SPF Is Insurance: The Math Behind Sun Protection

Here is a number that should change how you think about sunscreen: UV radiation is responsible for up to 80% of visible skin aging. That means wrinkles, dark spots, loss of firmness, and uneven texture are primarily caused by something you can prevent — for about $1 a day.

How Good Is Your SPF Game?

The Cost of UV Damage vs. Prevention

Treating sun damage after the fact is dramatically more expensive than preventing it. Use the calculator below to compare the annual cost of good sunscreen vs. the treatments needed to reverse UV damage.

SPF Basics That Actually Matter

• SPF 30 blocks 97% of UVB rays. SPF 50 blocks 98%. The difference is small.
• UVA penetrates windows. If you sit near windows, you need SPF indoors.
• Chemical and mineral sunscreens are both safe. The best one is the one you actually wear.
• Reapply every 2 hours outdoors. SPF powder or spray for midday touch-ups.
• Apply SPF as the last step of skincare, before makeup.

What to Look For

Choose broad-spectrum SPF 30-50. Look for formulas you enjoy wearing — if it feels good, you will use it. Tinted mineral sunscreens double as a light foundation and work beautifully on all skin tones. Our providers can recommend specific products during your next visit.
