The term "Foundation + SPF15" typically refers to a type of cosmetic product that combines the benefits of foundation, which is used to even out skin tone and provide coverage, with sun protection factor (SPF) 15, which helps protect the skin from the harmful effects of the sun's ultraviolet (UV) rays.SPF15 indicates that the product provides a moderate level of sun protection. It means that the product can filter out approximately 93% of the sun's UVB rays, which are responsible for causing sunburn. However, it's important to note that SPF only measures protection against UVB rays and does not provide a complete indication of protection against UVA rays, which also contribute to skin damage.When using a foundation with SPF15, it's essential to keep in mind that the sun protection provided may not be sufficient for extended periods of sun exposure, particularly during peak sunlight hours. For comprehensive sun protection, it is recommended to use a dedicated sunscreen with a higher SPF, broad-spectrum protection (covering both UVA and UVB rays), and reapply it regularly.Remember that even if you're using a foundation with SPF15, it's still beneficial to follow other sun protection measures such as seeking shade, wearing protective clothing, and using sunglasses to shield your eyes from the sun's rays.
