Description

Traditional alum stone for aftershave care

The Alum Stone | Shaving Stone by Monsieur BARBIER is a classic of traditional shaving. This natural alum stone has astringent and soothing properties, helps relieve razor burn and can help stop bleeding more quickly from minor shaving cuts. As an aftershave stone, it is a simple, natural addition to wet shaving.

The monoblock alum stone is cut to shape directly from natural potassium alum – not reconstituted from powder. This gives it a smooth feel on the skin, prevents crumbling and allows it to wear down slowly. The hypoallergenic stone is suitable for all skin types, including sensitive skin.

💧 Soothing: Helps relieve razor burn and skin irritation after shaving.
🛡️ Astringent: Helps with minor shaving cuts and tightens the skin’s surface.
🌿 Natural: 100% natural monoblock without additives.
⚡ Long-lasting: Directly cut monoblock that does not crumble and wears down slowly.
✨ Traditional: An essential part of classic shaving routines for generations.

The Alum Stone | Shaving Stone combines traditional shaving care with exceptionally easy use – for skin that feels well cared for after shaving.

Active Ingredients

Potassium Alum (potassium alum):
Natural mineral salt with astringent, soothing and antibacterial properties.

How to Use

Moisten the stone with cold water.

Before electric shaving: Glide it over the skin to prepare the shave and lift the hairs.

After wet shaving: Slowly glide the wet stone over the shaved areas. On minor shaving nicks, its astringent action can help bleeding stop more quickly. Leave it on for a few seconds, then rinse the skin.

After use: Rinse the stone and allow it to air-dry completely. Do not put it back into its packaging while damp.

Ingredients

Frequently Asked Questions

Does a natural alum stone contain aluminium?

Yes. Potassium Alum is potassium aluminium sulfate and contains chemically bound aluminium. The stone must not be described as aluminium-free. It is a different compound from, for example, aluminium chlorohydrate.

Why can alum stone briefly sting after shaving?

On freshly shaved or irritated skin, or tiny shaving nicks, the astringent mineral salt may briefly tingle or sting. If a reaction is particularly uncomfortable or persists, stop using it and rinse the skin.

How is a solid monoblock alum stone different from pressed alum?

According to Monsieur BARBIER, this stone is cut to shape from a natural block of potassium alum rather than compressed from alum powder. The manufacturer highlights its smooth surface and low tendency to crumble.

Can I also use this alum stone as a deodorant?

Yes. Monsieur BARBIER mentions use on clean, damp underarm skin as a natural deodorant alternative. Rinse the stone after use and let it dry completely; take care on irritated skin.

Does alum stone replace a moisturizing aftershave balm?

No. Alum stone is mainly used after shaving for its astringent action and does not supply the moisture of a skincare balm. Once the stone has been rinsed off, an appropriate aftershave balm or face cream can be applied if needed.
