Overcast skies, mild temperatures, a successful beauty routine: serum, moisturizer, foundation. But have you thought about your sunscreen?
👉 If the answer is no, don't worry, you're not alone.
So, do we really need to apply sunscreen every day, even in the city? We'll explain everything!
Daily sunscreen use: why all the emphasis? 🧐

UV rays don't take days off.
Contrary to popular belief, UV rays (those sneaky ultraviolet rays) don't disappear as soon as the sun hides behind a cloud. In the city, even under a grey sky, up to 80% of UV rays can penetrate clouds.
Add to that the reflection off shop windows, concrete or even your computer screen if you are near a window… and boom, your skin is taking a dose of skin aggression without you even realizing it.
Accelerated skin aging? It's often due to the sun.
Wrinkles, fine lines, age spots, and loss of elasticity… guess who the main culprit is? Spoiler alert: it's neither your foundation nor your lack of sleep. The sun is responsible for approximately 80% of premature skin aging.
And this isn't just for mature skin. From the age of 25, skin starts to produce less collagen , and the effects of UV exposure become visible if we don't protect our hydrolipidic film.
Common misconceptions about sunscreen in the city ❌
“But I’m not at the beach…”
…and yet, you walk down the street, you wait for the bus, you have a coffee on a terrace. In short, your face is exposed to UV rays every day , even if you don't feel the sun's heat on your skin.
And beware: UV-A rays , the most insidious, penetrate the deep layers of the skin, causing invisible but lasting damage – wrinkles, sagging, age spots. They are even present through windows .
“I already wear a moisturizer, isn’t that enough?”
It's a good start, but no. Unless it contains an SPF of at least 30 , your moisturizer isn't enough to protect your skin. Even worse, some active ingredients like fruit acids, retinol, or vitamin C , while effective against blemishes and dullness, make the skin more sensitive to UV rays . Hence the importance of using a good sunscreen in addition.
What are the concrete benefits of using sunscreen daily? ✅
-
Preserve the radiance and evenness of the complexion
By preventing dark spots, it helps you maintain a bright and even complexion. -
Maintaining skin elasticity
Thanks to the prevention of oxidative stress, your skin retains its firmness for longer. -
Avoid blemishes and redness
UV rays cause inflammation, dilation of pores, and therefore more pimples or redness in acne-prone skin. -
Boost the effectiveness of your skincare
Well-protected skin responds better to your moisturizing, anti-aging or anti-blemish treatments.

FAQ: Should you wear sunscreen every day, even in the city? 💬
What if I work indoors all day?
Even indoors, UV-A rays pass through windows . So yes, at least some light protection is still recommended.
Can I use my foundation with SPF instead?
Better than nothing, but often not enough is applied to reach the stated SPF. It's better to use a proper sunscreen underneath .
Is it a good idea to apply sunscreen every day?
Absolutely! It's even essential if you want to preserve your skin's elasticity, youthfulness, and radiance. Applying sunscreen daily helps prevent wrinkles, dark spots, and even some inflammation. And contrary to popular belief, modern sunscreens don't suffocate the skin; on the contrary, they can even hydrate and soothe, depending on the active ingredients.
Is it acceptable to spend a day without sunscreen?
Technically, yes… but not ideal. A day without sunscreen is a day when your skin is exposed to the invisible damage of UV rays. A single exposure won't ruin everything, but in the long run, it adds up. It's better to make it a daily habit , like brushing your teeth or applying moisturizer.
Do you need to wear sunscreen in winter?
Yes, absolutely. Even when it's cold, even when it's snowing! In winter, the reflection off snow or light-colored surfaces amplifies UV rays , especially UVA rays, which are responsible for skin aging. A light SPF 30 is often enough, but don't skip this step in your routine.
The final word: protect your skin like a treasure 🌟
In short, asking “Should I wear sunscreen every day, even in the city?” is a bit like asking whether I should drink water even if I'm not sweating. The answer is a resounding YES.
