Sunscreen Myths and Facts

As summer approaches, it’s essential to understand the importance of sun protection and the role of sunscreen in maintaining healthy skin. Despite the wealth of information available, many myths and misconceptions persist about sunscreen. This article aims to debunk these myths and provide accurate, comprehensive information on sunscreen usage, benefits, and potential risks.

Guide to Sun Protection - Sunscreen Myths and Facts

Myth 1: Sunscreen causes cancer

False. There is no medical evidence that sunscreen causes cancer. In fact, sunscreen helps protect your skin from harmful UV rays, which are known to cause skin cancer. For those concerned about chemicals in sunscreens, using a sunblock with physical barriers like zinc oxide and titanium dioxide is recommended.

Myth 2: Higher SPF provides significantly more protection

Not necessarily. While higher SPF sunscreens do provide more protection, the difference is not as significant as one might think. The FDA has proposed a cap of SPF 60+, and it is recommended to avoid sunscreens with SPF over 50+.

Myth 3: Vitamin A in sunscreen is beneficial

Contrary to popular belief, vitamin A may accelerate skin tumor and lesion growth when exposed to sunlight and should be avoided in sun-exposed skin.

Myth 4: Sunscreen causes vitamin D deficiency

Sun protection is essential for everyone, regardless of skin tone. While it is true that sun exposure helps the body produce vitamin D, excessive sun exposure can lead to skin damage and increase the risk of skin cancer. It is crucial to strike a balance between sun protection and vitamin D production.

Myth 5: All clothing blocks the sun’s rays

Not all clothing provides adequate sun protection. It is essential to choose clothing with a high ultraviolet protection factor (UPF) to ensure sufficient protection from the sun’s harmful rays.

How to choose and apply sunscreen

When selecting a sunscreen, look for a product with an SPF of 30 or higher, water resistance, and broad-spectrum coverage (protection from both UVA and UVB rays). Apply sunscreen liberally to all uncovered skin, including the nose, ears, neck, hands, feet, and lips, and reapply at least every two hours or more often if swimming or sweating. It is also essential to apply sunscreen 15 minutes before going outdoors, as it takes time for the skin to absorb the sunscreen and provide protection.


Sunscreen plays a vital role in protecting our skin from the harmful effects of the sun. By debunking common myths and misconceptions, we can make informed decisions about sun protection and enjoy the summer months safely. Remember to choose the right sunscreen, apply it correctly, and combine it with other sun protection measures such as wearing protective clothing, seeking shade, and wearing sunglasses.
