How Sulfur Helps Acne: A Scientific Look at the Mechanism of Action
Sulfur is one of the most time-tested active ingredients in dermatology — particularly in the treatment of acne vulgaris. But to understand how sulfur helps acne, we need to explore its biochemical actions and dermatological effects.
The Multi-Mechanism Action of Sulfur Against Acne
Keratolytic Action: Exfoliation at the Cellular Level
Sulfur promotes the desquamation (shedding) of the outer layer of the skin (stratum corneum) by breaking down keratin, a structural protein found in dead skin cells.
-
When keratin builds up excessively, it blocks pores and traps oil and bacteria.
-
Sulfur softens the keratin structure, helping clear clogged pores and preventing comedones (blackheads & whiteheads).
This keratolytic effect is similar to salicylic acid but gentler, making it suitable for sensitive or reactive skin types.
Sebostatic Properties: Oil-Absorbing Effect
Sulfur exhibits mild sebostatic activity, meaning it helps regulate sebum production on the skin. While it doesn't "shut down" oil glands completely (as isotretinoin does), it helps balance the skin’s oiliness — a key trigger for acne formation.
Combined with green clay or tea tree oil, sulfur can significantly reduce the greasy texture associated with acne-prone skin.
Antibacterial & Antimicrobial Action
Although sulfur is not an antibiotic, it alters the skin microbiome environment, making it less favorable for the growth of Cutibacterium acnes (C. acnes) — the bacteria involved in inflamed acne lesions.
-
Sulfur works by forming pentathionic acid and hydrogen sulfide when it comes into contact with the skin’s moisture.
-
These compounds exhibit mild antibacterial activity, which contributes to reducing redness, swelling, and post-inflammatory pigmentation.
Drying and Detoxifying
In concentrations between 3% and 10%, sulfur has a mild drying effect, which can:
-
Reduce pustules and papules
-
Minimize the presence of surface oil
-
Accelerate the healing of active acne breakouts
It also has adsorptive properties (especially when combined with clays), helping detoxify the skin by binding impurities and toxins.
