Féret Parfumeur 'Bloc Hyalin' Alum Bloc 100g

The Féret Parfumeur Bloc Hyalin is a 100% natural potassium alum stone, renowned for its astringent, antiseptic, and antiperspirant properties. Sourced from Grade A+ Kalunite, this high-purity crystal is ideal for use as a natural deodorant, post-shave treatment, or to prevent chafing and friction during sport.

Unlike synthetic alternatives made with ammonium alum, the true Bloc Hyalin is slightly translucent and marbled, visibly distinguishing its authentic quality. Féret Parfumeur has been producing the original registered Bloc Hyalin since 1878, with a legacy protected by French law since 1899.

Apply to damp skin to leave an invisible, protective layer of microcrystals that help prevent bacteria and neutralise odour without blocking pores. Perfect for use after shaving to soothe razor burn, or before physical activity to keep feet and underarms dry.
