One thing to note is that the gloves feel pretty small and tight when you first put them on, but after the initial use, they do stretch out a bit and become more comfortable. G. Zhou, D.-W. Wang, F.

This loofah has two sides—one is very soft (softer than a washcloth), and the other is grittier. But despite the latter being rough enough to exfoliate the skin, the texture is very fine, so instead of irritating skin, it gently yet efficiently buffs away rough areas and makes skin feel super smooth. It lathers up just as well as body wash does on its own, if not a little bit better. On top of everything else, it can be thrown into the washing machine to clean, making it super hygienic and more environmentally friendly than loofahs that need to be tossed after a few weeks. While we were impressed with this device, it also fell short in a few ways. The heads felt too small (except for the massage head), so it took a while to use them over the entire body. It also felt awkward to use at times—the device has some give to it, so sometimes it was difficult to wrangle where we needed it to be. But, if you’re looking for something with all the bells and whistles, this is the option for you. C. K. Chan, H. L. Peng, G. Liu, K. McIlwrath, X. F. Zhang, R. A. Huggins and Y. Cui, Nat.

Wu, Carbon, 2011, 49, 1787 CrossRef CAS;While you may want loofah with serious physical exfoliating power to help slough off dead skin and promote circulation, a too-rough loofah can damage the skin. You want your loofah to have a soft, fine grit, explains Ross. “It shouldn’t be too rough, or it can break the skin, leading to irritation, redness, and possibly infection,” he tells Byrdie. Something like the Luv Scrub Mesh Body Exfoliator is ideal. K. S. Novoselov, A. K. Geim, S. V. Morozov, D. Jiang, Y. Zhang, S. V. Dubonos, I. V. Grigorieva and A. A.

It’s not the best option if you prefer a super sudsy shower, but the benefit to this is that it doesn’t soak up a lot of product, meaning less soap gets wasted. Overall, it’s a nice option for doing everything you need a loofah to do. It cleans well, mildly exfoliates, reaches everywhere on the body, and comes in five gorgeous colors. Plus, it’s long-lasting: The brand claims it’s good for up to 18 months. Loofahs can be made of various materials, including polyester, microfiber, cotton, nylon, silicone, mesh, or even natural sponges sourced from the ocean. The best options are long-lasting and resistant to bacteria and mildew growth. Last year, their trio of sustainable and reusable advent calendars was a huge hit, and this year, they're just as great (if not better). One of the best gift ideas 2022. This year's lineup is inspired by The Body Shop's Community Fair Trade programme, with each calendar celebrating the women who help produce the ingredients found in their products. Expect to indulge in the brand's best-selling goodies as well as new releases and even a few exclusives. Our personal favs include the Camomile Sumptuous Cleansing Butter, T ea Tree Face Wash, Himalayan Charcoal Purifying Glow Mask and the Vitamin E Hydrating Toner. Plus, you'll get a healthy mix of full-sized and travel-sized products – perfect to throw in your beauty bag for any upcoming holidays.

Out of all the loofahs we tested, this was our favorite. It was very effective at cleansing and exfoliating, it was able to reach the entire body, and it’s a hygienic, long-lasting option. This device also has bonuses built into nearly every feature. The loofah head is silver-infused, preventing it from harboring bacteria, and the silicone body and cleansing brush are naturally antibacterial, hypoallergenic, and odor resistant. The vibration—dubbed SonicGlow™ Technology—buzzes at 7,000 pulses a minute, which helps clear out pores and tone skin. There are four different settings, one low and one high, and two with a special vibrating pattern. However, when we used the vibration feature, it was a little uncomfortable to hold because we could feel the buzz throughout the handle instead of just concentrating at the end of the device. M.-H.

Beware that the low price means it may not be as high quality as other options. Some of us felt that the material was a bit rough. Still, it’s super affordable, and it’s made out of 100 percent recycled material. Overall, this is a great affordable loofah that exfoliates gently and without irritating skin. D. A. Dikin, S.

Tang, Phys. Chem. Chem. Phys., 2009, 11, 11101 RSC; To find the very best ones, we’ve done the so-called dirty work for you. After researching and choosing some of the most highly rated loofahs, we tested them all and used our usual body washes to accurately compare them to each other and our past loofah experiences and ultimately compile this list. The good news? None of these loofahs will irritate the skin, and better yet, they’ll help keep you clean and soft.

See DOI: 10.1039/c1ra00429h/ Crafted from a unique mesh-like wide-weave nylon, it effectively exfoliates the skin while still being gentle; it’s not scratchy or too rough for everyday use. “It feels like it gets a deep clean like I was scrubbing everything clean,” says tester Rachel Lee. “I was impressed with how effectively it exfoliated; my skin felt rejuvenated and so soft after. It noticeably helped with any skin texture/bumpiness!” Y.-S. He, D.-W. Bai, X. Yang, J. Chen, X.-Z. Liao and Z.-F. Ma, Electrochem.

It's not the best option for exfoliation, and the natural material may not last as long as synthetic loofahs. It could also use a hanging ribbon to make for easier use and to store while it dries. b) D. Wang, D. Choi, J. Li, Z. Yang, Z. Nie, R. Kou, D. Hu, C. Wang, L. V. Saraf, J. Zhang, I. A. Aksay and J.
