Waterproof vs Water-Resistant Sunscreen

Water-resistant sunscreens tend to last in the water, remaining effective for 40 to 80 minutes depending on the label designation.

What is the difference between waterproof and water-resistant sunscreen?

Water-resistant sunscreens tend to last in the water, remaining effective for 40 to 80 minutes depending on the label designation. Sunscreens are not considered “waterproof” as all will eventually wear off if in the water long enough. I tend to favor La Roche Posay Anthelios lotion spray sunscreen for swimming.

What ingredients should people look for in water-resistant sunscreen?

Usually, water-resistant and very water-resistant sunscreens include polymers such as dimethicone and/or lipophilic ingredients such as waxes and oils. These ingredients are not attracted to water and are left behind on the skin when exposed to sweat or water.

What makes water-resistant sunscreen effective?

Water-resistant sunscreens are effective by extending their SPF protection in spite of water exposure. The added polymers and lipophilic ingredients hold the sunscreen to the skin for longer to permit this coverage.

Do you have any product recommendations for water-resistant sunscreens?

Neutrogena Ultra Sheer Mineral Sunscreen Stick is both very water resistant (lasts 80 minutes) and contains a physical sunscreen, zinc. This is reliable UV protection along with the ability to last longer than many other products.

I tend to favor La Roche Posay Anthelios lotion spray sunscreen for swimming as it is easier to re-apply.
