SPF and Skin: When to Use It, and Why You Should Never Cover It
We often hear that SPF (Sun Protection Factor) should be applied daily, but do we really know when and how to use it correctly? And more importantly, why should you not apply other products over it? Here's what you need to know to effectively protect your skin.
When should you use SPF?
Contrary to popular belief, SPF is not just for beach days. UV rays are present all year round, even when it's cloudy, even in winter, and even indoors if you are exposed to natural light (near a window, for example).
Here's when to apply SPF:
- Every morning, after your skincare routine (moisturizer, serum, etc.)
- Even on cloudy days (up to 80% of UV rays penetrate clouds)
- Even indoors if you are near a natural light source
- Even more important in summer, in the mountains, or by the water
Why is SPF essential?
SPF protects the skin from UV rays, which are responsible for:
- Premature skin aging (wrinkles, loss of elasticity)
- Pigment spots
- Sunburn
- And more seriously, the risk of skin cancer
A good SPF, used correctly, is one of the most powerful actions to preserve the health and youthfulness of your skin.
Never Cover SPF: Why?
It's a common mistake: applying foundation, powder, or cream after your SPF.
Here's why it's not recommended:
A product applied over SPF can alter its protective barrier. It can dilute or move the sunscreen, which reduces its effectiveness.
SPF should always be the last step in your skincare routine.
If you want to wear makeup, opt for makeup that itself contains SPF or very light products, patted (not rubbed), to limit the displacement of the filter.
In summary: The right SPF routine
Cleanse and moisturize your skin as usual.
Apply a generous layer of at least SPF 30, SPF 50 recommended.
Reapply every 2 to 3 hours if you are directly exposed to the sun.
Today, there are very light, non-greasy, and invisible sunscreens, perfect for daily use, even under light makeup.
Protecting your skin from the sun is not a luxury; it's an essential habit to adopt every day to keep your skin healthy, young, and radiant.
Remember, your best anti-aging product is your SPF.
