SPF15

SPF15, or Sun Protection Factor 15, is a measure of the effectiveness of a sunscreen in protecting the skin from ultraviolet (UV) radiation. It indicates that the sunscreen will prevent 93.3% of UVB rays from reaching the skin. UVB rays are primarily responsible for sunburns and skin damage. SPF15 is considered a moderate level of protection and is suitable for casual outdoor activities. However, it is important to note that no sunscreen provides 100% protection, and the SPF rating decreases over time as the sunscreen is exposed to the sun. Reapplication is necessary after swimming or sweating, as these activities can reduce the sunscreen's effectiveness. SPF15 sunscreens are widely available and are often used by people who do not require high levels of sun protection. It is recommended to use a sunscreen with at least SPF15 for all outdoor activities, regardless of the time of year or the strength of the sun. Additionally, it is important to apply sunscreen generously and evenly, and to reapply it as needed.
