Let's Talk About Year Around Sunscreens!

Part I

Sunscreen Considerations: ​Chemical vs. Mineral

The FDA has found absorption of some of the  chemicals from sunscreens into our bodies beyond the allowed amount of 0.5 ng/ml. Their effect is unknown. The chemicals of concern are:

                                            

         avobensone                 ecamsule                octocrylate               octisalate                 oxibenzone       

Mineral sunscreens include the ingredients titanium dioxide and/or zinc oxide. When applied, they do not enter the body but absorb UV rays. Chemical sunscreens absorb the UV rays and can be absorbed into the body.

More studies will be done but in the meantime, continue using your sunscreen for protection.

You can ALSO:

  1. Wear clothing and hats manufactured for sun protection

  2. Avoid peak UV times of the day (11am -2pm)

  3. Take advantage of shady areas when you can

  4. Wear sunglasses that offer UV protection

  5. Begin to wear hats if you have thinning or loss of hair 

Let's Talk About Sunscreens Part 2

Use The Following Criteria When Choosing a Sunscreen

Choose a company/brand that has a history in SKIN CARE not sun tanning.

Neutrogena, Aveeno, Elta, ​Blue Lizard are very reputable companies

Is this sunscreen for the face or the body?

A less expensive​ sunscreen can be used on the body with an oily or zinc base

Is your face oily, dry, normal or combo?

Your sunscreen should leave a matte finish on your face, not oily or too dry

Are the ingredients natural or in question?

Zinc is organic. Chemicals are a concern but their safety hasn't been studied yet.​

Do you have skin of color?

To avoid a whitish or bluish appearance, the zinc needs to be tinted and micronized. The chemical sunscreens that do not give the bluish appearance unfortunately are under FDA scrutiny.
