Orthosiphon Stamineus Extract

Orthosiphon stamineus extract comes from the leaves of a plant traditionally used in Asian herbal medicine, commonly brewed as a tea. In skincare formulations, it functions as a skin conditioning agent.The extract contains active compounds that appear to influence sebum regulation at a biochemical level, making it of particular interest for those managing oily or combination skin.

The mechanism appears to centre on the enzyme 5-α reductase type 1, which plays a role in sebum production. Research suggests that Orthosiphon stamineus extract may help reduce the expression and activity of this enzyme in skin cells, thereby moderating sebum secretion.By lowering sebum production, the extract may help reduce the shiny, oily appearance of skin and the enlarged pores often associated with excess oil.

This ingredient is typically found in formulations designed for oily or combination skin, such as serums, essences or lightweight moisturisers. It works well alongside other sebum-regulating ingredients. Use consistently as part of your routine, as skin conditioning benefits tend to develop with regular application.

Orthosiphon stamineus extract is generally well-tolerated in skincare. Those taking medications metabolised by cytochrome P450 enzymes may wish to consult a healthcare professional, though topical skincare use presents minimal systemic absorption risk.
