What Is Prostanthera Incisa Leaf Extract?
Prostanthera Incisa Leaf Extract comes from the narrow serrated leaves of Prostanthera incisa, an Australian shrub in the mint family Lamiaceae. The plant is naturally rich in aromatic oils, polyphenols and flavonoids that give the extract its light herbal scent and antioxidant edge. Local communities have long crushed the leaves for their fresh aroma and soothing feel on the skin, which drew early formulators to explore its cosmetic value.
To create the ingredient, freshly harvested leaves are gently dried then soaked in a mix of water and either glycerin or a mild alcohol. This process pulls out the moisture-binding sugars, calming polyphenols and fragrant terpenes while leaving most plant solids behind. The liquid is filtered, concentrated and standardized so each batch delivers consistent performance in finished products.
Today the extract shows up in hydrating moisturizers, replenishing serums, sheet masks, after-sun lotions, lightweight mists and even scalp tonics. Brands favor it when they want a plant based humectant that also leaves skin feeling soft and comfortable.
Prostanthera Incisa Leaf Extract’s Cosmetic Benefits/Uses
This multitasking botanical brings more than a pleasant scent to a formula
- Humectant: The extract pulls moisture from the air and helps hold it on the skin surface. This keeps skin looking plump and smooth while reducing the tight feel that can follow cleansing or sun exposure.
- Skin Conditioning: Its blend of lightweight oils and polyphenols softens rough patches, supports the skin barrier and leaves a silky afterfeel without heaviness.
Who Can Use Prostanthera Incisa Leaf Extract
The extract is generally well tolerated by most skin types including dry, normal, combination and sensitive skin thanks to its lightweight humectant profile. Oily and acne‐prone users can also benefit because it hydrates without leaving a greasy residue.
Prostanthera Incisa Leaf Extract is plant derived with no animal by-products so it is suitable for vegans and vegetarians.
There is no specific data showing risk for pregnant or breastfeeding women when the extract is used topically at the low levels found in cosmetics. Still, this is not medical advice and anyone who is expecting or nursing should run any new skincare product past a healthcare provider to be safe.
The ingredient is not known to cause photosensitivity so daytime use does not demand extra sun precautions beyond a regular broad-spectrum sunscreen.

Comedogenic Rating
Rating: 1 / 5
Prostanthera Incisa Leaf Extract is mostly water based with small amounts of lightweight aromatic oils and polyphenols that do not tend to block pores. It absorbs quickly and leaves minimal residue, which keeps the risk of clogging low.
Suitable for skin that is prone to acne or breakouts.
Keep in mind that the overall pore-clogging potential of a finished product also depends on the other ingredients and the formula’s texture.
Summary
Prostanthera Incisa Leaf Extract works as a humectant and skin-conditioning agent. Its natural sugars draw moisture to the skin surface while the plant’s gentle oils and antioxidants soften rough spots and support a comfortable barrier.
The extract is still a bit of a niche player compared with big-name hydrators like glycerin or hyaluronic acid but formulators who want a botanical twist are using it more often in mists, serums and light creams.
Topical use is considered low risk for most people with few reports of irritation or allergy. As with any new skincare product it is wise to do a small patch test first to rule out personal sensitivities.
