Sunscreens: Protect Your Skin and Prevent Aging Before You Have To

It’s May, and the weather is finally spring-like. With Governor Murphy opening up the state parks this past weekend, it was all on board for some enjoyable time in the sun. People were out and parking lots were relatively full, social distancing aside. Having been quarantined for 6 weeks already here in New Jersey, it’s easy to forget your routine of applying sunscreen before leaving the house. Remember that light penetrates through (car) windows. So, even if you are not outside but you are sitting next to a window, please apply your sunscreen.

So, here are some fun facts:

  • Apply your sunscreen (see below) 20 minutes before going out- even in cloudy weather and reapply every 2 hours or after swimming and excessive sweating
  • The sun’s rays are strongest between 10 AM and 2 PM, so stay in the shade if you can
  • Use 1 ounce (2 tablespoons) evenly distributed each time you apply (you may use less if you are not wearing a bathing suit or skimpy clothes)
  • Remember water, sand and snow reflect sunlight, so wear sunscreen, even if it is cold.
  • SPF 30 blocks 97% of the sun’s harmful rays. SPF 50 blocks 98% of the sun’s harmful rays. Always use SPF of 30 or higher.
  • If you use an antioxidant containing Vitamins C and E (such as  SkinCeuticals CE Ferulic)  you can increase the efficacy of your sunscreen by 4 times—this means better protection, NOT more time in the sun
  • 90% of visible aging is caused by sun damage.

There are 2 types of sunscreens: chemical and physical. Here are the differences:

Physical

Pros:

  • Broad Spectrum-protects against both UVA and UVB
  • Less likely to irritate “sensitive “skin
  • Less likely to clog pores – so it’s better for acne-prone skin
  • Will be effective immediately

Cons:

  • May leave a whitish tint on the skin
  • Rubs off more easily, so may require more frequent application

Chemical

Pros:

  • Easier application since it is typically thinner

Cons:

  • Needs to be applied 20-30 minutes before exposure (this is because chemical sunscreens actually react with the skin causing the UV radiation to become deactivated and release heat. It takes a few minutes before exposure to set up this reaction
  • Maybe more irritating to sensitive skin especially with higher SPF’s
  • More likely to clog pores

Here at the True Beauty Med Spa, we love the eltaMD® physical sunblock and the ZO® sunscreen.
