This is based on the results of animal studies. Test animal coated with mixture of retinyl palmitate and skin cream and exposed to ultraviolet light.

I cannot find any data on occurrence to humans. But any product of doubt should be avoided. Refrain from using any skin cream with retinyl palmitate content.

Synthetic Vitamin A is added skin cream as anti-aging agent. The development of cancer will really make anyone stop aging – you know what I mean.
