Science
Mechanism of Action
Creates a non-greasy occlusive barrier that prevents transepidermal water loss while its lactic acid ester structure provides mild keratolytic action by loosening corneocyte adhesion. Additionally functions as an anti-irritant in surfactant systems and enhances penetration of lipophilic actives through improved follicular delivery.

Key findings
- 01 At 1.0% concentration, significantly reduced skin irritation from benzoyl peroxide while enhancing follicular penetration (Johnson & Johnson patent data)
- 02 24-month safety study at 5-10% showed excellent tolerability with only 7.9% experiencing mild erythema (FDA Clinical Review NDA 203567)
- 03 48-hour patch testing demonstrated non-irritating profile with zero sensitization potential in 50 subjects (CIR Expert Panel 2010)
