What Is Cinnamomum Osmophloeum Leaf Extract?
Cinnamomum Osmophloeum Leaf Extract is a plant derived ingredient obtained from the leaves of Cinnamomum osmophloeum, a type of cinnamon tree native to Taiwan. The leaves are naturally rich in essential oils such as cinnamaldehyde and eugenol alongside polyphenols and sugars that help bind water. Local communities have long brewed the leaves into herbal teas for their pleasant aroma and soothing properties. Modern cosmetic chemists noticed the leaf’s high antioxidant capacity in the 1990s and began experimenting with topical applications.
To create the cosmetic grade extract, freshly harvested leaves are cleaned, dried and milled. They are then soaked in a gentle solvent like water, propanediol or glycerin to pull out the beneficial compounds. After filtration and concentration a clear to pale amber liquid remains, ready to be blended into formulas.
Because it offers both skin feel and protection, you will spot Cinnamomum Osmophloeum Leaf Extract in hydrating toners, daily moisturizers, soothing masks, anti aging serums, after sun lotions and even beard balms or aftershaves.
Cinnamomum Osmophloeum Leaf Extract’s Cosmetic Benefits/Uses
The extract provides several skin friendly actions that make it a versatile choice for formulators.
- Antioxidant – helps neutralize free radicals generated by UV light and pollution which can lead to dullness and premature lines. Including an antioxidant supports overall skin resilience while enhancing the shelf life of the product itself
- Humectant – natural sugars in the leaf draw moisture from the environment into the upper layers of skin keeping it plump and comfortable throughout the day
- Skin Conditioning – its mix of phenolic compounds and mild essential oils can soften rough patches promote a smoother surface and support a healthy looking barrier
- Emollient – the extract adds a light silky slip that helps creams and serums glide on easily while filling in micro cracks so skin feels supple not greasy
Who Can Use Cinnamomum Osmophloeum Leaf Extract
Cinnamomum Osmophloeum Leaf Extract is generally suitable for all skin types including dry, normal, combination and oily. Its lightweight humectant and emollient profile provides hydration without leaving a heavy residue so even acne-prone skin usually tolerates it well. Extremely sensitive or highly reactive skin may want to proceed with caution because the natural aroma compounds in the extract can be stimulating.
The ingredient is plant derived and typically processed with vegan friendly solvents which makes it appropriate for both vegetarians and vegans who wish to avoid animal sourced materials.
No data suggests the extract is unsafe during pregnancy or while breastfeeding when used topically at the low levels found in cosmetics. That said this is not medical advice and anyone who is pregnant or nursing should show their routine to a qualified healthcare professional for personal guidance.
Cinnamomum Osmophloeum Leaf Extract is not known to cause photosensitivity so it will not make skin more prone to sunburn. As with any antioxidant rich botanical it can actually work alongside daily sunscreen to reinforce protection against environmental stress.
The extract is water soluble and plays well with most common actives such as niacinamide, hyaluronic acid, peptides and non-acidic vitamin C derivatives making it easy to slot into existing routines.

Comedogenic Rating
Rating: 1 / 5
Cinnamomum Osmophloeum Leaf Extract is water based and composed mostly of lightweight humectant sugars and polyphenols. It contains only trace amounts of aromatic oils, so it does not cling to pores or form an occlusive film that could trap dead cells. The small presence of cinnamaldehyde and eugenol gives it a gentle warming feel but these molecules evaporate quickly, keeping the clogging potential low.
This low score means the extract is generally suitable for people who are prone to acne or frequent breakouts.
Formulas that pair the extract with heavier butters or waxes could raise the overall comedogenicity, so always look at the complete ingredient list rather than judging a product by one plant extract alone.
Summary
Cinnamomum Osmophloeum Leaf Extract acts as an antioxidant, humectant, skin conditioner and light emollient. Polyphenols in the leaf neutralize free radicals, natural sugars pull water into the skin, phenolic compounds soften rough patches and the small oil fraction smooths the surface for a silky finish.
While beloved in Taiwanese folk remedies the extract is still a niche player in global skincare, showing up most often in boutique hydrating toners, soothing serums and aftershave balms. Its gentle profile and pleasant scent are winning it more fans year after year.
Current research and decades of traditional use indicate the ingredient is safe for topical application at the low percentages used in cosmetics. Still, every skin is unique so do a quick patch test when trying any new product that features this cinnamon leaf extract.
