Quick decision guide

Useful, but context matters

Ozonized Rice 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.

  1. Step 1Start with the score, then check the irritation and clogging risk before judging Ozonized Rice Callus Extract.
  2. Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
  3. 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

low

Less likely to sting, burn, or bother most users, though sensitive skin can still react.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

The ingredient may be promising, but claims should be treated more cautiously.

What it is

Ozonized Oryza Sativa Callus Culture Extract is a biotech-derived ingredient produced by cultivating rice callus cells in a controlled environment and then exposing them to ozone. This process is thought to enhance the antioxidant and soothing properties of the extract.

How it works

In a cosmetic product, this ingredient is believed to work by delivering antioxidant compounds that neutralize free radicals, and by providing soothing effects that can reduce redness and irritation. The ozonation step may create unique bioactive molecules that support skin health.

Pros

Sustainable production

Made from lab-grown rice cells, reducing the need for agricultural land and water, and offering a consistent, pure ingredient.

Gentle on skin

Low irritation and comedogenic risk makes it suitable for sensitive and acne-prone skin types.

Cons and cautions

Limited research

There are few peer-reviewed studies on this specific ingredient, so its benefits are based on theoretical mechanisms rather than robust clinical data.

Higher cost

The biotech production process is more expensive than traditional plant extraction, which may be reflected in product pricing.

Best for

  • People with sensitive or easily irritated skin
  • Those looking for antioxidant protection from a sustainable source

Use caution if

  • Individuals with known allergies to rice or rice-derived ingredients
  • Those seeking ingredients with extensive clinical backing

Usage tips

Use in serums or moisturizers as part of your morning routine for antioxidant protection.
Pair with other soothing ingredients like niacinamide or panthenol for enhanced calming effects.

Safety summary

Ozonized Rice Callus Extract is considered safe for topical use with low irritation and comedogenic potential. However, due to limited research, those with rice allergies should exercise caution.

Research notes

Research on ozonized plant extracts in general suggests antioxidant and antimicrobial properties, but specific studies on this rice callus extract are scarce. Most evidence is theoretical or from related ingredients.

Common label clues

Typical concentration
Typically used at 0.1% to 2% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the EU and US, but specific ozonized ingredients may require additional safety data depending on concentration.
Common uses
Serums, Moisturizers, Anti-aging creams
Environmental note
The biotech production method is more sustainable than traditional farming, using less water and land, and avoiding pesticides.

Good to know

  • Ozonization is a process that can create new compounds with unique properties, but the exact composition of this extract can vary between manufacturers.
  • Rice callus culture is a form of plant biotechnology that allows for year-round production without seasonal limitations.
