Celebrities like Nicole Kidman and Anne Hathaway are increasingly hitting the beach in full coverage, sun protective swimwear. Whether or not anti-ageing, pale skin, or health concerns are the motivation for donning a long-sleeve one-piece, the truth is: UPF50 swimwear is just good for your skin.
Australians tend to understand that actual sun safety goes beyond a film of sunscreen and a cute hat. It’s surprising then that women aren’t embracing UPF swimwear—especially with increasingly stylish options available.
“UPF swimwear is one of the easiest and most reliable ways to protect our skin from UV damage, which contributes to both skin cancer and premature skin ageing,” explains Queensland-based dermatologist, Dr Leona Yip.
“Unlike sunscreen, which needs regular reapplication, protective swimwear provides a physical barrier over the skin it covers. And let’s face it, most of us aren’t particularly diligent about reapplying sunscreen every two hours, especially when we’re outdoors for prolonged periods.”

Once upon a time, ‘rashies’—i.e. long-sleeved swim shirts—were not considered the pinnacle of beach style for adult women. However, whether it’s the celebrity endorsements (thank you, Nic) or a growing emphasis on sun protection, we’re re-evaluating this vital swimsuit design.

To my surprise, plenty of stylish swimwear brands are now using UPF50 fabrics in their construction. While long-sleeve swimwear is important for the best sun protection, you can also improve the UV-protective quality of your regular swimsuit by shopping from a brand that uses UPF materials. Now, for the important questions…
What Is UPF Swimwear?
UPF stands for Ultraviolet Protection Factor, and it’s the measure of how well fabrics block UV rays. Where the term SPF (Sun Protection Factor) is applied to sunscreen, UPF is applied to textiles.
UPF is evaluated in regard to the tightness of the weave and how much UV light can physically get through the fabric, fibre composition and its UV reflective capabilities, and other treatments in the dying and manufacturing process that can help in blocking UV rays.
Is There A Difference Between UV-Protective and UPF50+ Swimwear?
Yes, there is a difference between claims of ‘UV Protection’ and ‘UPF50+ Swimwear’. “It’s an important distinction,” Dr Yip says. “‘UV-protective’ is a broad description, whereas UPF50+ is a specific, tested rating indicating that the fabric blocks at least 98% of UV radiation under standard test conditions.
“Think of UPF as the clothing equivalent of SPF in sunscreen. The higher the rating, the greater the UV protection. I would recommend looking for UPF50+ rather than relying on vague marketing claims about UV protection.”
What To Look For In UPF50+ Swimwear
Dr Yip recommends looking beyond the UPF factor, and considering coverage as well. “Long sleeves, higher necklines and designs that cover more skin provide better overall protection. A UPF50+ bikini might have excellent fabric protection, but it’s not doing much for the skin it doesn’t cover!” she explains.
“Look for a comfortable fit that doesn’t overstretch the fabric, as stretching can reduce UV protection,” Dr Yip adds. “Also consider whether the material maintains its protection when wet, as not all fabrics perform equally in water.”
Finally, Dr Yip reminds that UPF swimwear does not replace sunscreen, a hat, sunglasses and seeking shade for effective sun protection.
