What Is Prostanthera Rotundifolia Leaf Extract?
Prostanthera rotundifolia is a small, aromatic shrub native to Australia and part of the mint family Lamiaceae. Its leaves are rich in volatile oils, flavonoids and phenolic acids that give the plant its distinctive minty scent and antioxidant activity. Traditional communities used crushed leaves as a refreshing rub and in fragrant sachets, which caught the attention of modern formulators looking for gentle plant based skin care ingredients. Once harvested, the fresh or dried leaves undergo solvent or water-glycol extraction to pull out the active compounds. The resulting liquid extract is then filtered, concentrated and standardized for consistent quality before being blended into cosmetic bases. You will most often spot Prostanthera rotundifolia leaf extract in soothing moisturizers, daily face creams, after-sun gels, calming masks and lightweight serums aimed at bringing softness and comfort to the skin.

Who Can Use Prostanthera Rotundifolia Leaf Extract
Thanks to its light, non-greasy texture and soothing profile, Prostanthera rotundifolia leaf extract suits most skin types, including normal, oily, dry, combination and sensitive skin.

The extract is entirely plant derived and processed without animal by-products, so it is appropriate for both vegans and vegetarians.
No specific research flags this ingredient as unsafe during pregnancy or while breastfeeding. Still, data are limited, so this is not medical advice; anyone who is pregnant or nursing should review any new skincare product with a qualified healthcare professional.

Potential Side Effects/Adverse Reactions

- Skin irritation such as mild redness or stinging

Comedogenic Rating
Rating: 1. Prostanthera rotundifolia leaf extract is supplied as a water- or glycol-based solution that contains very little oil or wax, so it does not readily clog pores. The aromatic compounds and flavonoids present are lightweight and tend to evaporate or absorb without forming a heavy film, keeping pore blockage risk minimal.
Because of this low rating most people prone to acne or breakouts can use products featuring the extract without added concern, provided the overall formula is also low in pore-clogging ingredients.
Keep in mind that a product’s full ingredient list and texture still determine its acne-friendliness, so look at the entire formulation not just this single component.
Summary
Prostanthera rotundifolia leaf extract primarily acts as a skin conditioning agent, lending softness comfort and lightweight hydration. Its natural antioxidants and aromatic compounds help calm minor irritation while giving formulations a subtle fresh scent, making it a gentle plant-based booster in moisturizers serums and after-sun care.
The extract sits in the niche category of Australian botanicals, so it is not yet as common as aloe or chamomile but is gaining attention among brands that highlight clean and nature-inspired actives.
Current data show the ingredient is generally safe for all skin types with only rare reports of sensitivity. As with any new skincare addition, it is wise to perform a small patch test to make sure your skin gets along with the complete product that contains this minty shrub extract.
