Detailed answer

Using body lotion with SPF is better because it helps protect the skin from harmful UV rays that can cause sunburn, premature aging, and skin cancer. SPF (Sun Protection Factor) is a measure of how well a product protects the skin from UVB rays, which are primarily responsible for sunburn. By using body lotion with SPF, you can ensure that your skin is shielded from the damaging effects of the sun. However, it's important to note that SPF in body lotion may not be as effective as dedicated sunscreen, so it's recommended to also use a separate broad-spectrum sunscreen for extended periods of sun exposure or during outdoor activities.
