What does SPF stand for?

Sun Protection Factor
Skin Preservation Formula
Sun Prevention Factor
Skin Protection Factor

The correct answer is: Sun Protection Factor

SPF stands for Sun Protection Factor. This term is used to quantify the level of protection provided by sunscreens against ultraviolet (UV) rays, specifically UVB rays, which are primarily responsible for sunburn and contribute to skin cancer risk. The SPF number indicates the amount of time it would take for skin to burn while using the sunscreen compared to when not using it. For example, if a person would normally burn after 10 minutes of sun exposure, an SPF of 30 theoretically allows for 30 times longer exposure to the sun without burning, making it crucial for proper sun safety practices. The other terms, while they might seem plausible, do not accurately represent the standardized terminology used in the context of sun protection. Skin Preservation Formula, Sun Prevention Factor, and Skin Protection Factor do not have the same recognized meaning as Sun Protection Factor and would not be found on sunscreen labels or in skincare guidelines.
