Question 5

How does Orthosiphon Stamineus Leaf Extract work chemically?

Accepted Answer

This material is a complex plant extract containing polyphenols, flavonoids, caffeic acid derivatives, and mineral salts, with composition varying by harvest, solvent, and standardization. Typical cosmetic use is often around 0.1% to 5%, and phenolic-rich extracts are best protected from excess heat, light, oxygen, and high-pH conditions to limit color shift and activity loss.
