The U.S. Federal Food and Drug Administration found that 20 percent of lab animals studied in a sunscreen investigation developed faster growing skin cancer lesions and tumors than those animals not applied with the sunscreen ingredient.

Retinyl palmitate is commonly found in sunscreen and is derived from Vitamin D. In the experiment, the cream was applied to the animals’ skin and then the animals and a control group of animals were exposed to the equivalent of 10 minutes of sunshine daily over a year.
The animals grew tumors 20 percent faster than the control group, suggesting a connection between the cream and skin cancer.
According to Nutritionalist and Author Robert Redfern, an alternative to sunscreen to prevent cancer is natural sunscreen, supplements of Astaxanthin, Vitamin D and plenty of Essential Fatty Acids, and people should stay out of the midday sun.
