Monsieur BARBIER PIERRE D'ALUN – Natural Aftershave Stone 75g

A traditional shaving essential for calmer, smoother-feeling skin.

PIERRE D'ALUN by Monsieur BARBIER is a 100% natural alum stone, traditionally used by barbers for its soothing and astringent properties.

After shaving, the stone helps calm the feeling of razor burn and supports the skin after shaving. It can also be used before an electric shave to help prepare the skin and lift the hairs for easier shaving.

Unlike reconstructed alum blocks, Monsieur BARBIER's stone is cut directly from a natural block, giving it excellent durability without crumbling.

A simple, long-lasting addition to a traditional shaving routine.
