Science
Mechanism of Action
Pyrus Pyrifolia Fruit Juice functions through a synergistic blend of bioactive compounds, including arbutin, protocatechuic acid (PCA), flavonoids, triterpenoids, and phenolic acids like chlorogenic acid. Arbutin and PCA directly inhibit tyrosinase, the enzyme crucial for melanin production, thereby visibly reducing hyperpigmentation and promoting a brighter complexion. Flavonoids, triterpenoids, and phenolic acids act as potent antioxidants, neutralizing free radicals and mitigating oxidative stress-induced damage. Furthermore, compounds such as chlorogenic acid may down-regulate pro-inflammatory markers, contributing to anti-inflammatory benefits. Its natural sugar and water content provides emollient and hydrating effects, supporting skin barrier function.

Key findings
- 01 In melanocytes from mice treated with α-MSH, extracts from various Korean pear (Pyrus pyrifolia) cultivars demonstrated approximately 50% inhibition of tyrosinase activity.
- 02 An unripe Korean pear (Pyrus pyrifolia cv. Manpungbae) extract achieved 4.9% tyrosinase inhibition and a 74% reduction in cellular melanin compared to untreated cells.
- 03 In B16F10 mouse melanoma cells, most Pyrus pyrifolia cultivar extracts inhibited melanin synthesis by roughly 50%.

Dusting Analysis
There is no available data to suggest that Pyrus Pyrifolia Fruit Juice is commonly 'dusted' or used at ineffective concentrations in formulations.
The Formula
Formulation
Stability
Pear juices naturally exhibit pH values ranging from 3.3 to 4.6. When converting to a powder form, utilizing low-temperature drying methods is crucial to minimize the degradation of nutrients and preserve the integrity of its bioactive compounds.
