What does sulfur do in the formula and why is it used in skincare?

Sulfur is one of the oldest mineral ingredients used in skincare for oily and blemish-prone conditions, and its inclusion in this formula reflects a well-established functional tradition rather than a trend. It works as a natural antibacterial and antifungal agent that helps reduce the microorganisms on the skin’s surface that can contribute to blemish formation. Simultaneously, sulfur has a mild keratolytic effect, meaning it helps loosen and remove dead skin cells that can clog pores and create the conditions for breakouts to develop. It also helps reduce excess oil production on the skin’s surface, contributing to a more balanced and less congested appearance over time. When used regularly as part of a weekly masking routine, its cumulative oil-reducing and clarifying benefits become more noticeable as the skin adjusts to a more balanced state.
