An ergonomic, hand-shaped pebble
Our organic pebble-shaped soaps are handcrafted in small batches in our workshop in Provence. Each piece is designed to become part of your skincare ritual: compact, rounded, and elegant. Its shape invites a natural gesture — the palm gliding smoothly over the skin.
Made with certified organic plant-based ingredients, and free from plastic or compromise, they gently cleanse while respecting the skin’s natural balance.
Embrace a format that combines simplicity, effectiveness, and aesthetics — a more mindful approach to beauty, attentive to detail, to yourself, and to the planet.

What is a pebble soap?
A pebble soap is a solid soap shaped like a river pebble: rounded, edgeless, small enough to sit in the palm of your hand. At Sternartica each pebble weighs 90 g, nearly as much as a classic bar: it is the same cold-process, superfatted and organic paste, poured and unmoulded by hand in my workshop in Drôme Provençale. The shape changes, and the gesture with it: the travel pouch, the guest bathroom, the small gift that does not look like a bar of soap.
Why the pebble shape changes the gesture
It sits in the hand
No corner that crumbles, no bar that slips away. Your palm follows the curve and the shower gesture becomes softer.
It dries quickly
No flat face stuck to the holder: the pebble drains on every side and dries between two showers, as long as it stays out of the water jet.
It travels
No bottle, no liquid, nothing to declare in the cabin. One pebble in its case and your toiletry bag really does get lighter.
Our 5 pebble soaps
The five pebbles use the formulas of my five 100 g bars. Same soap paste, same cold process, same four to eight week cure: 90 g instead of 100, and a rounded shape. Choose by skin type first.
Clair de Lune
Sensitive skin, babies
No fragrance, no essential oils, no declared allergens. Organic shea butter and oat.

How to make a pebble soap last
- Wet the pebble and glide it straight over the skin, or work up the lather between your hands.
- Rinse the pebble after use: leftover lather is what eats it away fastest.
- Set it away from the shower stream, on a holder that lets the water drain.
- If your bathroom stays damp, a magnetic soap holder keeps it suspended so it dries on every side.

Founder, Sternartica
The pebbles are the same soap paste as my 100 g bars, poured into a rounded mould. 90 g instead of 100, and a shape that sits in the palm. I make them in small batches in my workshop in Drôme Provençale and wrap them one by one in FSC-certified paper printed in France. It is the format I most like to give: it fits in a pocket, it cannot spill, and you can see at once what is inside.
