Are there any swimsuits that have sun protection properties so I to use sunscreen underneath them?

Yes, there are swimsuits specifically designed with ultraviolet protection factor (UPF) properties to protect your skin from harmful ultraviolet (UV) rays from the sun while you're in the water or enjoying outdoor activities near water. While sunscreen is still an important element of sun protection, these swimsuits offer an additional layer of protection.

UPF swimwear can block a significant portion of both UVA and UVB rays. The higher the UPF value, the greater the protection provided by the swimsuit. Look for swimsuits with a UPF rating of 50+ for optimal protection. Some swimsuits may also come with additional features like long sleeves, high necklines, and wide-brimmed hats for enhanced sun protection.

Here are some factors to consider when choosing a UPF swimsuit:

1. UPF Rating: Ensure the swimsuit has a UPF rating of 50+ to ensure adequate protection from UV rays.

2. Coverage: Opt for swimsuits that provide full coverage to cover arms, legs, and other sun-exposed areas.

3. Fabric Construction: Look for swimsuits made from tightly woven fabrics, as they tend to offer better UPF protection.

4. Color: Darker colors tend to provide better sun protection than lighter colors.

5. Fit: Make sure the swimsuit fits snugly without being too tight, allowing maximum protection over the covered areas.

Remember, using a UPF swimsuit does not eliminate the need for sunscreen. Be sure to apply and reapply sunscreen regularly, especially if the swimsuit becomes wet, as its UPF protection properties could potentially diminish when wet. Also, seek shade at certain times of the day, limit exposure to the sun during peak UV hours, and wear UV-protective sunglasses with wide-brimmed hats for overall sun safety.
