How to Choose the Right Sunscreen for Your Skin
What SPF means, the difference between mineral and chemical filters, and how much to apply for real protection.

Understand SPF and broad spectrum
SPF measures protection against UVB rays, which cause sunburn. SPF 30 blocks about 97 percent of UVB and SPF 50 blocks about 98 percent. No sunscreen blocks everything, so shade and clothing still matter. Look for the words broad spectrum, which means the product also protects against UVA rays that contribute to skin aging.
Mineral and chemical filters
Mineral sunscreens use zinc oxide or titanium dioxide, which sit on the skin and reflect UV light. They tend to suit sensitive skin but can leave a white cast. Chemical sunscreens use filters that absorb UV light. They are usually lighter and blend in more easily, but some people find they sting around the eyes. Both types work when applied correctly, so choose the one you will actually wear every day.
Match the formula to your skin
- Oily or acne-prone skin: look for gels or fluids labeled non-comedogenic.
- Dry skin: creams with added moisturizers feel more comfortable.
- Sensitive skin: try fragrance-free mineral formulas.
- Active days: choose a water-resistant product and reapply after swimming or sweating.
Apply enough, and reapply
Most people use far less than they need. A common guide is about two finger-lengths for the face and neck. Apply it 15 minutes before going outside and reapply about every two hours when outdoors, and after swimming or heavy sweating.
