SPF stands for Sun Protection Factor—it measures how well a sunscreen protects your skin from UVB rays, the type of radiation that causes sunburn and contributes to skin cancer.
Sunscreen with SPF is essential because it acts as a protective barrier between your skin and the sun’s harmful rays. Here’s why you need both:
Why Use Sunscreen?
• Shields your skin from harmful UVA and UVB rays
• Prevents sunburn, tanning, and painful peeling
• Reduces the risk of skin cancer
• Slows down visible signs of aging like wrinkles, fine lines, and dark spots
• Maintains your skin barrier and promotes an even skin tone
• UV rays weaken blood vessel walls and break down collagen in the skin, which can lead to broken capillaries, especially in people with sensitive or fair skin.
Why SPF Matters
• SPF indicates how well the sunscreen blocks UVB rays (the ones that burn the skin)
• The higher the SPF, the stronger the protection—especially crucial in sunny climates like Lahore/Pakistan
• Essential for long outdoor exposure, even on cloudy days
Sunscreen = physical barrier
SPF = strength of that barrier
How SPF Works
• SPF 15: blocks ~93% of UVB rays
• SPF 30: blocks ~97%
• SPF 50: blocks ~98%
• SPF 100: blocks ~99%
Important Notes
• SPF only measures UVB protection, not UVA.
• Always choose “broad-spectrum” sunscreen to ensure protection against both UVA (aging) and UVB (burning) rays.
