Science
Mechanism of Action
LAC POWDER functions primarily as a skin conditioning agent. Its natural composition of casein, lactose, and lactic acid contributes to gentle exfoliation, facilitating the removal of dead skin cells, while simultaneously delivering hydration to promote skin softness. This multi-faceted action aids in maintaining skin in good condition and may enhance its resilience against environmental stressors.

Key findings
- 01 The lactic acid component within cow's milk powder is recognized for its exfoliating properties; concentrations of lactic acid between 2-5% are considered suitable for regular use, although they may cause irritation in sensitive skin. Separately, encapsulated bovine colostrum, a related milk-derived ingredient, has been successfully integrated into various powder-based facial mask formulations at concentrations ranging from 20% to 50%, with further research required to establish its efficacy.

Stability
To preserve its potency, LAC POWDER requires storage in cool, dry conditions, away from direct sunlight and humidity. It must be kept in sealed, airtight containers, and handling with clean, dry utensils is critical to prevent microbial contamination.
Safety
Safety Profile
LAC POWDER is generally considered a safe cosmetic ingredient, with low concerns regarding carcinogenicity, allergies & immunotoxicity, and developmental or reproductive toxicity. It is not featured on EWG's restricted lists. However, individuals with dairy sensitivities may experience skin irritation. While not specifically reviewed by CIR or SCCS for cosmetic applications, related products like cow's milk powder for infant formula have been subject to FDA recalls due to nutrient deficiencies, which are unrelated to cosmetic safety.
