The Importance of SPF: Why Sun Protection is a Must for Healthy Skin
When it comes to skincare, there’s one step that should never be skipped—no matter the weather, season, or your skin type—and that’s sunscreen. As an aesthetic nurse with a passion for skin health, I cannot stress enough how vital it is to protect your skin from the harmful effects of the sun. Proper sun protection is not just about preventing sunburns; it’s about maintaining youthful, healthy skin for the long term.
UV rays are a major cause of premature aging and a key factor in the development of wrinkles, dark spots, and loss of skin elasticity. As we age, our skin becomes more vulnerable to these damaging rays, and the effects can show up as fine lines, age spots, and increased skin sagging. This is why incorporating a broad-spectrum SPF into your daily skincare routine is one of the most important things you can do to protect your skin.
But why is SPF so crucial for your skin? UV radiation comes in two forms: UVA and UVB. UVA rays penetrate deeply into the skin and contribute to aging signs like wrinkles and fine lines, while UVB rays are responsible for causing sunburns and skin redness. Both types of rays can damage the skin at a cellular level and increase the risk of developing skin cancer over time.
Even if it's cloudy outside, UV rays can still reach your skin. In fact, up to 80% of UV rays can penetrate through clouds, meaning that you’re still at risk of sun damage—even on overcast days. This is why wearing SPF every day is essential, whether you're outdoors for an extended period or simply going about your daily routine.
The good news is that protecting your skin from the sun is easy!
Here’s how:
1. Choose a Broad-Spectrum Sunscreen
Look for a broad-spectrum sunscreen, meaning it protects against both UVA and UVB rays. The sunscreen should have an SPF of at least 30 for daily use, and if you’re spending extended time outdoors, go for a higher SPF of 50 or more.
2. Apply Generously
It’s not enough to just apply sunscreen once. You need to apply a generous layer to all exposed skin, including your face, neck, ears, and hands. Don't forget areas like the back of your neck and your chest if they're exposed to the sun.
3. Reapply Regularly
Sunscreen wears off after a few hours, so make sure to reapply it every two hours, especially if you’re swimming or sweating. For those who wear makeup, consider using a sunscreen setting spray or a powder SPF to touch up throughout the day.
4. Use Sunscreen Year-Round
Many people only think about sunscreen during the summer, but protecting your skin from UV damage is important year-round. The sun's rays can damage your skin in any season, whether it's hot and sunny or cold and snowy.
5. Don’t Rely on SPF Alone
While sunscreen is essential, it’s also helpful to seek shade during peak sun hours (typically 10 a.m. to 4 p.m.) and wear protective clothing like hats, sunglasses, and long sleeves when possible. These additional measures help reduce your risk of sun damage.
As a skincare professional, I’ve seen firsthand how a good skincare routine combined with consistent sun protection can transform the health and appearance of your skin. Not only will it help prevent signs of ageing, but it also significantly reduces your risk of skin cancer.
At There She Glows, I emphasise the importance of skin health in all my treatments. Whether you’re undergoing injectables or skincare therapies, protecting your skin from the sun is the first step in any regimen. A strong SPF routine ensures that your skin stays looking youthful and vibrant for years to come.
So, if you haven't already, now is the time to make sunscreen a part of your daily skincare routine. Your future self will thank you!
