Féret Bloc Hyalin: Authentic Quality!

You can recognize the authentic Bloc Hyalin by its slightly translucent, marble-like appearance and the mention of potassium alum in the list of ingredients. Unlike synthetic alum stones (ammonium alum), which appear opaque, the true Bloc Hyalin stands out with its superior visual quality and natural transparency.

Féret Hyaline Bloc, loved for its natural astringent and antiperspirant properties, and trusted for over a century. Made in France, it blends tradition with exceptional craftsmanship.

Astringent Properties: Helps tighten the skin and reduce perspiration while remaining gentle and effective.

Antiperspirant Action: Forms a thin, transparent film that regulates surface perspiration without clogging pores. It eliminates bacteria, the main cause of unpleasant odors.

Natural Deodorant: Prevents bad odors by creating a protective barrier against bacterial growth.

Ideal for Athletes: Reduces chafing and prevents injuries caused by friction. Apply it to your hands, feet, or other areas before putting on gloves, socks, or shoes to keep your skin dry.

Perfect Post-Shave Solution: Stops bleeding from minor cuts caused by shaving and minimizes the appearance of razor bumps.

How to Use the Bloc Hyalin Daily:
The Bloc Hyalin is presented in its raw form, with a hand-rounded and polished tip for smooth and comfortable application. Simply moisten the stone with warm water and glide it over the desired areas.

Once applied, the stone leaves an invisible layer of thousands of micro-crystals on the skin. This natural barrier prevents the growth of odor-causing bacteria, ensuring you stay fresh and protected throughout the day.
