What is the purpose of SPF in skincare?

• A. To enhance skin hydration
• B. To protect the skin from harmful UV rays
• C. To improve skin texture
• D. To promote collagen production

Answer: (B)

The purpose of SPF, or Sun Protection Factor, in skincare is to protect the skin from harmful UV rays. UV radiation from the sun can lead to skin damage, premature aging, and various skin conditions, including certain types of skin cancer. The SPF rating indicates the level of protection that a sunscreen provides against UVB rays, which are primarily responsible for sunburn and contribute to skin cancer risk. A higher SPF means greater protection, allowing individuals to spend more time in the sun without burning. It is essential for maintaining overall skin health, particularly for those who may be exposed to the sun for extended periods or have skin that is more susceptible to UV damage.
