Science
Mechanism of Action
This ingredient works through multiple pathways to enhance skin health. Its primary skin brightening action stems from the inhibition of tyrosinase, the key enzyme in melanin synthesis, thereby diminishing hyperpigmentation and promoting a more even skin tone. Abundant in flavonoids, phenolic compounds, and arbutin, it acts as a strong antioxidant, neutralizing free radicals to prevent premature aging and cellular damage. Morus Alba Leaf Powder also exhibits anti-inflammatory effects, helping to reduce skin redness and swelling, and provides antibacterial activity against both gram-positive and gram-negative bacteria, which can be beneficial in addressing acne-prone conditions. Furthermore, it supports skin rejuvenation and aids in preventing the formation of wrinkles.

Dusting Analysis
Based on the available clinical data, which showcases significant efficacy at a high concentration (75% for an extract), this ingredient is not commonly associated with 'dusting,' where minimal, ineffective amounts are used purely for marketing claims.
The Formula
Formulation
Stability
Active compounds are efficiently extracted with water, with an optimal extraction pH around 6.0. To maintain ingredient integrity, storage should be in a cool, dark place within an airtight container, ideally with a desiccant pack to prevent moisture absorption and clumping.

Safety
Safety Profile
While the CIR has not specifically reviewed Morus Alba Leaf Powder, a related ingredient, Morus Alba Root Extract, is generally regarded as safe for cosmetic use. Historical ingestion of Morus alba leaves and extracts suggests a good safety profile. Oral toxicity studies in mice showed no adverse effects at high doses. It's important to note that an FDA evaluation for 'food' use of *Morus alba Linn* leaf extract was ceased due to insufficient data for certain subpopulations and chronic dietary exposure, but this pertains to ingestion, not topical cosmetic application. A patch test is recommended due to potential individual sensitivities, despite only mild itching reported in a clinical study.
