SPF Myths Debunked: What Your Sunscreen Actually Does

Sunscreen is the single most important anti-aging product you can use. Let us debunk the biggest myths.

Myth: SPF 50 is twice as good as SPF 30

SPF 30 blocks about 97% of UVB rays. SPF 50 blocks about 98%. The bigger factor is how often you reapply.

Myth: You do not need sunscreen indoors

UVA rays penetrate glass. If you sit near windows, you are getting UV exposure.

Myth: Chemical sunscreens are dangerous

Both chemical and mineral sunscreens are safe and effective. The best sunscreen is the one you will actually wear.

Myth: You only need to apply once

Reapply every 2 hours outdoors. For indoor days, a midday touch-up is sufficient.

Our Recommendation

Use broad-spectrum SPF 30-50 every morning, 365 days a year. Consistency beats perfection.
