There’s one product I will never skip—and I say this not only as a skincare professional, but as someone who wants your skin to look radiant for years to come.
It’s not your fancy serum.
It’s not your moisturiser.
It’s your SPF.
Daily sun protection is the single most powerful step in your skincare routine—and no matter your age, skin tone, or lifestyle, SPF is not optional. Let’s talk about why.
Why is SPF so important?
SPF (Sun Protection Factor) shields your skin from UV rays—the number one cause of premature aging, pigmentation and skin cancer. And no, it doesn’t have to be a sunny day for UV to do damage. Up to 80% of UV rays can still reach your skin through clouds, windows, or even when you’re driving.
There are two main types of UV rays:
- UVA: Think A for aging – penetrates deep into the skin, breaking down collagen and speeding up wrinkles and pigmentation.
- UVB: Think B for burning – causes sunburn, redness and can directly damage your DNA.
SPF protects against both. Without it, even the best products in your routine won’t work the way they should.
What Does the Number Actually Mean?
SPF 30 doesn’t mean you can be in the sun for 30 minutes—it means it filters out about 97% of UVB rays. SPF 50 blocks around 98%. The higher the number, the better—but what matters most is consistency and reapplication.
Mineral vs. Chemical Sunscreen
- Mineral (Physical): Contains zinc oxide or titanium dioxide. Sits on the skin and reflects UV rays. Great for sensitive skin or those prone to breakouts.
- Chemical: Absorbs UV rays and transforms them into heat. Often feels lighter and more sheer—perfect under makeup.
Somatologist Tips: How to Get the Most Out of Your SPF
✔ Use a full teaspoon for face, neck and ears
✔ Apply 15 minutes before sun exposure
✔ Reapply every 2 hours, or immediately after sweating or swimming
✔ Don’t forget ears, eyelids and hands—they age just as fast!
✔ Wear SPF even indoors if you’re near windows or screens
Did You Know?
- Blue light from screens (phones, laptops) can also lead to pigmentation—yes, SPF helps with that too.
- Melanin-rich skin can still burn and is prone to post-inflammatory hyperpigmentation without sun protection.
- Retinol and AHA/BHA all make your skin more sun-sensitive. Skipping SPF cancels out their benefits.
Final Word: Don’t Invest in Skincare Without Protecting It
Your skin deserves protection—not just on holiday, but every single day. SPF is more than a sunscreen—it’s your skin’s bodyguard, its insurance policy, its first line of defense.
Make SPF Your Non-Negotiable, because aging gracefully starts with protection - every single morning.
