Why Daily SPF Is the Most Important Step in Your Skincare Routine
Did you know your daily SPF is the most important step in your entire skincare routine? Not only does it help defend against skin cancer, but it also targets premature aging. SPF isn’t just for summer — here’s what you need to know.
Know Your Rays
There are different types of UV rays that contribute to skin damage and cancer:
- UVA (The Aging Rays): Penetrate deeply and contribute to up to 85% of visible aging like wrinkles and dark spots.
- UVB (The Burning Rays): Affect the outer layers of skin and are responsible for sunburns and surface-level damage.
Both are harmful — finding an SPF that protects against both is essential.
Broad Spectrum Protection
SPF specifically measures protection against UVB rays, not UVA. To shield your skin from both, choose an SPF labeled Broad Spectrum. It’s the ultimate way to preserve your skincare progress and protect your skin.
One of our favorites, Dr. Loretta Universal Glow Daily Defense Mineral Sunscreen Fluid SPF 40 , is a lightweight moisturizer + full-spectrum SPF duo, perfect for hot summer days.
Importance of SPF Indoors
Think you're only exposed to UV damage outdoors? UVA rays can penetrate glass, meaning your skin is still vulnerable indoors. Make SPF a part of your daily ritual — no matter where your day takes you.
What Your SPF Rating Really Means
The number on your SPF isn’t about how long you're protected — it’s about the percentage of UVB rays it blocks:
- SPF 15 blocks up to 93% of UVB rays
- SPF 30 blocks up to 97% of UVB rays
- SPF 50 blocks up to 98% of UVB rays
No SPF blocks 100%, and the difference between 30 and 50 is small. Find one you love and apply it daily — consistency matters more than the number.
Your Guide to Picking and Applying
The best sunscreen for you is the one you'll actually wear. Here’s how to make it a daily habit:
- Choose Wisely: Pick a Broad Spectrum SPF 30+ for daily use. Going to be in direct sun? Choose SPF 50.
- Don't Be Shy: Use enough product — two full finger lengths for face, neck, and chest; two tablespoons for the body.
- Reapply: Reapply every two hours, especially after sweating, swimming, or toweling off.
