Do you need to apply sunscreen every day?

We often think of sunscreen when we picture hot summer days at the beach or pool.

The truth is that sunscreens are not only for special occasions. It should be part of your daily skincare routine no matter what the season or weather is.

UVA & UVB: Understanding Ultraviolet Rays

UVA & UVB UVA & UVB

UVA rays are the most common UV radiation to reach the Earth’s surface. These rays penetrate deeper and longer into the skin, damaging the deeper layers. UVA rays cause the skin to age prematurely, and they can also contribute to skin cancer.

UVB rays are longer, more energetic, and only penetrate the uppermost layers of the skin. These rays cause sunburns.

Both types of cancer can cause skin cancer.

How to Prevent Sunburns, Skin Cancer and Aging Signs

The majority of people know that sunscreen helps prevent sunburns. Although sunburns seem to be a minor inconvenience at first, they can cause serious damage. Sunburns cause blisters, pain, and swelling. They can also weaken your immune system.

Sunscreen is also helpful in preventing skin cancer. Sunscreen can protect you from skin cancer caused by UVA and UVB radiation.

Sunscreen can help to prevent the signs of aging, as well as protecting you from sunburns and cancer. Sun rays may cause wrinkles, age marks, and sagging of the skin.

Daily use of sunscreen can prevent the appearance of these signs and help keep your skin healthy and youthful.

When should you wear sunblock?

Wear sunscreen whenever you are exposed to direct sunlight. Wear sunscreen when you are hiking, swimming or playing sports.

Wearing sunscreen is essential, even on cloudy or rainy days. Clouds do block some sun rays but not all. Clouds are not impervious to UVA rays, which can cause skin damage.

Even if the weather is cold and snowy, it’s important to use sunscreen. Snow can reflect sun rays and make it more important to protect yourself.

Sitting near windows and long car rides can expose you to UV radiation. Apply sunscreen to all exposed skin when you are spending significant time in the vehicle or near windows.

Windows block UVB only. You won’t likely get a sunburn in a car or close to a window. You are still vulnerable to the carcinogenic UVA radiation, which can penetrate glass and damage skin cells.

According to clinical research, skin cancers are more common on the left side of the body – the side exposed most often to sunlight while driving.

You should also wear sunscreen if your skin is darker. You may not burn as easily, but you still risk developing skin cancer from excessive sun exposure.

Use a broad spectrum sunscreen to protect yourself against both types ultraviolet rays. Follow the directions on the label regarding the application and safety.
