Your Everyday Guide to Sunscreen
Sunscreen labels are full of numbers and terms that can feel like a test. You do not need to memorize them all. A handful of basics will carry you through almost every situation.
What to look for on the label
Choose a product labeled broad-spectrum, which means it is designed to protect against both UVA and UVB rays. Most public health guidance suggests SPF 30 or higher for daily use. If you will be swimming or sweating, pick one labeled water-resistant.
Mineral or chemical?
Mineral sunscreens use ingredients like zinc oxide or titanium dioxide. Others use filters that absorb UV light. Both types can work well. The best one is the one you are happy to wear every day, so let texture and comfort guide you.
How to apply it
Apply sunscreen as the last step of your skin-care routine, before makeup. Use a generous amount, cover the face, neck, ears and any exposed skin, and give it a few minutes to set.
When to reapply
Sunscreen does not last all day. When you are outdoors, reapply about every two hours and after swimming, heavy sweating or towel drying. For days mostly indoors, morning application plus a top-up before heading out is a practical approach.
Common slip-ups
People often apply too little, forget reapplication, or skip sunscreen when it is cloudy. Another easy miss is the lips: an SPF lip balm handles that.
Check the date
Sunscreen has a shelf life. If a bottle is past its expiry date, or has been baking in a hot car all summer, replace it.
More than a bottle
Sunscreen is one tool among several. Wide-brimmed hats, sunglasses, long sleeves and staying in the shade around midday all reduce exposure. Using them together means you rely less on any single layer.
Children and sensitive skin
Young children and people with sensitive skin may need specific products. Read the label carefully and ask a pharmacist if you are unsure.
The best sunscreen habit is a boring one: the same product, every day, applied generously.
