Ingredient review
Cestro Leaf Extract
INCI: Cestrum Latifolium Leaf Extract
A gentle botanical extract with traditional use but very limited modern cosmetic research; may offer soothing and antioxidant benefits but is not a proven powerhouse.
In plain English
This is an extract made from the leaves of a plant called Cestrum latifolium. In traditional medicine, it has been used for various purposes, but in skincare, it's added for its potential to calm the skin and fight free radicals (unstable molecules that can damage skin cells). Because there isn't much scientific research on this specific extract in modern cosmetics, it's best to think of it as a nice-to-have botanical addition rather than a must-have active ingredient.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.

emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A leaf extract from Cestrum latifolium, a flowering shrub native to parts of Central and South America. The extract is typically obtained by soaking the leaves in a solvent (like water or alcohol) to pull out beneficial compounds.
How it works
The extract contains various plant compounds, such as flavonoids and saponins, which are thought to provide antioxidant activity (neutralizing free radicals) and mild anti-inflammatory effects. In a cosmetic product, it may help reduce redness or irritation and protect the skin from environmental stressors, though the exact mechanisms are not well-studied in a cosmetic context.
Pros
Gentle on skin
The extract is considered low-irritation and low-comedogenic, making it suitable for sensitive and acne-prone skin types.
Traditional use
Cestrum latifolium has a history of use in folk medicine for its soothing properties, which may translate to mild calming effects in skincare.
Cons and cautions
Limited research
There are very few peer-reviewed studies on this extract's efficacy in cosmetic formulations, so its benefits are largely anecdotal or theoretical.
Potential allergen
As a member of the nightshade family, it may cause allergic reactions in sensitive individuals, though this is rare.
Best for
- People with sensitive or easily irritated skin looking for gentle botanical ingredients
- Those interested in trying plant-based skincare with traditional herbal roots
Use caution if
- Individuals with known allergies to nightshade plants (e.g., tomatoes, potatoes, eggplants) should exercise caution
- Anyone seeking a well-researched, proven active ingredient for specific skin concerns
Usage tips
Safety summary
Cestrum latifolium leaf extract is considered safe for topical cosmetic use at typical concentrations. However, due to its classification in the nightshade family, individuals with known allergies to Solanaceae plants should use caution. There are no major safety concerns reported in the literature.
Research notes
Research on Cestrum latifolium leaf extract in cosmetics is extremely limited. Most available data comes from traditional medicine or preliminary in vitro studies. Its antioxidant and anti-inflammatory potential is plausible but not well-confirmed in human skin studies.
Common label clues
- Typical concentration
- Typically used at 0.1–2% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations, though it is not specifically reviewed by the Cosmetic Ingredient Review (CIR) panel.
- Common uses
- Soothing serums, Calming moisturizers, Anti-aging creams
- Environmental note
- Cestrum latifolium is a hardy shrub that can be cultivated, but wild harvesting practices are not well-documented. Look for sustainably sourced extracts if environmental impact is a concern.
Good to know
- Cestrum latifolium is sometimes called 'cestro' or 'wild jasmine' but is not related to true jasmine.
- The extract is often used at low concentrations (under 2%) and is rarely the star ingredient in a formula.
