Ingredient review
Kalanchoe Leaf Extract
INCI: KALANCHOE GASTONIS-BONNIERI LEAF EXTRACT
A gentle plant extract with potential soothing and antioxidant benefits, but research on this specific species is limited.
In plain English
This is an extract made from the leaves of a succulent plant called Kalanchoe gastonis-bonnieri, a relative of the more common 'mother of thousands' houseplant. In skincare, it's used to help calm irritated skin and provide some protection against environmental stress, thanks to natural compounds like flavonoids. Because it's a newer ingredient in cosmetics, most of what we know comes from traditional use and early lab studies, not large human trials.

Quick decision guide
Useful, but context matters
Kalanchoe Leaf Extract is generally a lower-concern ingredient when the full formula suits your skin.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Kalanchoe Leaf Extract.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A water-soluble extract derived from the leaves of Kalanchoe gastonis-bonnieri, a succulent plant native to Madagascar. The extract contains flavonoids, polyphenols, and other bioactive compounds that are thought to have soothing and antioxidant effects on the skin.
How it works
The flavonoids and polyphenols in the extract can help neutralize free radicals (unstable molecules that damage skin cells), which may reduce oxidative stress. Some compounds in Kalanchoe species have also shown anti-inflammatory activity in lab studies, which could help calm redness and irritation when applied topically.
Pros
Gentle soothing potential
Early research and traditional use suggest it may help calm redness and irritation without causing stinging or dryness, making it a good option for sensitive skin.
Antioxidant support
Contains flavonoids that can help protect skin from daily environmental damage, such as pollution and UV-induced free radicals, though it's not a substitute for sunscreen.
Cons and cautions
Limited research on this species
Most studies on Kalanchoe focus on other species like K. pinnata. There is very little published data specifically on K. gastonis-bonnieri, so its benefits are inferred rather than proven.
Potential for variable quality
As a natural extract, its potency can vary based on growing conditions, harvest time, and extraction method, meaning not all products will deliver the same level of benefit.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, plant-based antioxidant in their routine
Use caution if
- Individuals with known allergies to Kalanchoe or Crassulaceae plants
- Those seeking a well-studied, high-efficacy antioxidant (consider alternatives)
Usage tips
Safety summary
Kalanchoe gastonis-bonnieri leaf extract is considered safe for topical cosmetic use at typical concentrations. There are no known toxicity concerns, but as with any plant extract, individuals with plant allergies should patch test. Oral ingestion of Kalanchoe plants can be toxic to pets and humans, but this does not apply to topical use.
Research notes
Research on Kalanchoe species, particularly K. pinnata, shows anti-inflammatory and antioxidant activity in lab and animal studies. However, specific studies on K. gastonis-bonnieri are scarce. More human clinical trials are needed to confirm its efficacy in skincare.
Common label clues
- Typical concentration
- 0.1% to 2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used according to good manufacturing practices. No specific restrictions are in place.
- Common uses
- Soothing serums, Calming moisturizers, After-sun products
- Environmental note
- Kalanchoe species are drought-tolerant succulents that can be cultivated with relatively low water input, but wild harvesting should be avoided to protect native biodiversity.
Good to know
- Kalanchoe gastonis-bonnieri is sometimes called 'donkey ears' due to the shape of its leaves.
- This extract is often used in 'clean beauty' formulations as a natural alternative to synthetic soothing agents.
