The DermaHarmony 10% Benzoyl Peroxide (non-soap) Cleansing Bar was especially formulated for those with acne. This bar is for use on mild to moderate acne. It may be used in combination with other acne treatments as directed by your doctor. When applied to the skin, benzoyl peroxide (BPO) works by reducing the amount of acne-causing bacteria and by causing the skin to dry and peel. Benzoyl peroxide works well for inflammatory acne, which is characterized by red bumps that contain pus (pustules, papules, cysts, and nodules).  If you just have blackheads and whiteheads, salicylic acid & sulfur soaps and cleansers will work well to clear out pores. If you are prone to red, angry pimples then keep BPO in your product rotation.

At one point there were many BPO soap and cleaning bar brands. The market collapsed between 1995-2010 as washes and liquid cleansers became popular with millennials. These products are mostly water and inexpensive fillers.  BPO bars are making a comeback because they're better value and more eco-friendly.  Our BPO bar has a 'very hungry oil grabbing end' to the cleansing molecule. It's unique!


4 OZ (113 G) - 2.6" x 2.6" x 1" Square - Single Bar Per Box


For best results use daily. Work-up a lather using warm water and gently massage into problem areas. Cleansing solution should stay in contact with skin for at least 60-90 seconds. Then rinse thoroughly and pat dry. Use at least twice a week on affected areas in place of your regular soap or as directed by a doctor. If bothersome dryness or peeling occurs, reduce application to once a day or every other day. If desired, follow cleansing with the moisturizer of your choosing.


This product is not for use on broken skin or for internal use. In case of incidental ingestion, contact a physician or poison control center immediately. Rinse with water if solution comes into contact with eyes. 

BPO will bleach stain clothing and towels - use caution. It leaves funky orange stains on nearly everything it touches. Wash your hands well with soap and water after each application. Rinse your face and body extremely well before toweling off to prevent staining of fabrics.


10% Benzoyl Peroxide


Sodium Cocoyl Isethionate (SCI): Known as Baby Foam due to its exceptional mildness, SCI raw material is a surfactant that is comprised of a type of sulphonic acid called Isethionic Acid as well as the sodium salt ester from Coconut Oil.

Stearic Acid: A vegetable derived waxy substance used as a thickening agent in shampoo bars.

Coconut Fatty Acid: A surfactant, cleansing agent, emulsifier and a foam booster.

Sodium Isethionate: An organic salt isethionic acid that was discovered in 1833. It is used as an organosulfur compound. It lowers the pH while maintaining a high level of detergency and lather.


Coco Glucoside: A natural, gentle, and environmentally-friendly cleansing agent and surfactant (a word that is the shortened version of the term “Surface Active Agent”) sourced from coconuts. Sufactants prompt oil and water to combine, thereby making it easier for oily residue found on the hair to attach to syndet (synthetic detergent) and water, leaving the hair cleansed of any grease without stripping away its natural oils.

Cetearyl Alcohol & Ceteareth-20: Emulgade 1000 Ni by BASF - a vegetable based emulsifying wax.

Lactic Acid: An Alpha Hydroxy Acid or AHA used to gently exfoliate the skin, lighten dark spots, and improve the look of fine lines and wrinkles.

The 5% bar contains natural iron oxides which gives the bar an orange appearance (so that customers that use both the 10% and the 5% can differentiate between the bars). 

We DO NOT use these ingredients used by competitors:

We don't use Sodium Tallowate (a combination of tallow—a fat that is derived from the fatty tissue of horses, sheep, or cattle—and lye). 

We' don't use Ethylene/VA Copoloymer (a red-flagged micro-plastic).

We don't use Cocamidopropyl Betaine (a highly restricted surfactant with irritation and allergic contact dermatitis reactions and immunotoxicity concerns).


Store in a cool dry place between 59° - 86° F (15° - 30° C).  Benzoyl peroxide denatures at room temperature - it will begin to break down once exposed to air, heat, and moisture. Use within 12 months of purchase. Unopened product is good for two years from date of manufacture if bars have been stored in a controlled environment.


Stamped/embossed: "dermaharmony".

Sealed in recyclable polypropylene inside carton.

Carton ink is not petroleum-based which is better for recycling.

Goodbye sweat acne

I have been using this to help with my back and butt acne. I do crossfit daily and always get sweat acne around my sports bra. Once I started using this bar the acne cleared right away. Lathers nicely and does not overly dry my skin. I'm sensitive to fragrance and this bar has almost no smell. Love it.

My acne has improved significantly. It's almost gone. I'm using this BPO 10 bar in rotation with another dermaharmony zinc bar. Both active ingredients fight bacteria. I let this sit on my face for a two to three minutes and then rinse. The bars last me about 3 months.

Affordable, reliable acne treatment.

Ive been battling acne since I was 10 years old. Tried everything. Benzoyl peroxide is the only thing the ever worked for me. It's 'old school' and that's okay because it works for me. I highly reccomend this product to anyone serious about wanting to clear-up acne. Give it a try. Results vary, but you got to keep going until you find what works for you. For me, this is it!

Body Odor?

I bought this to use as an underarm soap after hearing a dermatologist recommend benzoyle peroxide for mitigating body odor bacteria. Suddenly my natural deoderant works! The bar has an ever-so-slight sulphur/medicinal scent, but it doesn't linger and I didn't notice it in the lather. I did notice that I didn't smell horrible later on in the day, which is a welcome change. Kinda life-changing, actually. I super appreciate the bar form for cutting down on plastic.

Clears acne

I may update my review when I've had the product longer, but so far, it seems to work about the same as my old BP cleanser in terms of clearing up my acne, but it doesn't feel as drying.

Acne eliminator

I have back/shoulder acne, and I've been using this for about a month now, and my skin has cleared up so much!! I've still got plenty of the bar left, so color me impressed!
