Ingredient review
Cloudberry Callus Extract
INCI: RUBUS CHAMAEMORUS CALLUS
A gentle, antioxidant-rich plant stem cell extract that may help protect skin from environmental stress, though human studies are limited.
In plain English
Cloudberry callus extract is made by growing cloudberry plant cells in a lab, then harvesting the beneficial compounds they produce. It's rich in antioxidants like ellagic acid and vitamin C, which can help neutralize free radicals from UV and pollution. Because it's produced in a controlled environment, it's consistent and sustainable. In skincare, it's used to soothe and protect the skin, but most of the evidence comes from lab studies, not large human trials.

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 derived from the callus (undifferentiated plant cells) of the cloudberry (Rubus chamaemorus), a hardy Arctic berry plant. The callus is grown in a sterile lab culture to concentrate active compounds like ellagic acid, flavonoids, and vitamin C.
How it works
The extract provides antioxidant protection by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It also has mild anti-inflammatory properties, helping to calm redness and irritation. In formulations, it is typically used at low concentrations to boost the product's overall antioxidant capacity without causing irritation.
Pros
Gentle antioxidant
Provides free-radical protection with a very low risk of irritation, making it suitable for sensitive skin types.
Sustainable sourcing
Produced via plant cell culture, which avoids harvesting wild plants and ensures a consistent, eco-friendly supply.
Cons and cautions
Limited human evidence
Most research is in lab settings or on animal cells; there are few published human trials confirming its benefits on skin.
Higher cost
The biotech production process makes it more expensive than many common antioxidants, which may increase product prices.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with sensitive or reactive skin who want protection without irritation
Use caution if
- Those seeking a proven, high-potency antioxidant with strong clinical backing
Usage tips
Safety summary
Cloudberry callus extract is considered safe for topical use with a low irritation and comedogenic risk. No significant adverse effects have been reported in cosmetic formulations.
Research notes
Evidence is primarily from in vitro and ex vivo studies showing antioxidant and anti-inflammatory activity. Human clinical data is sparse, so the ingredient is best viewed as a supportive antioxidant rather than a primary active.
Common label clues
- Typical concentration
- 0.1% to 2%
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US, with no specific restrictions at typical use levels.
- Common uses
- Serums, Moisturizers, Eye creams
- Environmental note
- The biotech production method reduces pressure on wild cloudberry populations and uses fewer resources than traditional farming.
Good to know
- Cloudberry callus extract is often marketed as 'Arctic berry stem cells' and is prized for its ability to survive extreme cold, which may translate to skin resilience.
- It is not the same as cloudberry seed oil or fruit extract; the callus version is a lab-grown concentrate.
