How to

Run the block under warm water and rub it on to your face. The alum will be quickly sooth any irritation and razor burn. Smoothed onto the skin it leaves an invisible film of mineral salt which reduces perspiration.

For longer life, use the drip tray provided and never let your block remain in prolonged contact with water. When properly cared for, your BLOC HYALIN alum stone will last for years.


For after shaving, waxing or as a natural deodorant.

Multiple alum stone properties have been known since ancient times: softening, moisturizing, astringent, cauterizing, anti-bacterial, non-allergenic and deodorant.

Used a deodorant, BLOC HYALIN is totally odorless, and will leave your clothes unmarked. Unlike conventional deodorant that often simply masks odors, it remains on the surface of the skin and forms an invisible protective film of mineral salts which prevents the formation of bacteria that causes body odor. BLOC HYALIN does not block pores, allowing the skin to breathe normally, and simply prevents odors from forming, ensuring safe and natural freshness.

Waxing and depilation: BLOC HYALIN oothes razor, waxing or depilation rash. In addition, regular use can help to reduce the appearance of ingrown hairs.

Shaving: Used before shaving, the astringent properties of BLOC HYALIN prepare the hair and make shaving easier. Used after shaving, it soothes razor rash, tones the skin and leaves a real sensation of freshness. Its anti-bacterial property prevents the appearance of spots and in the case of a cut, prevents bleeding.

BLOC HYALIN should be kept dry in its box or in a soap holder.
