What is SPF?
SPF isn’t an ingredient. It’s a number that measures how well a product protects against UVB rays, the main cause of sunburn. The real protection comes from the UV filters in the formula. That means a product without an SPF rating offers no proven sun protection.
Why does sunscreen matter?
• It reduces sunburn, dark spots and melasma.
• It slows visible signs of aging. In an Australian clinical trial, people who used sunscreen daily showed 24% less skin aging than occasional users.
• It lowers the risk of skin cancer.
• Choose a Broad Spectrum product that covers both UVA and UVB, with SPF 30 or higher.
Are UV filters harmful?
Approved filters are safe at permitted concentrations, but a few things are worth knowing:
• Some chemical filters can irritate sensitive skin.
• European regulators have lowered the maximum allowed levels of certain filters, such as Oxybenzone and Octocrylene, as a precaution.
• Mineral filters (Zinc Oxide and Titanium Dioxide) are gentle on sensitive skin but may leave a light white cast.
Can a product without SPF protect you just as well?
No. Natural oils like carrot seed and coconut oil showed very weak protection when tested on human skin. Antioxidants such as Vitamin C, Vitamin E and Niacinamide help skin repair sun damage, but they don’t block UV rays. They work alongside sunscreen, not in place of it.
The Better Skin Tip To protect:
use a tested SPF sunscreen, apply enough of it, and reapply every 2 hours when you’re in the sun.
To boost: apply an antioxidant serum in the morning, before your sunscreen, for extra defense.
