Before understanding Sunscreen, you need to have a clear idea about SPF. SPF, or Sun Protection Factor, measures how well a sunscreen will protect skin from UVB rays and other kinds of radiation that damage our skin, cause sunburn, and eventually lead to skin cancer.

To know the SPF factor of a sunscreen several laboratory tests are carried out on an untanned patch of a human volunteer. In this step, sunscreen is applied to the skin patch and then they are exposed to UV lamp-simulated sunlight. The number of seconds taken by the skin patch to slightly redden when covered in sunscreen is divided by the number of seconds it takes when no sunscreen is applied to determine the value of SPF. 

According to India’s Ministry of Consumers Affairs, sunscreen must have a SPF ranging between 22.46 to 34.66. 

A SPF also defines the time our skin can stay in the sunlight without burning. For example, If your skin normally burns after 10 minutes of being in the sun, applying an SPF 30 sunscreen would allow you to stay in the sun without burning for approximately 300 minutes.
