Pichia/Safflower Ferment Filtrate
INCI: Pichia/Safflower Flower Ferment Filtrate
A gentle, fermented ingredient that may help calm skin and provide antioxidant protection, though research is still emerging.
In plain English
This ingredient is made by fermenting safflower flowers with a type of yeast called Pichia. The fermentation process breaks down the plant material and creates new compounds that can be beneficial for the skin. It's thought to help soothe irritation and protect against environmental damage, but it's not as well-studied as some other fermented ingredients.

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 Pichia/Safflower Ferment Filtrate.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

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 filtrate obtained from the fermentation of safflower (Carthamus tinctorius) flowers by the yeast Pichia pastoris. The process yields a liquid rich in peptides, amino acids, and other bioactive molecules.
How it works
The fermentation process creates small molecules that can penetrate the skin's surface. These molecules may help calm inflammation by reducing the production of pro-inflammatory signals, and they can also act as antioxidants, neutralizing free radicals that cause premature aging.
Pros
Gentle soothing
The fermentation process creates compounds that may help calm redness and irritation without harsh chemicals, making it suitable for reactive skin.
Antioxidant support
It can help protect skin from environmental stressors like pollution and UV damage, which contribute to premature aging.
Cons and cautions
Limited research
Most evidence comes from lab studies or small trials; large-scale human studies confirming its benefits are still lacking.
Higher cost
The fermentation process is more complex and costly than simple extraction, which can make products containing this ingredient more expensive.
Best for
- Those with sensitive or easily irritated skin
- Anyone looking for a gentle antioxidant ingredient
Use caution if
- Those with a known allergy to safflower or yeast
Usage tips
Safety summary
Considered safe for topical use with a low risk of irritation or allergic reactions. Patch testing is recommended for those with known sensitivities to yeast or safflower.
Research notes
Emerging evidence suggests antioxidant and anti-inflammatory properties, but more rigorous human studies are needed to confirm efficacy and compare it to other fermented ingredients.
Common label clues
- Typical concentration
- Typically 1-5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use; no specific restrictions in the US or EU.
- Common uses
- Serums, Moisturizers, Toner
- Environmental note
- Safflower is a drought-tolerant crop, and fermentation is a relatively low-energy process, making this ingredient moderately sustainable.
Good to know
- Fermented ingredients are often more easily absorbed by the skin because the fermentation process breaks down larger molecules into smaller ones.
- Safflower flowers are a natural source of antioxidants, and fermentation may boost their activity.
