Osma Laboratoires Alum Block 75 g is an alum stone that prepares the skin before or after shaving.
Indeed, when shaving, the pores of the skin tend to open as a reaction to the razor passage. It is also the opportunity for certain bacteria to penetrate under the skin and trigger skin reactions (redness, ingrown hair...).
Thus, the alum stone will tighten pores in order to limit the irritation due to shaving and bacteria development as well as stop these annoyances.
