What Is Backhousia Citriodora Leaf Extract?
Backhousia Citriodora Leaf Extract comes from the fragrant leaves of Backhousia citriodora, a tree native to the rainforests of Queensland Australia and better known as lemon myrtle. The leaves are naturally high in citral, a lemon scented compound that gives the extract its crisp aroma and contributes to its toning qualities. Aboriginal communities have long valued the plant for its fresh smell and cleansing properties; modern formulators picked up on these traits in the 1990s when essential oil distillation of lemon myrtle took off, paving the way for water- and glycerin-based leaf extracts now used in skincare.
The extract is usually produced by drying the leaves then steeping them in a solvent such as water, glycerin or a mild alcohol. The liquid is filtered to remove plant solids, leaving a clear or lightly tinted solution rich in aromatic compounds and flavonoids that can be blended straight into cosmetic bases.
You will most often see Backhousia Citriodora Leaf Extract in toners, clarifying mists, lightweight moisturizers, sheet masks, after-shave lotions and anti-blemish spot treatments where a fresh feel and pore refining effect are desired.
Backhousia Citriodora Leaf Extract’s Cosmetic Benefits/Uses
Formulators reach for this botanical when they need a multitasking boost that leaves skin feeling both refreshed and comfortable.
- Astringent: Helps tighten the look of pores, minimizes excess surface oil and delivers a clean matte finish that can make skin appear smoother
- Skin Conditioning: Provides a gentle soothing sensation, supports softness, adds a light layer of hydration and supplies antioxidant plant compounds that help keep skin looking healthy
Who Can Use Backhousia Citriodora Leaf Extract
This leaf extract is generally well received by most skin types including normal, combination, oily and acne-prone skin thanks to its light astringent action and non-greasy finish. Dry or sensitised skin can also benefit from its conditioning properties, though these users may prefer it blended into richer formulas so the toning effect does not feel too tight. Those with highly reactive or fragrance-allergic skin should proceed cautiously since the natural citral content, while low, can be a trigger for some people.
The ingredient is plant derived and produced without animal by-products so it fits vegan and vegetarian lifestyles.
No specific warnings exist for topical use during pregnancy or breastfeeding. That said this is not medical advice and anyone who is pregnant or nursing should check with a healthcare professional before adding new skincare to their routine.
Backhousia Citriodora Leaf Extract does not make skin more sensitive to sunlight and can be used day or night. It is also water soluble which means it rinses cleanly from the skin and will not interfere with most other active ingredients in a routine.
Potential Side Effects/Adverse Reactions
Reactions to Backhousia Citriodora Leaf Extract vary from person to person. The points below describe potential side effects that could occur but are unlikely for the average user when the ingredient is properly formulated and used as directed.
- Mild stinging or burning on very sensitive skin
- Temporary redness or flushing, especially if applied to freshly exfoliated skin

If any irritation or discomfort develops discontinue use and consult a qualified healthcare professional
Comedogenic Rating
Rating: 0 – 1
Because it is a water based botanical with almost no oils, waxes or heavy emollients, Backhousia Citriodora Leaf Extract has little opportunity to lodge inside pores and form blockages. Its active constituents are mainly lightweight aromatic molecules and polyphenols that rinse away easily, so the extract sits at the very bottom of the comedogenic scale.
Good news for those prone to acne and breakouts: the ingredient is unlikely to trigger new spots.
Overuse of any astringent can push skin to overcompensate with extra oil, so balance it with adequate hydration in your routine.
Summary
Backhousia Citriodora Leaf Extract acts as a gentle astringent that tones the look of pores while doubling as a skin-conditioning booster that leaves the surface calm and softly hydrated. Flavonoids and natural citral give the extract its pore refining feel and its ability to freshen and soothe.
Although lemon myrtle essential oil enjoys the spotlight in aromatherapy, the leaf extract is still a niche addition in mainstream skincare, appearing mostly in indie toners, mists and lightweight lotions. Those who have discovered it often appreciate the crisp scent and non-greasy finish.
Topical use is considered low risk for most skin types with only minor chances of irritation in very sensitive or fragrance-reactive individuals. As with any new cosmetic ingredient it is wise to perform a quick patch test when trying a product that contains Backhousia Citriodora Leaf Extract just to be safe.
