Science
Mechanism of Action
This ingredient utilizes natural lactic acid to promote mild cellular turnover without disrupting the skin's acidic mantle. Its high lipid content—specifically caprylic and capric acids—repairs the cutaneous barrier, while a cocktail of vitamins (A, B6, B12, C, D, E) and minerals like selenium provides antioxidant support and deep nourishment at a physiological pH of 6.4.

Key findings
- 01 A 5% clinical-grade formulation demonstrated a 2x increase in skin hydration and a 90x improvement in omega fatty acid delivery to the barrier.
- 02 A 14-day perception study using a 100% concentration equivalent resulted in 100% of participants reporting immediate moisture and improved skin health.
- 03 Safety assessments at 20.84% confirmed the ingredient's high margin of safety and lack of systemic toxicity.
Transparency
Dusting Analysis
Caprae Lac is frequently included at very low percentages (<1%) in mass-market soaps and lotions for marketing appeal. Clinical data suggests a minimum of 5% is required to achieve measurable increases in barrier fatty acid delivery and significant hydration.
The Formula
Formulation
Stability
Highly thermolabile; proteins denature if exposed to temperatures exceeding 40-50°C. Powder forms are hygroscopic and require specialized storage to prevent clumping.
Synergies
- Ceramides
- Glycerin
- Niacinamide
Conflicts
- Temperatures >50°C
- Strong mineral acids (causes curdling)
- Strong oxidizing agents
