Beldi Black Soap (Savon Noir): Benefits and How It's Made

What it is

Beldi black soap — savon noir, sabon beldi — is a soft, dark-brown paste made from black olives and olive oil, macerated in salt and potash (a plant-based alkali). It has been made in Morocco for centuries and contains no perfume, no colour and no synthetic surfactants in its traditional form.

What it does for the skin

• Prepares the skin for exfoliation. Left on for 5–10 minutes in the steam, it softens the outer layer so dead skin lifts away easily.
• Cleanses gently. It removes dirt and excess oil without the tight, stripped feeling of a harsh soap.
• Nourishes. Olive oil brings vitamin E and antioxidants; skin feels supple afterwards.
• Suits most skin types, including sensitive skin, because the pH is mild and the ingredient list is short.

How to use it

On damp, warm skin, spread a thin layer over the whole body (avoid the face if your skin is very reactive). Wait in the heat for 5–10 minutes — do not let it dry out. Then scrub with a kessa glove and rinse well. Once or twice a week is plenty; over-exfoliating irritates the skin barrier.

Buying and keeping it

Look for a plain paste whose label lists little more than Olea europaea (olive) and potassium hydroxide. It keeps for months in a sealed jar at room temperature. A eucalyptus-scented version is common and pleasant, but the unscented one is the safest for sensitive skin. In our hammam ritual, the black soap is always included — and you leave with a bar to continue at home.
