Ingredient review
Fermented Frankincense Extract
INCI: SACCHAROMYCES/BOSWELLIA SERRATA GUM FERMENT EXTRACT
A gentle, fermented botanical extract that may help calm redness and support skin's natural defenses, though research is still early.
In plain English
This ingredient is made by fermenting frankincense gum (the resin from the Boswellia serrata tree) with yeast. The fermentation process breaks down the plant compounds into smaller, potentially more absorbable molecules. In skincare, it's used to soothe irritation and provide antioxidant protection, similar to how green tea or vitamin E work. Think of it as a modern, biotech version of an ancient herbal remedy.

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 fermented extract of Boswellia serrata gum resin (frankincense) using Saccharomyces (baker's yeast). The fermentation creates a unique blend of boswellic acids, polysaccharides, and yeast metabolites.
How it works
The boswellic acids in the extract are known to help calm inflammatory pathways in skin cells, while the fermentation process may enhance the bioavailability of these compounds. The yeast metabolites also contribute antioxidant activity, helping to neutralize free radicals that can cause premature aging.
Pros
Gentle soothing potential
The boswellic acids in this extract are known for their anti-inflammatory properties, which may help calm redness and irritation without harsh side effects.
Biotech-enhanced absorption
Fermentation breaks down larger plant molecules into smaller ones, potentially making the active compounds more available to the skin compared to a standard extract.
Cons and cautions
Limited research on this specific form
While boswellia itself has some studies, there are very few human trials on this exact fermented extract, so its benefits are mostly theoretical or based on related ingredients.
Potential for rare allergies
Because it contains yeast and plant resin derivatives, a small number of people may experience contact dermatitis or allergic reactions.
Best for
- People with sensitive or easily irritated skin looking for a gentle soothing ingredient
- Those interested in fermented skincare ingredients for their potential microbiome benefits
Use caution if
- Individuals with a known allergy to yeast or Boswellia serrata (frankincense)
Usage tips
Safety summary
This ingredient is considered safe for topical use in cosmetics at typical concentrations. The main risk is rare allergic reactions in sensitive individuals. Always patch test a new product.
Research notes
Research on boswellia extracts (non-fermented) shows anti-inflammatory and antioxidant activity in lab and animal studies. However, specific human clinical trials on this fermented version are lacking, so evidence is considered emerging.
Common label clues
- Typical concentration
- 0.5% to 5% in leave-on products
- Regulatory status
- Generally recognized as safe for cosmetic use in the EU and US when used at typical concentrations. Not a drug ingredient.
- Common uses
- Serums, Moisturizers, Face oils, Masks
- Environmental note
- Boswellia serrata is a threatened species in some regions due to overharvesting; look for brands that source from certified sustainable suppliers.
Good to know
- Fermented ingredients like this are often marketed as 'postbiotic' because they contain metabolites from the fermentation process that may support skin health.
- The Boswellia serrata tree is native to India and parts of Africa; sustainable harvesting practices are important for environmental conservation.
