. Everyone should wear SPF 30. It should be applied 30 minutes before sun exposure, and it should be reapplied approximately every 2 hours.
- SPF 30 blocks 96% of the sun’s UVB rays
- SPF 15 blocks 92% of the sun’s UVB rays
In choosing a sunscreen lotion or spray, it is easy to feel lost in the list of ingredients on the package. Avoid any sunscreens with mineral oil included. Mineral oil does more harm than good to the skin.
Your goal should be to block the UVA rays. To do this, find a source of SUNBLOCK, not sunscreen. Look for these ingredients in the proper concentration to block UVA and UVB rays:
- Parasol (avobenzone) or Mexoryl in concentrations of 3%
- Zinc Oxide 7.5% or Titanium Dioxide 7.5%, if they are listed alone. Less concentrations of each are needed if they are in combined products.
It is important to use the proper sunblock every day of the year, and you should apply frequently to all exposed areas.
Supplements can also assist. It is important to take antioxidants to fight free radicals and reduce abnormal cell growth, which is the damage to cells from the sun and other toxins. With the proper use of sunblock, we must ensure we have adequate intake of Vitamin D. Please call me for further evaluation.
