3 Common Misconceptions About Sunscreen — May 25, 2020

3 Common Misconceptions About Sunscreen

3 common misconceptions about sunscreen.

1) I don’t need sunscreen when it’s cool outside.  This is absolutely wrong.  May is the month I see the most sunburns, and the reason is because you don’t think about sunscreen if it’s not hot.

2) I don’t need sunscreen if I’m in the shade. Actually, you are still getting about 90% of the normal UV rays.

3) I applied my sunscreen before I left home, so I’m good for the afternoon.  If you’re sweating or in the water, sunscreen is gone in 60 to 90 minutes.

For more good sunscreen advice, talk to your dermatologist.

Sunscreens: Separating Fact from Fiction — June 30, 2017

Sunscreens: Separating Fact from Fiction

Sunblock stripes

1) Myth:  Sunscreens are toxic.  The most common unblocking ingredients, zinc oxide and titanium dioxide are probably safer than most of your cleansers and cosmetics.

2) Myth: Organic is better.  Actually sunscreens are divided into 2 groups.  So-called chemical sunscreens absorb the sun’s rays (Oxybenzone or Avobenzone).  Physical sunscreens block or deflect the sun (Zinc Oxide or Titanium Dioxide).  Both forms are very effective and are much safer than sunburns.  

3) Myth: Sunscreens disrupt body hormones.  This is not true as there is simply not enough absorption.

4) Truth:  Sunscreens can also moisturize, and some contain peptides and other products to nourish your skin.  

5)Truth: A few people are allergic to certain components in some sunscreens, but most can use zinc oxide products.

The beach today was great. You had a wonderful time, and now you have the mother of all sunburns.  AND IT HURTS!  What to do?  


1) Cool your skin with a nice air conditioned environment.  

2) For mild sunburn, topical steroids such as 1% hydrocortisone for 2 or 3 days may relieve discomfort.

3) For more severe burns, Ibuprofen 400 mg 2 times a day coupled with Neosporin 2-3 times a day may provide relief.  

4) For severe burns, see your dermatologist.  

5) Keep skin moisturized while healing, and remember you are more prone to burns while healing.
