The intensity of UVA radiations is fixed and the intensity of UVB radiations is subject to change. The intensity of UVB rays varies, and thus the SPF of a product is determined by its effectiveness in protecting against UVB radiation.
SPF is a good indicator of the protection offered by sunscreens against UVB rays. However it doesn’t guarantee protection from UVA. It’s best to buy broad-spectrum sunscreens with SPF 15-30. The SPF numbers do not indicate quality, but is rather a standard that measures the effectiveness of sunscreens.
The SPF of a sunblock product is measured under artificial conditions. A sunscreen that has a higher SPF can offer more protection from UVA radiation and claim to offer additional advantages.
