Swimsuits with UPF 50+ fabric: Fact or fiction?


UPF stands for Ultraviolet Protection Factor. This is an indicator of garments that have been crafted using fabrics that are protective and prevent ultraviolet radiation from passing through to the skin.


Looking for this rating when buying a bikini or swimsuit is essential to protecting skin that has spent a lot of time exposed to the sun, either on the beach, at the pool, or meeting up friends on a terrace. Oftentimes we tend to think that just wearing a garment to cover our skin is enough to block out ultraviolet radiation, but the truth is that even using dark fabrics and polyester (which has been shown to prevent the impact of ultraviolet rays to a greater extent) is still not enough to protect the skin.


Because of this, here at TRESS we make all of our swimsuits and bikinis with UPF 50+ fabrics, the highest possible rating. Our goal is to protect your skin from ultraviolet rays in the areas where sunscreen doesn’t reach — providing protection both in and out of water.


When should we protect ourselves from the sun?


Have you ever heard someone say, “I don’t usually wear sunscreen” or “I only use sunscreen when I go to the beach”? In general, we tend to think that we are more prone to ultraviolet radiation when we’re exposed directly to it: when we do outdoor sports, when we go to the beach or sunbathe at the pool. But the truth is that these aren’t the only occasions when we should be protecting ourselves.


There are certain situations in our day to day lives that put our skin to the test. Meeting up with friends on a terrace, walking on the city’s pavement, shopping, walking to work — any of these, and other activities that involve exposing ourselves to the sun, can cause damage if we aren’t adequately prepared. That’s why it’s essential to wear UPF 50+ fabrics, in combination with sun cream every day.


Although skin blemishes are usually what most concerns us, sometimes we don’t take into account that skin has memory. All those times that we have burned our skin from sun exposure have made a dent on our skin’s memory. Our body somehow stores all of that information and manifests it in the form of blemishes, sunburns, premature wrinkles, and moles. This doesn’t mean that we should avoid sunbathing, but that we learn to protect our skin from the sun’s UVA and UVB rays.
