Sunscreen is a product that is typically associated with sunny beach days, but it is important to understand that it should be used every day, no matter the weather or the season. In this article, we will discuss why sunscreen is not just for beach days anymore, its benefits, how to use it, and common myths associated with sunscreen.

Harmful Effects of UV Rays

UV rays are a type of electromagnetic radiation that come from the sun. There are two types of UV rays that reach the Earth’s surface: UVA and UVB rays. UVA rays penetrate deeper into the skin and can cause premature aging, while UVB rays cause sunburns. Both UVA and UVB rays can cause skin cancer.

Skin cancer is the most common type of cancer in the United States, with one in five Americans developing it in their lifetime. In fact, one person dies from melanoma, the deadliest form of skin cancer, every hour.

Sunscreen and Its Benefits

Sunscreen is a product that helps protect the skin from UV rays. It works by absorbing, reflecting, or scattering the UV rays that come in contact with the skin. There are two types of sunscreen: physical and chemical.

Physical sunscreens contain mineral-based ingredients such as zinc oxide or titanium dioxide, which create a physical barrier on the skin that reflects UV rays and Sunscreen Is Essential. Chemical sunscreens contain organic compounds that absorb UV rays and convert them into heat.

When choosing a sunscreen, it is important to consider the SPF (Sun Protection Factor) rating, which measures the amount of protection the sunscreen provides against UVB rays. It is recommended to use a sunscreen with an SPF of at least 30.

Tips for Using Sunscreen

It is important to apply sunscreen 15 to 30 minutes before going outside to allow it to fully absorb into the skin. It is also important to apply enough sunscreen to cover all exposed skin. A general rule of thumb is to use one ounce of sunscreen (about the size of a shot glass) for each application.

Sunscreen should be reapplied every two hours, or more frequently if swimming or sweating. It is also important to reapply sunscreen after toweling off or drying off after swimming.

Sunscreen Myths

There are many myths associated with sunscreen, such as higher SPF providing complete protection and that sunscreen can cause vitamin D deficiency. However, these are not true.

It is important to note that higher SPF ratings do not provide complete protection. SPF 30 blocks 97% of UVB rays, while SPF 50 blocks 98% of UVB rays. It is also important to note that sunscreen does not block all UV rays and that other methods of sun protection, such as wearing protective clothing and seeking shade, should also be used.

Additionally, while sunscreen can reduce the production of vitamin D, it is not the primary cause of vitamin D deficiency. Vitamin D can be obtained from foods and supplements.

The Importance of Wearing Sunscreen Daily

Sunscreen should be an essential part of everyone’s daily skincare routine. Even on cloudy days, UV rays can still penetrate the skin and cause damage. Applying sunscreen every day can help prevent premature aging, sunburns, and reduce the risk of skin cancer.

Other ways to protect the skin from UV rays include wearing protective clothing, such as long-sleeved shirts and hats, seeking shade, and avoiding peak hours of sun exposure.


In conclusion, sunscreen is not just for beach days anymore. It should be used every day, no matter the weather or the season, to protect the skin from harmful UV rays. Choosing the right sunscreen, applying it correctly, and understanding common myths associated with sunscreen are important steps to take in maintaining healthy skin.
