Sun Jam

The Sun Jam Company created the first "tan through" skin cream, Sun Jam. The Sun Jamming app was created to help everyone enjoy the sun and learn about safe tanning. The sun's UVB rays are the rays that make Vitamin D. The UVA rays are the rays that don't produce Vitamin D. Use the sun chart to find the times of the day that the sun's UVB rays are available. Months may go by without any UVB rays being available and UVB rays are also effected by weather conditions like clouds and rain, etc.
