Ingredient review
Myrothamnus Callus Extract
INCI: MYROTHAMNUS FLABELLIFOLIA CALLUS CULTURE EXTRACT
A lab-grown extract from the resurrection plant that may help shield skin from environmental damage and support moisture retention, though human studies are still limited.
In plain English
This ingredient is made by growing cells from a special plant called the resurrection plant in a lab. That plant can survive almost completely drying out and then bounce back to life when watered. The extract is thought to help skin cells resist stress from things like pollution and UV rays, and it may also help skin hold onto moisture better. Because it's made in a lab, it's more sustainable and consistent than harvesting the whole plant.

Quick decision guide
Useful, but context matters
Myrothamnus Callus 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 Myrothamnus Callus 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 biotechnologically produced extract from the callus (undifferentiated plant cells) of Myrothamnus flabellifolia, a plant native to southern Africa known for its extreme drought tolerance.
How it works
The extract contains protective compounds like oligosaccharides and phenolic acids that are believed to help skin cells activate their own defense mechanisms against environmental stressors, such as oxidative damage and dehydration. It may also support the skin's natural moisture barrier by encouraging the production of certain proteins and lipids.
Pros
Sustainable sourcing
Made from lab-grown plant cells, this extract avoids harvesting wild plants and ensures a consistent, high-quality supply.
Potential stress protection
Early research suggests it may help skin cells resist damage from UV and pollution, which could slow visible signs of aging.
Cons and cautions
Limited human evidence
Most studies so far are lab-based or on skin models, so the real-world benefits for everyday skin are not yet fully proven.
Higher cost
Because it's produced using biotechnology, products containing this ingredient tend to be more expensive than those using common plant extracts.
Best for
- People with dry or dehydrated skin looking for extra moisture support
- Those concerned about environmental damage and premature aging
Use caution if
- Individuals with known allergies to Myrothamnus or related plants (rare)
Usage tips
Safety summary
Myrothamnus flabellifolia callus culture extract is considered safe for topical use with low irritation and comedogenic potential. Allergic reactions are rare, but patch testing is recommended for sensitive individuals.
Research notes
Preliminary in vitro and ex vivo studies suggest antioxidant and moisture-retention benefits, but well-controlled human clinical trials are lacking. The evidence is promising but still emerging.
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, with no specific restrictions.
- Common uses
- Anti-aging serums, Moisturizers, Eye creams
- Environmental note
- Produced via plant cell culture, which reduces land and water use compared to traditional farming and protects wild plant populations.
Good to know
- The resurrection plant can lose up to 95% of its water and still revive, which is why its extract is studied for skin hydration and stress resistance.
- This ingredient is often found in high-end or 'clean beauty' serums and moisturizers.
