What is the recommended minimum SPF for daily use?

The recommended minimum SPF for daily use is SPF 30. This level of sun protection is widely endorsed by dermatologists and health organizations because it blocks approximately 97% of UVB rays, which are the primary cause of sunburn and contribute to skin cancer. Using an SPF 30 product provides a good balance of protection for daily activities without excessive product application.

While lower SPFs, such as 15 or 20, offer some level of protection, they may not adequately defend against the cumulative effects of sun exposure over time, especially for individuals who spend extended periods outdoors or have fair skin. SPF 50, while offering slightly more protection, may lead to a false sense of security and could result in less frequent reapplication, which undermines overall sun protection efficacy. Thus, SPF 30 is generally deemed the most appropriate minimum for effective daily sun protection.
