Furthermore, sunscreens that claim to be water resistant must report how long the use can expected to benefit from the product’s SPF level of protection while swimming or sweating. There will be two choices – 40 minutes or 80 minutes. In addition, manufactures no longer can claim that sunscreens are waterproof, sweat proof or sun blocks. Sunscreens also can’t claim that they protect the skin immediately on application or last for more than two hours without reapplication unless data to substantiate that claim is approved by the FDA.
The AAD recommends that you and your family members should try to use a water-resistant, broad-spectrum sunscreen, which protects against both types of ultraviolet radiation. Aim for an SPF of 30 or higher when buying sunscreen. You should also consider limiting sun exposure and finding the shade whenever possible. Also, wear clothes that protect you from the sun’s rays, including hats and sunglasses.
