Sunscreen is an essential part of any skincare regimen. Not only does it shield your skin from damaging ultraviolet (UV) rays, but it also helps prevent premature aging and reduces your risk of skin cancer.
How Sunscreen Works
Sunscreen works by absorbing or reflecting UV radiation. There are two types of UV radiation that can damage your skin:
UVA: These rays penetrate deep into the skin and can cause premature aging, wrinkles, and sunspots.
UVB: These rays mostly affect the surface of the skin and are the primary cause of sunburns.
Sunscreen contains either organic or mineral compounds that interact with and absorb UV radiation before it can penetrate your skin. Organic sunscreens contain chemicals like avobenzone or oxybenzone, while mineral sunscreens contain particles like zinc oxide or titanium dioxide that reflect UV radiation away from your skin.
Why You Should Wear Sunscreen Every Day
UV rays are present year-round, even on cloudy days. That means you should wear sunscreen every day, no matter the weather or season. Here are a few reasons why:
UV rays can penetrate glass, meaning you’re still at risk even if you’re indoors or in a car.
UV exposure is cumulative, meaning it adds up over time. This can result in premature aging, sunspots, and an increased risk of skin cancer.
Using sunscreen regularly can help prevent skin cancer, the most common cancer in the United States.
How to Choose the Right Sunscreen
Choosing the right sunscreen can feel overwhelming when faced with so many options. Here are a few tips:
Look for a broad-spectrum sunscreen that protects against both UVA and UVB rays.
Choose a sunscreen with an SPF (sun protection factor) of at least 30.
Consider your skin type. If you have sensitive skin, choose a mineral-based sunscreen. If you have oily skin, choose a lighter, non-greasy formula.
Don’t forget to reapply sunscreen every two hours, or more frequently if you’re swimming or sweating.
The bottom line is that wearing sunscreen every day is vital for your skin’s health. With so many options available, there’s no excuse not to protect your skin from harmful UV rays.
