In this knowledge base it is treated as a cosmetic routine ingredient, not as a stand-alone medical treatment."]},{"heading":"Mechanism","paragraphs":["Sulfur supports the routine through properties that affect the outer skin surface. Depending on the ingredient, that may mean helping water bind in the stratum corneum, softening rough-feeling buildup, absorbing or reducing the look of excess oil, or making dry sensitive-feeling skin more comfortable.","The practical mechanism is formula-dependent. Concentration, vehicle, contact time, frequency, and the rest of the routine determine whether the ingredient feels helpful or irritating. That is why the page frames Sulfur as supportive skincare context rather than a guaranteed fix."]}],"side_effects":[{"title":"Over-exfoliation Irritation","url":"https://skinknowledgebase.com/side-effects/over-exfoliation-irritation"}]}
