Coal Spine

Materia Prima Soap N°1

Infused with active charcoal, an ode of nature's pure powers.

We love

Maras formulations are really invigorating and carefully thought out. While you are having your morning shower, you will not only have your skin feel cleansed with her carefully blended soaps, your senses will also be rewarded and you will be glad that you have to start your day smelling this good. We also love how it lingers in the bathroom and makes the whole space smell energetic and fresh for hours. It's a big wheel that will last a while. You you can gift it and use it just for your hands. Laters up nicely on a mitt or wash cloth. The paper packaging is 100% biodegradable. Check out Coal Spines other soaps we have in stock.

Step into the wilderness.
Crafted in France and infused with active charcoal, Moon Soap n°1 is a raw, sophisticated ritual—a deep detox that channels the wild, untamed spirit of nature. This is not just a cleanse; it’s a return to origin.

Perfectly balanced for all skin types—especially those in need of gentle, purifying care—this soap draws out impurities while enveloping the skin in a silken, mineral-rich lather.

The scent - A sensory journey.
Cool, invigorating top notes awaken the senses, followed by grounding, resinous woods and moss. Imagine stepping from a shadowy forest, wind-tousled and alive, skin kissed with the memory of earth and rain.

For face, hands, and body.
Suitable for all skin types, especially dry or delicate.
Perfume notes: warm, subtly spiced, ethereal—100% organic and natural.
No synthetics. No compromises.

COAL SPINE, founded by Mara Chevalier in 2016 and based in France, is a multidisciplinary studio that creates certified botanical cosmetics. The brand also delves into photography, art direction, and the development of creative concepts.

The name COAL SPINE reflects the brand’s ethos: "COAL" symbolises transformation under pressure, while "SPINE" stands for human strength and determination. This fusion embodies the courage to take risks and innovate.

Every product is handcrafted by Mara in the COAL SPINE studio, using responsibly sourced, certified organic botanicals and high-quality ingredients from Europe and abroad. The unique Moon Soap collection, a visual hallmark of the brand, is inspired by the moon's phases and draws upon the philosophies of Demeter, Carl Jung, and the alchemy of life and nature.

At COAL SPINE, every creation is crafted with care, ensuring that each plant used supports the skin’s natural processes. We design our botanical blends by carefully considering the active components and their synergistic effects when combined.

All products are handmade in small batches, following a meticulous, slow process that often takes a minimum of 8 weeks. We do not outsource any part of our production; everything is done in-house.

Our ingredients are responsibly sourced and of the highest quality. We use certified organic botanicals, oils, and clays from Europe and, when necessary, abroad. The chemical compounds used in our soaps are provided by certified laboratories that specialise in handling such ingredients.

As a European brand, our botanical oils and soaps contain essential oils within the strict limits set by EU regulations. This means we use only highly diluted concentrations to ensure safety and compliance.
