This sunscreen comes highly recommended by Dr. Marcus for its mineral-based formula. Mineral sunscreens use active ingredients such as zinc oxide and titanium dioxide, which serve as a physical barrier to block UV rays. (By contrast, chemical sunscreens absorb into the skin.)
This one has 8 percent titanium dioxide and 10 percent zinc oxide to protect against both UVA and UVB rays.
Not only is it easily spreadable, it "absorbs well into the skin," Dr. Marcus says.
It also offers 80 minutes of sweat- and water-resistance, and it's free of parabens and fragrance, making it ideal for all skin types, including sensitive skin.

What to Look for in Waterproof Sunscreens
Here are some features to keep in mind when shopping for water-resistant sunscreens.
1. Ingredients
Not all water-resistant sunscreens are made the same, so you'll want to choose ones with active ingredients that block UV rays, such as zinc oxide and titanium dioxide.
Watch out for ingredients that can irritate the skin like fragrance, parabens and chemical filters.
Additionally, it's best to look for a formula that states it is non-comedogenic, so it will not clog pores and potentially contribute to acne breakouts, Dr. Marcus says.
2. SPF
SPF, also known as the sun protection factor, is an indicator of how well your sunscreen protects against UVB rays.
According to Dr. Marcus, sunscreens should be SPF 30 or higher.
It's important to note that a higher SPF does not mean more protection. For best protection, it's best to reapply several times throughout the day and follow the product's instructions.
3. Duration of Water-Resistance
Water-resistant sunscreens will have a water-resistance duration printed on the label, usually ranging between 40 and 80 minutes.
If a product is water-resistant for 80 minutes, you should reapply a little before the 80-minute window ends for the best protection.
