Who Should Wear UPF Clothing? A Guide to Sun-Protective Apparel

Applying sunscreen every day is an essential part of keeping skin safe from the sun’s ultraviolet (UV) radiation. However, wearing sunblock isn’t the only way to keep skin sun safe. There are also specialized clothing lines that create a protective barrier over skin. This protective apparel doesn’t have a sun protection factor like sunblock. Instead, it’s given an ultraviolet protection factor (UPF). According to Dr. Juan Estrada of U.S. Dermatology Partners Kyle, “UPF clothing provides continuous protection from sun damage without the need for reapplication. Instead, you can simply pull on a UPF clothing item and enjoy sun protection no matter how long you’re outside.” In this blog, Dr. Estrada answers the basic question, “What is UPF protection?” and reviews the benefits of wearing UPF apparel.

What Is UPF Protection and How Does It Work?

Ultraviolet protection factor (UPF) is a rating system that measures how effectively fabrics shield skin from ultraviolet radiation, which includes UVA and UVB rays. UPF protection products may be made with tightly woven fibers, specially treated fabric, or both to prevent UV rays from penetrating to skin. The UPF rating describes how much radiation reaches skin. Simply put, the higher the UPF rating, the more protection it provides. Although the numerical differences between these items of clothing seem small, the extra protection matters, especially during prolonged sun exposure or for individuals with a higher risk of skin cancer. To understand a UPF rating, consider the following examples:

• A UPF 50 garment blocks 98% of UV rays, allowing only 1/50th of the radiation to reach skin.
• A UPF 30 garment blocks 97% of UV rays, letting 1/30th of rays through.

UPF vs. SPF – What’s the Difference?

Many people are familiar with SPF (Sun Protection Factor). This is the designation given to sunscreen products to indicate their level of sun protection. Because UPF-rated clothing covers a broader UV spectrum and doesn’t require reapplication, it’s a powerful addition to your sun protection routine. However, it’s not a replacement for sunscreen but a complementary measure since UPF and SPF differ in significant ways. Below, we compare and contrast the sun protection features of SPF and UPF:

UPF 50 vs. UPF 30: Does It Matter?

When it comes to choosing a UPF rating, Dr. Estrada says, “The factors of protection become exponentially better when jumping from UPF 30 to UPF 50. Comparing UPF 50 vs UPF 30 shows that just that 20 point increase in UPF makes a big difference. UPF 30 blocks 97% of UV rays and UPF 50 blocks 98% of rays. That may seem like a negligible difference, but if you consider that the effects of sun damage are cumulative, that 1% difference really adds up. For prolonged sun exposure or those at high risk for skin cancer, choosing UPF 50+ clothing is worth the investment.”

Who Should Wear UPF Clothing?

UPF clothing is beneficial for everyone, but it’s particularly important for those at greater risk for sun damage. The following five groups of people benefit significantly from wearing UPF clothing:

1. Individuals with a Personal or Family History of Skin Cancer

Those who have been previously diagnosed with skin cancer or have close relatives who have been diagnosed with skin cancer are much more vulnerable to sun damage. UPF clothing provides an extra layer of consistent sun protection even if sunscreen wears off.

2. People with Fair Skin or Photosensitivity

Those with light complexions, especially if they have pale hair and eyes, are more likely to experience sun burns. Even one severe sunburn significantly increases risk for skin cancer. Sun protective clothing minimizes this risk. In addition to those with fair complexions, individuals with photosensitive skin, including those with lupus, polymorphous light eruption (PMLE), and porphyria, can experience significant skin damage with even small doses of harmful UV rays. They benefit significantly from wearing sun protective clothing.

3. Outdoor Workers

Individuals who work outdoors for long hours are at high risk for UV damage, and this damage accumulates over time. Landscapers, lifeguards, builders, and others benefit from investing in UPF clothing to reduce sun exposure as well as regulating temperature and wicking sweat away from the body.

4. Athletes

Many athletes spend significant amounts of time outdoors. Runners, golfers, cyclists, hikers, and other athletes end up outdoors for hours at a time. While exercising, sweat can wash off sunscreen, but UPF clothing provides consistent protection.

5. Children & Older Adults

Kids enjoy spending time outdoors, but their skin is more sensitive to sun damage compared with adults. Similarly, older adults have thinner skin that is more vulnerable to the sun’s damaging rays. Applying and reapplying sunscreen regularly can be difficult for children and older adults. UPF clothing offers continual protection that won’t irritate skin and doesn’t need to be reapplied.

When and How to Wear UPF Protective Clothing

UPF clothing isn’t just for the beach or summer months. Dr. Estrada says, “It’s important to protect skin from sun damage every day. Even when it’s overcast or chilly, UV rays penetrate clouds and bounce off surfaces like snow, water, and concrete. Whether you’re walking the dog, doing yard work, running errands, going to your kids’ sports events, or eating out with friends on the patio, wearing UPF clothing keeps skin safe from sun damage.”

While UPF clothing is beneficial, it’s still important to wear sunscreen every day. Keep the following tips in mind to maximize the benefits of UPF clothing:

• Start by applying broad-spectrum sunscreen with an SPF 30 or higher to all exposed areas of the body (hands, neck, face, ears, etc.).
• Then, put on UPF clothing that covers as much skin as possible while maintaining comfort.
• Wear hats to provide additional shade and protection for the face and neck.
• Protect eyes and the delicate skin around them with UV-blocking sunglasses.
• Seek Shade during peak sun hours (10 a, to 4 pm).
• Avoid Tanning Beds that emit harmful UV radiation.

Pairing UPF with Physical Sunscreen

In addition to wearing UPF sun protective closing, Dr. Estrada emphasizes the importance of choosing the right sunscreen for optimal protection. “When it comes to sunscreen, we recommend physical sunblock that includes ingredients like zinc oxide or titanium dioxide,” Dr. Estrada explains. “These mineral-based ingredients sit on top of the skin and reflect UV rays like a shield. They’re especially great for sensitive skin and less likely to cause irritation. For the best defense against sun damage, combine daily use of physical sunscreen with UPF-rated clothing, and don’t forget to reapply every two hours when you’re outdoors.”
