The age-old debate between bar soap and body wash has left many wondering: which one is actually better for your skin?
While both get the job done, the choice goes beyond personal preference. If you’ve ever asked, “Is bar soap or body wash better?”, the answer depends on your skin type, ingredient preferences, and sustainability values. Let’s break it down.
Ingredients: What’s Really Cleansing Your Skin?
One of the biggest differences between bar soap and body wash is the ingredient composition. Many conventional body washes contain surfactants like sodium lauryl sulfate (SLS), which create that luxurious lather but can strip the skin of its natural oils. This can leave your skin feeling tight and dry, especially if you have sensitive or dry skin.
On the other hand, high-quality bar soaps (especially those made with natural oils) use traditional saponification, a process that turns plant-based oils into gentle cleansers. Ingredients like shea butter, olive oil, and coconut oil help retain moisture while cleansing the skin. If you’ve ever felt like your skin needs a drink of water after using body wash, it could be due to synthetic detergents stripping away too much natural oil.
Science-backed insight: A study published in the Journal of Investigative Dermatology found that harsh surfactants in body wash can weaken the skin barrier, making it more prone to irritation and dryness.

Hygiene & Bacteria: Does Bar Soap Hold Germs?
A common myth is that bar soap harbors bacteria, making body wash the more hygienic option. However, research suggests otherwise. A study published in the Journal of Epidemiology and Infection found that while bacteria can be present on bar soap, it does not transfer to the skin in significant amounts to cause harm.
Bar soap actually cleans itself with every rinse, while body wash requires a loofah or sponge, which can trap moisture and bacteria if not cleaned properly. If hygiene is your concern, simply store your soap on a well-draining dish to keep it dry between uses.
Sustainability: The Environmental Impact of Your Shower Routine
If eco-friendliness is a priority, bar soap is the clear winner. Most body washes come in plastic bottles, contributing to waste and pollution. According to the Environmental Protection Agency (EPA), only about 9% of plastic waste is recycled, meaning the majority of body wash containers end up in landfills or oceans.
Bar soaps, especially those packaged in paper or cardboard, generate less waste and last longer than liquid body wash, making them the more sustainable choice.
📌 Fun fact: A study published in the American Journal of Chemical Engineering found that liquid soaps require five times more energy to produce and transport than solid soap bars.
Final Verdict: Is Bar Soap or Body Wash Better?
For those seeking gentle, nourishing ingredients and a more sustainable choice, bar soap is the clear winner. However, if you have extremely dry or sensitive skin, a soap bar with added humectants (like glycerin or hyaluronic acid) may work better in some cases.

I had a lot of issues with bacteria on my legs acne on the back of my thighs. This unhealthy skin. I tried using bar soap and after one day all the scarch issues that built up from infections in sporting accidents cleared up. The acne on the back of my legs. I’m a man that’s fairly hairy especially my legs. My doctor said that the brown patches that were appearing on my shins from old scars was not due to age but due to fungus. He said considered it a type of soap you use when you wash. Like all I use pump soap. It’s called for all brand sold at sprouts. I’ll never go back to liquid soaps at the bar. Soap leaves me feeling invigorated and truly cleaned. We’re thinking about some of the quote" men’s specific body. Washes were indeed harsh and did not clean as thoroughly. I have a feeling the LIE, the stuff that makes your eyes burn when you use a bar. Soap kills bacteria. I can’t explain the difference in my toenails and my fingers. My skin overalls younger and radiant. All because I switched to bar soap. I wish I’d never quit, but now there’s never been a larger selection of bar soaps for men to choose from. I like a brand called San Francisco soap company. Huge bars that last easily at 2 months and that’s with heavy use. Soaping myself up thoroughly washing behind my neck and washing behind my ears and it just strips out all the grit. Yet my skin is healthier. I saw that all my friends used pop soap the stuff from dispenser’s. I tried it when I was staying at their place and took liking to the convenience of the pump. Had no idea iusing chemicals rather than simple lye. If you have a skin condition, consider using a bar soap, even a heavily fragranced someone will make you a believer.
