A Quick Overview of Sunscreen and Why It's So Important

In the summertime, one of the most important things you can do for your skin is to apply sunscreen. But what exactly is sunscreen, and why is it so important? Let's take a quick look at the science behind sunscreen and find out.

How Sunscreen Works

Sunscreen is a lotion, spray, gel, or other topical product that helps protect your skin from the sun's ultraviolet (UV) rays. The active ingredients in sunscreen work by either reflecting UV rays away from your skin or absorbing them into the sunscreen itself. This helps to prevent damage to your skin cells that can lead to skin cancer. It's important to remember that no sunscreen can completely block out all UV rays, so it's still important to take other precautions when spending time in the sun, such as wearing protective clothing or staying in the shade when possible.

The Different Types of Sunscreen

There are two main types of sunscreen: chemical and physical. Chemical sunscreens work by using active ingredients that absorb UV rays and turn them into heat, which is then released from your skin. Physical sunscreens work by using active ingredients that sit on top of your skin and deflect or scatter UV rays away from your body. Chemical sunscreens are typically more light-weight and easy to apply than physical sunscreens, but they may be more likely to irritate sensitive skin. Most sunscreens will contain a combination of both chemical and physical ingredients in order to provide the most effective protection possible.

Why You Should Use Sunscreen

In short, sunscreen helps protect your skin from damage that can lead to premature aging and skin cancer. According to the American Academy of Dermatology, Skin cancer is the most common cancer in the United States, with more than 5 million cases diagnosed each year. When caught early, skin cancer is highly treatable, which is why it's so important to perform regular self-exams and see a dermatologist regularly for professional exams as well.

In addition to protecting against skin cancer, sunscreen also helps prevent premature aging of the skin. Ultraviolet rays can cause fine lines & wrinkles, age spots, and dryness, so using a good sunscreen can help keep your skin looking its best.

As you can see, there are some clear benefits to using sunscreen on a regular basis. So make sure to slather on some SPF before heading out into the sunshine!
