Microcore Pterostilbene

Pterocarpus indicus is a valuable medicinal material. Used alone or in combination with other herbal medicines, it can treat a wide range of illnesses. Its active component pterostilbene has attracted growing attention for its effects on whitening, antioxidation, fungal inhibition and protection against heavy metal damage

Composition Information

Mechanism of Action

1. Antioxidant pathway: Directly scavenge DPPH free radicals, reduce UV-induced ROS and mitigate pigment stimulation caused by oxidation.
2. Pigment synthesis inhibition: Act on melanocytes, modulate tyrosinase-related pathways and reduce pigment production.
3. Anti-pigmentation & soothing pathway: Inhibit NF‑κB signaling pathway, downregulate PGE2 inflammatory mediators, relieve UV-triggered skin inflammation and reduce secondary pigmentation.
4. Anti-glycation pathway: Reduce the level of advanced glycation end products (AGEs) and alleviate glycation-related skin damage.
5. Functional system: Microcore encapsulation structure improves the efficacy of active ingredients.

Experimental Data

1. ROS antioxidant test: 24 h pretreatment significantly reduces intracellular ROS level, and its antioxidant effect outperforms resveratrol.
2. DPPH free radical scavenging test: At sample concentration of 10% (V/V), DPPH scavenging rate reaches 88.99%.
3. VISIA human test: After 4 weeks of application with 1% microencapsulated pterostilbene, obvious reduction in pigment spots and inflammatory red areas of skin is observed.
