Fermented Rice & Lavender Complex

INCI: Monascus/Lavender Flower/Rice Bran Ferment Filtrate

A fermented botanical complex that may offer antioxidant benefits and gentle skin conditioning, but research is still emerging.

beautyskincareantioxidant

In plain English

This ingredient is made by fermenting rice bran and lavender flowers with a type of red yeast called Monascus. Fermentation breaks down the plant materials into smaller molecules that may be easier for skin to absorb. It's thought to provide antioxidant protection (helping defend skin from environmental damage) and to condition the skin, making it feel softer and smoother. However, most of the evidence for these benefits comes from the individual components rather than the fermented blend itself.

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

A filtrate obtained after fermenting Monascus (a red yeast), lavender flowers, and rice bran. The fermentation process creates a mixture of amino acids, peptides, enzymes, and other bioactive compounds.

How it works

When applied to the skin, the small molecules from the fermentation process may help support the skin's natural barrier function and provide antioxidant activity by neutralizing free radicals. The rice bran component is rich in ferulic acid and vitamin E, while lavender offers soothing properties. The Monascus yeast may contribute additional peptides and enzymes.

Pros

Gentle fermentation

Fermentation breaks down ingredients into smaller molecules, which may be less likely to irritate and easier for skin to absorb.

Antioxidant potential

Rice bran and lavender are both known for antioxidant properties, which can help protect skin from daily environmental stressors.

Cons and cautions

Limited evidence

Most benefits are inferred from the individual components rather than from studies on this specific fermented blend, so effectiveness is not fully proven.

Scent sensitivity

Lavender has a distinct floral scent that may be off-putting to some, and could be irritating for those with fragrance sensitivities.

Best for

  • Those interested in fermented skincare ingredients
  • People looking for gentle antioxidant support
  • Normal to dry skin types

Use caution if

  • Those with known allergies to lavender or rice
  • Anyone with very sensitive skin should patch-test first

Usage tips

Use in a serum or essence after cleansing and before moisturizing.
Store products containing this ingredient in a cool, dark place to preserve stability.
Patch-test on your inner arm before first full-face use.

Safety summary

This ingredient is considered safe for topical use in cosmetics at typical concentrations. The fermentation process is well-controlled in manufacturing. As with any botanical ingredient, there is a small risk of allergic reaction, especially for those with sensitivities to lavender or rice.

Research notes

Research on this specific ferment filtrate is limited. However, studies on fermented rice bran and lavender extracts individually show antioxidant and anti-inflammatory potential. More clinical studies on the combined ferment are needed to confirm benefits.

Common label clues

Typical concentration
Typically 1-10% in leave-on products
Regulatory status
Generally recognized as safe for cosmetic use in the US and EU when used as intended. No specific restrictions beyond standard cosmetic regulations.
Common uses
Serums, Essences, Moisturizers
Environmental note
Rice bran is a byproduct of rice milling, so using it in cosmetics can help reduce food waste. Lavender is typically cultivated and may involve pesticide use unless organic.

Good to know

  • Fermented ingredients are often used in Korean and Japanese skincare routines.
  • The Monascus yeast is the same type used to make red yeast rice, a traditional food ingredient.
