The most common side effect of African black soap is dry, tight or irritated skin. It usually comes from using too much, too often, or rubbing the rough bar straight on your face.1,2 The fix is simple: patch test first, start a few times a week, lather in your hands, and moisturize after.1 Below: every side effect and what to do, how to spot mold, and how long black soap lasts.

Quick answer

  • Dryness is the #1 complaint, especially with daily use on dry skin.2
  • Redness, rash, itching or burning: stop using it, or switch brands.1,2
  • Start 2 to 3 times a week, with a gentler cleanser on other days.1
  • Patch test a small area before your face.1,2
  • No expiry date? US law doesn't require one on cosmetics.3 Keep it dry between uses.

The short answer: it's safe for most people, but it can dry you out

African black soap is a West African soap. The raw bar we sell lists just palm oil, palm kernel oil and water; the paste lists palm oil, palm kernel oil and plantain leaves.4 Cleveland Clinic says side effects "depend on your skin type and any allergies or intolerances you may have," and that some soaps irritate people with eczema or people sensitive to dyes, fragrances, sulfur or cocoa.1

MedicineNet calls it "quite safe for almost all skin types," but notes that people with dry skin often complain of more dryness with daily use.2 So the side effects are real, mild for most people, and mostly avoidable.

Black soap side effects, and what to do about each

Dry, tight skinThe most common one, especially with daily use or dry skin.2What to doUse it less often, use less soap, and moisturize every time. Or pick a black soap with added shea butter.1,2
Redness or stingingYour skin is reacting to the soap or something in it.1What to doStop, let your skin calm down, then try another brand, or stop for good.1
Rash, itching or burningA sign this soap isn't for you.2What to doStop using it.2 If it doesn't settle, see a doctor or dermatologist.
Flare-ups with eczemaSome black soaps irritate eczema-prone skin.1What to doPatch test first, and choose a plain, unscented bar.1
Fragrance or cocoa reactionScented bars and cocoa butter versions can bother sensitive skin.1What to doRead the box. Dudu-Osun comes in scented versions; the raw bar has no fragrance on its label.4
Scratchy feelRaw black soap is rough and crumbly by nature.What to doDon't scrub the bar on your face. Lather it in your hands or on a washcloth, and massage in gently for about 90 seconds.1

How often should you use African black soap?

Cleveland Clinic suggests that you "may find it best to use this soap only two to three times a week, switching it up with a gentler cleanser on the other days."1 Here's a simple way to build up:

Week 1 to 2Patch test, then 2 to 3 times a week.1
No dryness?Add a day or two. Keep moisturizing.2
Every dayFine for some people. Back off at the first sign of tightness.2

Which black soap is gentlest? What the labels say

We read the boxes of the black soaps we sell in Chicago. "Black soap" covers very different products:

Soap From the label Fragrance? Good for
Manding Co. raw bar Palm oil, palm kernel oil and water None listed People who want the plain, traditional soap
Black soap paste 16 oz Palm oil, palm kernel oil, plantain leaves None listed Easy to scoop a small amount; no crumbly bar
Dudu-Osun Boxed bar sold as "Fresh" or "Classic" fragrance, "dermatologist-tested" Scented People who like a scented, smoother bar
Madina Shea & Aloe "100% vegetable base" with shea butter and aloe vera; the bar is pale green, not black Check box Dry skin: black soap with shea is what MedicineNet suggests2
Liquid black soap 8 oz Liquid body wash version Check bottle Body and shower use

Does African black soap mold or expire?

Expiry: many black soaps have no date on them. That's allowed: the FDA says "there are no U.S. laws or regulations that require cosmetics to have specific shelf lives or have expiration dates on their labels," and that working out shelf life is the maker's job.3 The FDA describes shelf life as how long a product will "look and act as expected and to stay safe for use."3

Mold: raw black soap is soft and soaks up water. A bar left sitting in a wet dish stays damp, and damp is where trouble starts. Throw it out if you see fuzzy growth, green or black spots that spread, or a sour or musty smell that wasn't there before. Uneven color and rough, dark flecks are normal in raw black soap; a fuzzy coat is not.

When in doubt, throw it out. A bar costs a few dollars. If a soap changes smell, color or feel, or starts to sting where it didn't before, replace it.

How to store black soap so it lasts

  1. Cut the bar. Break a big raw block into small pieces and use one at a time.
  2. Keep the rest wrapped in a closed container or zip bag, away from the shower.
  3. Use a draining soap dish so the piece you're using dries between washes.
  4. Scoop paste with dry, clean fingers or a spoon, and close the lid.
  5. Keep it cool and out of sun. Heat softens raw soap.
  6. Moisturize after washing. A little shea butter works well.2
