Science
Mechanism of Action
Prunus Mume Bud Extract operates through multiple pathways to enhance dermal integrity and appearance. It functions as a robust antioxidant, effectively neutralizing harmful free radicals to mitigate oxidative damage. The extract actively inhibits melanin synthesis by regulating melanogenesis-associated protein expression, contributing to a visible skin-brightening effect. Furthermore, it safeguards skin structural proteins against glycation and the formation of Advanced Glycation End-products (AGEs), while promoting collagen production. Its capacity to enhance aquaporin-3 (AQP3) expression in keratinocytes facilitates optimal hydration, simultaneously reinforcing the skin’s protective barrier against environmental aggressors and supporting cellular regeneration, particularly against UV-induced damage.

Key findings
- 01 Demonstrated significant antioxidant activity, neutralizing over 45% of free radical activity at a 0.1% concentration in vitro (Prunus mume extract).
- 02 Proved non-cytotoxic to murine B16 melanoma cells at concentrations below 0.15% in vitro (Prunus mume extract).
- 03 Inhibits melanin production via the regulation of melanogenesis-associated protein expression in melanocytes, leading to a skin-whitening effect (in vitro, observed with Prunus mume fruit extract).
- 04 Clinically shown to protect skin structural proteins against glycation and reduce Advanced Glycation End-products (AGEs), thereby diminishing yellowish pigmentation and enhancing skin tone, firmness, and transparency (for Prunus mume fruit extract).
- 05 Exhibits excellent antioxidant, anti-aging, skin moisturizing (via aquaporin-3 expression in human keratinocytes), and cellular regeneration effects against ultraviolet rays (for Prunus mume bud ethanol extract).
Transparency
Dusting Analysis
Given its demonstrated multi-functional benefits, including significant antioxidant, anti-aging, brightening, and hydrating effects, Prunus Mume Bud Extract is an active ingredient with clear efficacy, making it unlikely to be employed merely as a 'dusting' ingredient in formulations.

Formulation
Stability
Prunus Mume Bud Extract exhibits solubility in both oils and alcohols, with its aqueous solubility varying based on the specific extraction process. Common solvents utilized for extraction include ethanol, methanol, and distilled water.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically evaluated Prunus Mume Bud Extract. However, general safety assessments on Prunus mume extract indicate a favorable toxicity profile. Oral acute tests at 20 g/kg in rats and mice showed no lethal effects, and subacute toxicity studies at 3.33 g/kg for 30 days revealed no adverse effects. The extract also demonstrated no mutagenic or genotoxic potential. Prunus mume ripened seed extract has also been found to be non-toxic on the skin, suggesting a low risk of irritation or adverse reactions.
