Ingredient review
Ozonized Pereskia Grandifolia Callus Extract
INCI: Ozonized Pereskia Grandifolia Callus Culture Extract
A novel, lab-grown plant extract with antioxidant potential, but research is still early and benefits are not yet proven in human studies.
In plain English
This ingredient is made by growing cells from a cactus-like plant (Pereskia grandifolia) in a lab, then treating them with ozone gas. The idea is that ozonation boosts the extract's ability to fight free radicals and calm skin. Because it's produced in a controlled environment, it's more sustainable and consistent than harvesting wild plants. However, most of the evidence comes from lab tests, not human trials, so its real-world effects are still being explored.

Quick decision guide
Useful, but context matters
Ozonized Pereskia Grandifolia 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 Ozonized Pereskia Grandifolia 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 biotech ingredient derived from the callus (undifferentiated plant cells) of Pereskia grandifolia, a leafy cactus native to Central and South America. The callus is cultured in a sterile lab, then exposed to ozone to create ozonides—compounds thought to have enhanced antioxidant and antimicrobial activity.
How it works
In a cosmetic product, ozonized Pereskia grandifolia callus extract is believed to donate electrons to neutralize free radicals (unstable molecules that damage skin cells). The ozonation process may also generate compounds that help calm irritation and support the skin's natural repair processes. It is typically used at low concentrations as part of an antioxidant blend.
Pros
Sustainable sourcing
Lab-grown callus culture avoids harvesting wild plants, making it an eco-friendly choice for environmentally conscious consumers.
Antioxidant potential
Ozonation may enhance the extract's ability to neutralize free radicals, potentially helping to prevent premature skin aging from pollution and UV exposure.
Cons and cautions
Limited human evidence
Most studies are in vitro (lab-based) or on related species; there are no published clinical trials proving efficacy on human skin.
Uncertain potency
The ozonation process is not standardized across suppliers, so the strength and consistency of the active compounds can vary from product to product.
Best for
- People looking for novel, sustainably sourced antioxidants
- Those with normal to dry skin seeking extra environmental protection
Use caution if
- Anyone with a known allergy to cactus or Pereskia species (rare)
- Those who prefer ingredients with strong clinical backing
Usage tips
Safety summary
Based on limited data, ozonized Pereskia grandifolia callus extract appears to have low irritation and comedogenic potential. However, because it is a relatively new ingredient, long-term safety data is not yet available. Patch testing is recommended for first-time use.
Research notes
Research is in early stages. A few in vitro studies suggest antioxidant and antimicrobial activity, but no peer-reviewed human trials have been published as of 2025. Evidence is considered emerging.
Common label clues
- Typical concentration
- 0.1–2% in leave-on products
- Regulatory status
- Not specifically regulated as a novel ingredient in most regions; generally considered safe for cosmetic use at low concentrations, but always check individual product safety assessments.
- Common uses
- Anti-aging serums, Soothing treatments
- Environmental note
- Biotech production reduces land use and avoids pesticide application, making this a more sustainable option compared to traditional plant harvesting.
Good to know
- Ozonized ingredients are sometimes used in wound care, but cosmetic use is different and not intended to treat medical conditions.
- Pereskia grandifolia is also known as the Barbados gooseberry or leaf cactus.
