What Is Barosma Betulina Leaf/Twig Extract?
Barosma Betulina Leaf/Twig Extract comes from the leaves and young stems of Barosma betulina, a small evergreen shrub native to the mountain regions of South Africa. The plant is better known as buchu and has long been valued by local communities for its fragrant, minty leaves. In the late 19th and early 20th centuries perfumers began distilling buchu oil for its crisp herbal note, and skin care brands eventually took notice of its soothing qualities.
The extract is obtained by first drying the harvested leaves and twigs then subjecting them to a gentle solvent or water-based extraction. This pulls out key bioactive compounds such as flavonoids, diosphenol and volatile terpenes that give the ingredient its characteristic scent and skin conditioning traits. After filtration and concentration the liquid extract is standardized for consistency and added to cosmetic formulations.
Today Barosma Betulina Leaf/Twig Extract appears in a range of products including lightweight facial moisturizers, calming lotions, after-sun gels, toners, sheet masks and targeted treatment serums that focus on keeping skin soft and comfortable.
Barosma Betulina Leaf/Twig Extract’s Cosmetic Benefits/Uses
In cosmetics this botanical is prized for one key role: skin conditioning. It helps keep the skin’s surface smooth, hydrated and comfortable by reinforcing the natural moisture barrier and delivering soothing plant compounds that can reduce feelings of tightness or irritation after cleansing or environmental stress.
Who Can Use Barosma Betulina Leaf/Twig Extract
This extract is generally suitable for all skin types, including dry, normal, combination and oily skin, because it focuses on gentle hydration and barrier support without leaving a heavy or greasy film. Sensitive skin often tolerates it well thanks to its calming flavonoids, though individuals with known allergies to the Rutaceae family should proceed with caution.
As a plant-derived material obtained from leaves and twigs, the ingredient is appropriate for both vegetarians and vegans. No animal-derived substances or animal testing are required in its standard production process, which makes it a common choice for cruelty-free formulas.
Pregnant or breastfeeding individuals are not specifically restricted from using topical products containing Barosma Betulina Leaf/Twig Extract. The available data do not point to hormone-disrupting activity or penetration levels that would raise concern. That said, this is not medical advice and anyone who is pregnant or nursing should discuss new skincare products with a qualified healthcare professional before adding them to a routine.
The extract does not make skin more sensitive to sunlight and has no documented photosensitising properties. It also plays well with most other skincare actives, so users can comfortably layer it alongside acids, retinoids or vitamin C unless a personal sensitivity exists.

If any of the above reactions occur discontinue use and consult a healthcare professional for guidance.
Comedogenic Rating
Rating: 1/5
Barosma Betulina Leaf/Twig Extract is a lightweight botanical rich in volatile flavonoids and terpenes that do not sit heavily on the skin or clog pores. It contains very little fatty material, so it has minimal occlusive potential compared with heavier oils or butters. A rating of 1 reflects a low chance of blocking pores while acknowledging that any plant extract can trigger breakouts in a small number of highly reactive users.
Suitable for acne-prone or breakout-prone skin in most cases.
No data suggest the extract interferes with common acne treatments, making it easy to slot into routines built around salicylic acid, benzoyl peroxide or retinoids.
Summary
Barosma Betulina Leaf/Twig Extract functions mainly as a skin conditioner, helping to keep the surface smooth, hydrated and comfortable. Its mix of flavonoids, diosphenol and gentle aromatic terpenes supports the moisture barrier, calms minor redness and leaves a subtle fresh scent.
The ingredient enjoys moderate popularity. It is not as mainstream as aloe or chamomile but appears increasingly in niche clean beauty lines, after-sun gels and lightweight moisturizers looking for a unique herbal twist.
Topical use is considered low risk with only rare reports of irritation or allergy in people sensitive to the Rutaceae family. As with any new skincare product, perform a small patch test first to make sure your skin agrees with it.
