Do Tan-Through Swimsuits Actually Work?

As summer approaches, many of us dream of achieving that perfect sun-kissed glow without the pesky tan lines. Enter tan-through swimsuits, a novel solution promising an even tan without the need for sunbathing in the buff. But do these swimsuits actually work? Let’s dive into the details.

What Are Tan-Through Swimsuits?

Tan-through swimsuits are made from a special fabric designed to let UV rays penetrate through the material, allowing you to tan underneath your swimsuit. This fabric typically consists of micro-perforations that are so small they maintain coverage and modesty while enabling sunlight to reach your skin.

How Do They Work?

The key to tan-through swimwear is the fabric’s unique weave. These fabrics are often lightweight and breathable, featuring thousands of tiny holes that allow about half of the sun’s rays to pass through. This technology ensures that UV rays can tan the skin under the swimsuit, potentially reducing the stark tan lines traditional swimwear can cause.

Do They Really Work?

For many users, the answer is yes, but with some caveats:

  • Gradual Tanning: Because tan-through fabrics let in only a portion of the sun’s rays, the tanning process is slower compared to tanning bare skin. This can be beneficial as it reduces the risk of sunburn.
  • Even Coverage: Proper fit is crucial. If the swimsuit shifts, you might still end up with some uneven tanning. 
  • Varied Effectiveness: The effectiveness can vary based on the brand and specific fabric used. Some users report excellent results, while others find the tanning effect minimal.

Additionally, these swimsuits tend to be more lightweight and may require careful handling to maintain their durability.


Tan-through swimsuits can be a useful tool for those looking to minimize tan lines, but they work best in combination with proper sun care practices. If you’re aiming for an even tan this summer, they’re certainly worth a try, with SWIMSARA swimwear we offer a 100 day hassle free return policy so there is no risk to trying!
