I Scoffed at Bar Soap Until I Found This Viral, Derm-Backed Formula

I need to admit, I have trust issues with "viral" products. Literally any product can become popular online, so I have to remind myself to be extra discerning before impulsively clicking "add to cart." During my most recent scroll, my algorithm must have known that winter skincare prep was on my mind, because the Tea Tree Oil Soap from RoyceDerm graced my feed more than once.

My interest was piqued, but I was skeptical. Not to sound judgmental, but I couldn't believe that many people were raving about bar soap. I did some more research just to be sure, and found even more users talking about it, but as a skincare snob, I needed a dermatologist's blessing before making this product a part of my routine.

And just like that, I found NYC-based derm Marisa Garshick, MD, FAAD. "I love the Tea Tree Oil Soap, as it is a great multitasker," she tells me. "It effectively cleanses and targets bacteria and fungus, while still being gentle on the skin."

You're probably familiar with the soap's hero ingredient, tea tree oil, which is known for its antibacterial and anti-inflammatory properties. However, you might be less familiar with clotrimazole—a hero ingredient that addresses all the unsexy skincare concerns we avoid talking about, like body odor, breakouts, and fungal rashes. And don't worry, it also contains hydrating ceramides and glycerin to keep your skin soft and your barrier protected throughout the winter season.

"I especially like that it can be used on the whole body, including the chest, back, and feet," Garshick says. "It can be used on all skin types, including those with sensitive skin." There you have it: All you need is a humble bar of soap to soothe your winter skin woes. Keep scrolling to check out more cold-weather skincare must-haves from this cult-favorite brand.
