Science
Mechanism of Action
This stable vitamin C derivative effectively penetrates the skin where it is enzymatically hydrolyzed by lactase into bioactive ascorbic acid. Functioning as a potent antioxidant, it actively neutralizes free radicals, thereby shielding skin cells from oxidative stress and mitigating premature aging. Additionally, Ascorbyl Lactoside significantly promotes the synthesis of new collagen and demonstrates a pronounced skin brightening effect through direct inhibition of tyrosinase bioactivity and reduction of melanin accumulation.

Dusting Analysis
The research provides precise in vitro concentration data (0.05% for IC50 and 0.25% for 80% inhibition) demonstrating significant efficacy in tyrosinase suppression. These specific, effective concentrations suggest that Ascorbyl Lactoside is not typically included at ineffective 'dusting' levels, but rather at functional percentages.
The Formula
Formulation
Stability
Ascorbyl Lactoside exhibits superior stability compared to other ascorbic acid derivatives, including ascorbyl glucoside. It is notably tolerant to high temperatures and metal ions within formulations, and maintains its activity across a wide pH range. It demonstrates robust stability against oxidation, retaining over 85% of its original content after 48 hours in stability tests.
Safety
Safety Profile
Ascorbyl Lactoside is considered safe, showing no adverse impact or irritation potential when compared to classic cosmetic ingredients. In in vitro experiments, it exhibited the lowest cytotoxicity among competitive ingredients such as ascorbyl glucoside, kojic acid, and arbutin.
