Sun Protection Sample SPF Test

Understanding of SPF

SPF (Sun Protection Factor) signifies the level of sun protection provided by sunscreen. It measures the amount of sunlight's ultraviolet rays that can penetrate the skin. In simple terms, a higher SPF indicates better sun protection.

In the business product, the SPF value is an integer, and the calculation formula is:

SPF = Sunburn radiation dose after sunscreen / Sunburn radiation dose without sunscreen

This calculation is based on applying 2 milligrams of sunscreen per square centimeter of skin surface.

For example, if skin covered with sunscreen will burn after 300 seconds of UV exposure, and skin without sunscreen will burn after 10 seconds of UV exposure, then the SPF value is 300 divided by 10, which equals 30.
