5 Sun protection myths debunked: What you need to now
Jun 13, 2024
Spending time in the sun is often associated with joy, vitality, and unforgettable moments outdoors. But the sun, while essential to life, also brings invisible risks, especially when it comes to UV exposure. At Juillet Juillet, where we design UPF 50+ swimwear that protects the whole family, we often hear the same misconceptions come up again and again. These myths, while persistent, can lead to poor habits that compromise your skin’s health.
So let’s take a moment to break things down. In this article, we’ll dive into five of the most common sun protection myths and unpack the facts behind them. Whether you're already an advocate for anti-UV swimwear or just beginning to explore what UPF 50+ means, this guide will give you the tools to protect your skin with confidence.
Myth 1: a tan equals protection
There’s a long-standing belief that getting a “base tan” at the beginning of summer can help prevent sunburn later. Some even consider it a form of natural protection. Unfortunately, that assumption couldn’t be more wrong.
In reality, a tan is the skin's stress response to damage. When your skin cells are exposed to ultraviolet rays, they produce more melanin in an effort to protect deeper layers. That increase in pigment is what we see as tanning—but it’s actually a sign that the DNA in your skin cells has already been harmed. This damage accumulates over time and contributes to premature aging, wrinkles, and, more seriously, an increased risk of skin cancer.
From a purely numerical standpoint, even a deep tan offers protection equivalent to an SPF of about 3 or 4. Compare that to the recommended minimum of SPF 30, and it becomes clear that tanning is no substitute for proper protection.
If you're looking to enjoy the sun safely, opt for UPF 50+ swimwear that offers consistent, full coverage, especially during peak sunlight hours. Our long sleeve maillots de bain are designed to do exactly that—protect your skin, without compromising on elegance.
Myth 2: sunscreen is only needed on sunny days
This one is particularly dangerous because it sounds reasonable. If the sun is hiding behind clouds, why bother with sunscreen? But the truth is, up to 80% of UV rays still reach the earth on cloudy or overcast days. In fact, because the rays scatter, they can even be more unpredictable and reach the skin from multiple angles.
UV rays are also reflected by surfaces like sand, snow, water, and even concrete. That means you’re often getting exposure from above and below, especially at the beach.
So whether you're headed to the mountains, going for a city walk, or taking the kids to the sea, daily sun protection is non negotiable. For maximum effectiveness, we recommend combining broad-spectrum sunscreen with anti-UV swimwear, which helps reduce the need for constant reapplication.
At Juillet Juillet, our UPF 50+ bikini sets are ideal for active days outdoors, offering coverage where it matters most with breathable, elegant designs.
Myth 3: high SPF means all-day protection
This myth is easy to believe. Many consumers think that using a high-SPF sunscreen (like SPF 50 or more) gives them full-day coverage. It feels like a logical shortcut: the higher the number, the longer the protection, right?
Not quite. SPF (Sun Protection Factor) measures how long UVB rays take to redden your skin compared to bare skin. But it doesn't mean your sunscreen lasts longer or doesn’t need to be reapplied.
In reality, even the most resistant formulas break down with sweat, water, friction, and time. Most dermatologists agree: sunscreen should be reapplied at least every two hours, and more often if you're swimming or sweating.
And another common mistake? Applying sunscreen right before exposure. Chemical sunscreens in particular need about 15 to 20 minutes to become effective, so always plan ahead. If you’re getting the kids ready for the beach, make sunscreen part of the routine before you even leave the house.
Of course, no sunscreen is perfect. That’s why the most effective strategy is layering protection: a mineral sunscreen for exposed areas and UPF 50+ maillots de bain to reduce the need for constant reapplication. The Juillet Juillet women's collection offers beautiful, sun-safe alternatives that simplify your skincare routine while enhancing your beach style.
Myth 4: people with dark skin don’t need sun protection
Melanin, the pigment that gives skin its color, does offer some natural protection from UV rays. But this protection is not complete, and it's certainly not a reason to skip sun protection altogether.
People with darker skin tones can still experience sunburn, photoaging, and are absolutely at risk for skin cancer, including the dangerous melanoma type. In fact, because of widespread misconceptions, skin cancer is often diagnosed later in people with darker complexions, making outcomes worse.
The truth is: everyone needs sun protection, regardless of skin tone. This includes daily sunscreen on exposed areas and the use of UPF-rated clothing for outdoor activities. At Juillet Juillet, our kids’ anti-UV swimwear is designed to suit every skin tone and body type, with prints and cuts that kids love to wear.
Myth 5: sunscreen makes UV-protective clothing unnecessary
You might think that if you’ve applied sunscreen generously, UV-protective clothing is redundant. But consider how easy it is to miss spots, especially on squirmy children, or how often sunscreen wears off during a swim or a beach game.
UPF 50+ clothing acts as a reliable, constant shield, particularly on areas like the shoulders, chest, and back, which are most exposed and most often forgotten. It also eliminates the need for reapplication on covered areas, making your beach day easier and more carefree.
Our UPF 50+ one-piece swimsuits for women are crafted to blend comfort, design, and effective coverage, making them a smart choice for long days in the sun.
How to build a truly effective sun protection routine
Now that we've dispelled these myths, let’s recap what truly works. A complete sun protection strategy doesn’t rely on a single product or habit, it’s a combination of smart choices:
-
Apply a broad-spectrum sunscreen daily, regardless of weather
-
Reapply every two hours, or more often after water or sweat
-
Wear UPF 50+ swimwear to protect large surface areas without relying solely on sunscreen
-
Choose accessories like wide-brim hats and UV-protective sunglasses
-
Plan outdoor activities outside peak UV hours whenever possible
-
Use portable shade solutions, especially for young children
