What is the FDA-recommended minimum SPF protection?

The recommended minimum SPF protection by the FDA is SPF 15. This level of sun protection factor is considered sufficient for most individuals to reduce the risk of skin damage caused by UVB rays, which are primarily responsible for sunburn and contribute to skin cancer development. SPF 15 blocks approximately 93% of UVB rays, making it a practical choice for daily use, particularly when combined with other sun safety practices, such as wearing protective clothing and seeking shade.

Higher SPF values do offer increased protection, but an SPF of 15 is generally adequate for everyday activities, as long as it is reapplied appropriately and used in conjunction with other protective measures. It's important to note that while higher SPFs can provide additional protection, they may also create a false sense of security, leading to prolonged sun exposure without reapplication, which can counteract the benefits.
