As the owner of Sienna Swim and someone who is always in a bikini, Sienna is constantly asked, “How is your bikini line so smooth?”

Like most of us, she used to rely on those little pink disposable razors and tried every razor on the market. Then she discovered her father's metal safety razor and had an epiphany – why don’t more women know about this incredible tool?

That’s when the idea of SMOOTH by Sienna Swim was born.

With nearly a year of thorough research, we’ve crafted the ultimate solution to achieve silky smooth skin. It’s sustainable and promotes your well-being, and will leave your skin flawless, free from pesky razor burn and ingrown hairs.

Unlock your best bikini season with Sienna Swim and SMOOTH.



A safety razor is the secret to the closest, smoothest shave possible, using just one double-edged blade instead of multiple blades like most disposable razors do. Crafted with the highest-quality metal, the weighty handle on our SMOOTH razor effortlessly glides over your skin. Not only does it outperform cartridge razors, but it also aids in reducing razor bumps and ingrown hairs.

Let's talk safety and sustainability. Metal razors are safer for you and the environment. Those supposedly “safe” lubricant or soap strips on plastic razors usually contain nasty chemicals like PFAs that can mess with our nervous and hormonal systems. Additionally, more than two billion plastic razors are tossed away annually, resulting in a million pounds of plastic waste, some of which ends up polluting our oceans. By choosing a metal razor, you're making an eco-friendly choice and stepping up your grooming routine — and it's more cost-effective too!

Using a safety razor is easy, as long as you approach it with patience and purpose. Prior to shaving, prepare your skin with a hot shower or bath to open up your  pores. Next, lather a generous amount of soap or cream onto the desired area and begin shaving with short, deliberate strokes at a 45-degree angle, just a few inches at a time. With the razor's weight doing most of the work, avoid applying excessive pressure like you would with a plastic razor. For the bikini zone, remember to shave along the hair's natural growth direction, keeping your skin taut for an effortlessly smooth glide. Rinse the blade frequently for optimal performance. There may be a slight learning curve when transitioning from traditional razors, but trust us—the benefits are absolutely worth it! Once you get the hang of it, you’ll never go back to plastic.

Absolutely! Our SMOOTH razor is perfect for shaving your armpits, legs, and bikini line. With its exceptional design, you'll experience a seamless shaving experience like no other.


Each SMOOTH by Sienna Swim razor comes with five of the highest-quality stainless steel blades. These double-sided blades offer up to eight shaves per side, which means you can enjoy up to 16 total shaves per blade. Depending on your shaving frequency, one blade could last you for many months! Say goodbye to constantly replacing your plastic razors and embrace the sustainable and economical choice of using a metal razor. Don't worry about running out of blades either, as purchasing an additional five-pack is easy and affordable. Our SMOOTH razor is truly the only razor you'll ever need!

With the proper care and maintenance, your SMOOTH razor can last for many years. Always remember to dry your SMOOTH razor after use and avoid storing it in the shower. Once a month, give it a gentle clean using castile soap, warm water, and an old toothbrush. By taking these precautions, your razor will continue to perform as well as the day you brought her home!
