Mechanism of action:

➖Keratoplastic:

It slows down the epidermal cell proliferation by a cytostatic effect on the basal cell layer.

➖Anti-bacterial:

Sulfur is converted to hydrogen sulfide (H2S) through reduction, partly by bacteria. H2S has a lethal action on bacteria

➖Keratolytic:

Hydrogen sulfide and pentathionic acid are formed and cause damage to corneocytes and subsequent softening of the stratum corneum and shedding of cells.


✖️Contrary to popular belief, Sulfur is not a good degreasing agent (oil removing) , it is not as drying as other antiseborrheic agents.
