hi, what is the best sun block cream ?

Anon - Here is the opinion of the Skin Cancer Foundation.
"...We...have come to the conclusion that there is no scientific evidence to support claims that retinyl palmitate (vitamin A) is a photocarcinogen in humans. Our photobiologists are unaware of any evidence that supports the relationship between the use of sunscreen containing retinyl palmitate and an increased risk of skin cancer.

When used as directed, sunscreen products are safe and effective. Since our inception, The Skin Cancer Foundation has always recommended using a sunscreen with an SPF 15 or higher as one important part of a complete sun protection regimen which includes seeking the shade and covering up with clothing."

Hi Anonymous

This is a very hard question to answer right now, as there is some debate about the safety of certain ingredients in sunscreen: https://www.empowher.com/cancer/content/senator-urges-fda-rule-key-sunscreen-ingredient-linked-skin-cancer.

You may want to limit your exposure, wear a hat and sunglasses, and avoid products containing retinyl palmitate until this is sorted out.

You asked a difficult question, and at this time we will monitor an further decisions made by the FDA on this matter. Thanks for writing.
