What Is Orthosiphon Stamineus Extract?

Orthosiphon Stamineus Extract is derived from the leaves of the Jawa Tea plant, a member of the mint family native to Southeast Asia. The leaves are rich in flavonoids, rosmarinic acid and volatile oils that help support skin health. Traditionally the plant was consumed as an herbal tea for general wellness, and its soothing reputation eventually caught the attention of skincare formulators looking for gentle botanical actives.

To create the extract, harvested leaves are cleaned, dried and then subjected to a solvent or water-based extraction that pulls out the beneficial compounds. The liquid is filtered, concentrated and often standardized so each batch offers consistent levels of key molecules. The result is a fluid or powdered extract that blends easily into modern cosmetic bases.

Today you will spot Orthosiphon Stamineus Extract in a range of products such as lightweight moisturizers, hydrating sheet masks, refreshing facial mists, after-sun lotions and daily anti-aging serums where a calm comfortable finish is desired.

Orthosiphon Stamineus Extract’s Cosmetic Benefits/Uses

In skincare formulas Orthosiphon Stamineus Extract serves one main purpose.

Skin conditioning: The flavonoids and natural acids help soften rough spots, improve moisture retention and leave the complexion feeling smooth and balanced. This makes the extract a useful addition when a product aims to boost overall skin comfort without heaviness or irritation.

Who Can Use Orthosiphon Stamineus Extract

This botanical suits most skin types including dry, oily, combination and sensitive skin because it conditions without leaving a greasy film. Exceptionally reactive or allergy-prone complexions should approach with extra care since the plant belongs to the mint family and cross-sensitivities are possible.

The extract is plant derived so it is generally appropriate for vegans and vegetarians. If purity matters, check that the finished product does not carry animal-sourced solvents, glycerin or additives.

No specific warnings link Orthosiphon Stamineus Extract to pregnancy or breastfeeding concerns when used topically. Absorption is minimal yet this is not medical advice and anyone pregnant or nursing should run any skincare choices past a qualified doctor for personalized guidance.

The ingredient is not known to trigger photosensitivity so it can be worn both day and night without increasing sun-related risks. It also layers well with other common actives and does not interfere with makeup wear.

Potential Side Effects/Adverse Reactions

Responses to topical Orthosiphon Stamineus Extract differ from person to person. The points below list potential issues though most users will not experience them when the ingredient is properly formulated and used as directed.

  • Mild redness or warmth
  • Itching or stinging, especially on broken or freshly exfoliated skin
  • Allergic contact dermatitis in individuals sensitive to mint family plants
  • Eye irritation if the product migrates too close to the lash line

If any of these reactions occur stop using the product and seek medical advice if symptoms persist.

Comedogenic Rating

Rating: 1/5

Orthosiphon Stamineus Extract is primarily water soluble and contains very little oil, so it is unlikely to clog pores. Its light molecular weight and skin-soothing flavonoids make it a low-risk choice for those worried about breakouts.

Because the extract itself is not oily it is generally suitable for acne-prone skin. If it appears in a rich cream or balm the comedogenic potential will depend more on the other emollients in the formula than on the extract.

Summary

Orthosiphon Stamineus Extract is used in cosmetics for its skin-conditioning ability, helping the skin hold moisture and feel smooth through a mix of flavonoids, rosmarinic acid and gentle volatile oils. It shows up in lightweight lotions, serums and masks where a calm comfortable finish is wanted.

While not the most famous plant active it has a steady niche following, especially in Asian skincare lines that favor soothing botanicals.

Topically the ingredient is considered very safe with only rare reports of irritation or allergy, usually in people sensitive to the mint family. As with any new product it is smart to do a quick patch test first just to be sure your skin agrees.
