Avoid sunscreens with potentially harmful ingredients
Use a sunscreen with a minimum of SPF 15 and a maximum of SPF 50;
Make sure labels list UVA and UVB (or broad spectrum protection);
Avoid products containing oxybenzone and retinyl palminate if you're concerned about potentially toxic chemicals;
Choose lotions versus spray sunscreens for a more evenly distributed protection.
Remember to apply at least 2 ounces of lotion (about a shot glass full) and reapply often. The sun breaks down the ingredients in sunscreen that protect your skin. Experts recommend reapplying every two hours, or after swimming or heavy sweating.
Choose sunscreens with natural minerals
