Science
Mechanism of Action
Caprae Lac Extract acts through multiple pathways. Its natural lactic acid functions as a gentle alpha hydroxy acid (AHA), promoting cellular turnover by loosening bonds between dead skin cells, leading to a smoother and brighter skin surface. Beyond exfoliation, it delivers essential hydration and nourishment via a complex blend of vitamins (A, B, D, E), minerals (calcium, potassium), proteins, and fatty acids, helping the skin retain moisture. Proteins and fats within the extract provide soothing and anti-inflammatory benefits, calming irritation and reducing redness. Furthermore, fatty acids and lactic acid collaboratively strengthen the skin’s natural barrier function, enhancing protection against environmental stressors. The extract also contains antioxidants to combat environmental damage and proteins and vitamins that contribute to improved skin elasticity and firmness.

Key findings
- 01 Goat milk's natural lactic acid content provides gentle exfoliation by weakening bonds between dead skin cells, promoting a 28-day cellular turnover cycle, and strengthening the skin barrier through increased ceramide levels.
- 02 Topical application of lactic acid for one month significantly alleviated damage to the skin barrier caused by sodium lauryl sulfate, resulting in a 38% increase in ceramide levels in the stratum corneum.
- 03 A skincare product containing goat milk extract at this concentration range demonstrated continuous moisture, skin brightening, freckle removal, and anti-oxidative properties in consumer trials, with no feedback of anaphylaxis and proven suitability for all skin types.

Dusting Analysis
The Formula
Formulation
Stability
Goat milk is naturally pH-balanced, typically around 6.5, which closely matches the skin's natural pH. This intrinsic balance suggests good stability when formulated within a slightly acidic to neutral pH range. Mildly acidic conditions (pH 3-5) can also enhance the solubility of certain milk components, such as polyphenols, during the extraction process.
Conflicts
- Potential for Maillard reaction if formulated with ingredients containing primary or secondary amine groups, owing to the presence of reducing sugars (e.g., lactose) in milk.
Safety
Safety Profile
No specific CIR, SCCS, or FDA regulatory status for 'LAC EXTRACT' or 'CAPRAE LAC EXTRACT' has been found. While a product containing 8-10% goat milk extract showed no anaphylaxis in consumer trials, topical use of Caprae Lac can be allergenic for some individuals, particularly those with existing dairy allergies. The natural concentration of lactic acid (0.5-1%) in goat milk is generally considered safe for daily use.
