    SPF (Sun Protection Factor) indicates how long it takes for your skin to start burning compared to without sunscreen. SPF 70 provides a high level of protection against UVB rays, which are primarily responsible for sunburn and skin cancer. However, it’s essential to understand that no sunscreen can block 100% of UV rays. SPF 70 blocks about 98.6% of UVB rays, leaving a small percentage that can still reach your skin.

    While SPF 70 offers significant protection, it doesn’t guarantee that you won’t tan. Tanning occurs due to exposure to UVA rays, which can penetrate deeper into the skin. Even with high SPF sunscreen, some UVA rays can still get through, leading to tanning. Therefore, while SPF 70 can help reduce the risk of sunburn and skin damage, it may not completely prevent tanning, especially with prolonged sun exposure.

    To minimize tanning, in addition to using sunscreen, consider other sun protection measures like seeking shade during peak sun hours, wearing protective clothing, and using hats and sunglasses. These actions can complement the protection provided by SPF 70 sunscreen, helping you enjoy the outdoors while reducing the risk of excessive tanning and skin damage.
