Science
Mechanism of Action
This ingredient functions as a potent 5-alpha reductase inhibitor, effectively down-regulating sebum production at its source. It maintains the skin's 'acid mantle' by acting as a bio-vector for glycine to keep pH levels within the optimal 4.5–5.5 range, while its amphiphilic structure allows it to disrupt the cellular membranes of acne-causing bacteria and Malassezia fungi.

Key findings
- 01 A 2% concentration demonstrated a statistically significant reduction in inflammatory acne lesions and overall skin clarity.
- 02 At a 5% concentration, research indicates measurable improvements in skin hydration and a visible reduction in the depth of fine lines.
- 03 A 4% inclusion, when paired with soy isoflavonoids, has been shown to clinically inhibit unwanted facial hair growth in female subjects.
Transparency
Dusting Analysis
While frequently used at trace amounts (under 0.5%) as a preservative booster or pH adjuster, clinical results for sebum control and acne reduction require a minimum threshold of 2.0%.
The Formula
Formulation
Stability
Highly stable due to its amphiphilic nature, making it versatile for both aqueous and anhydrous formulas. It is particularly effective for acidifying formulations to match the skin's natural barrier.
Synergies
- Soy isoflavonoids
- Surfactants
- Organic acids
Conflicts
- Alkaline environments above pH 7.0
Safety
Safety Profile
Deemed safe by the 2017 CIR Expert Panel. It is categorized as a non-sensitizer and is exceptionally rare as an irritant even in sensitive populations.
