Sunscreen Is Your Best Anti-Aging Product
The 80 Percent Rule
Up to 80 percent of visible facial aging is caused by UV exposure, not genetics. Daily sunscreen is the single most effective anti-aging step.
UVA vs UVB
UVB causes sunburn. UVA penetrates deeper, breaking down collagen year-round, even through clouds and windows. Broad-spectrum blocks both.
SPF Explained
SPF 30 blocks 97 percent of UVB. SPF 50 blocks 98 percent. Proper application matters more than higher numbers. Most people apply only 25-50 percent of the needed amount.
Correct Application
- Full teaspoon for face and neck
- Apply 15 min before exposure
- Reapply every 2 hours outdoors
- Do not skip cloudy days
