Ingredient review
Mirabilis Jalapa Callus Extract
INCI: MIRABILIS JALAPA CALLUS EXTRACT
A gentle, plant-derived antioxidant that may help calm skin and fight free radical damage, though research is still early.
In plain English
This ingredient comes from the callus—a type of plant tissue grown in a lab—of the four o'clock flower. It's used in skincare to provide antioxidant protection (helping to neutralize unstable molecules called free radicals that can damage skin) and to soothe irritation. Because it's made from plant cells, it's considered a natural, sustainable option, but there isn't a lot of human research yet to confirm how well it works compared to more studied antioxidants like vitamin C.

What it is
A callus extract from Mirabilis jalapa, a flowering plant also known as the four o'clock flower. The callus is grown in a controlled lab environment from plant cells, ensuring a consistent and sustainable supply without harvesting wild plants.
How it works
The extract contains bioactive compounds like flavonoids and phenolic acids that act as antioxidants. When applied to skin, these compounds help neutralize free radicals generated by UV exposure and pollution, reducing oxidative stress. It also appears to have anti-inflammatory properties, which can help calm redness and irritation.
Pros
Gentle antioxidant
Provides antioxidant benefits without the irritation that some stronger antioxidants (like pure vitamin C) can cause, making it suitable for sensitive skin.
Sustainable sourcing
Produced from lab-grown plant cells, this extract doesn't require harvesting whole plants, which is better for biodiversity and ensures a consistent quality.
Cons and cautions
Limited research
Most studies are lab-based or on animals; there aren't many human clinical trials to confirm its effectiveness in real-world skincare use.
Uncommon ingredient
It's not widely used yet, so it can be harder to find in products and may be more expensive than more common antioxidants.
Best for
- People with sensitive or reactive skin looking for a gentle antioxidant
- Those interested in sustainable, plant-based skincare ingredients
Use caution if
- Anyone with a known allergy to Mirabilis jalapa or related plants (Nyctaginaceae family)
Usage tips
Safety summary
Based on available data, Mirabilis jalapa callus extract has low irritation and comedogenic potential. However, as with any new botanical, patch testing is recommended for those with very sensitive skin or plant allergies.
Research notes
Preliminary in vitro studies suggest antioxidant and anti-inflammatory activity, but human clinical data is scarce. More research is needed to confirm its benefits in skincare formulations.
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, but not specifically approved as a drug ingredient.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- Produced via plant cell culture, which uses fewer resources (water, land) than traditional farming and avoids pesticide use.
Good to know
- Callus extracts are often considered more sustainable because they don't require large-scale farming or wild harvesting.
- The four o'clock flower gets its name because it typically blooms in the late afternoon.
