What Is Bacillus/Dahlia Variabilis Flower Extract Ferment Extract?
Bacillus/Dahlia Variabilis Flower Extract Ferment Extract is a skin care ingredient that starts with the colorful dahlia flower. Petals are gathered and steeped in a solvent, usually water or a gentle mix of water and glycerin, to pull out the flower’s natural sugars, minerals and antioxidant compounds. This liquid is then inoculated with a friendly Bacillus strain that feeds on the plant material during a carefully controlled fermentation step. Fermentation breaks large molecules into smaller ones that sit more comfortably on skin and can boost the extract’s overall activity. Once the process is complete the mixture is filtered, purified and blended with a light preservative so it stays stable in a cosmetic formula.
The idea of using fermented botanicals took off when Korean beauty brands began showing that the process can make plant extracts more potent yet gentler. Dahlia flowers were added to the list because they are rich in fructans and flavonoids that can soothe and moisturize skin. Today you will find this fermented extract in hydrating serums, all-in-one essences, calming moisturizers, sheet masks and lightweight anti-aging lotions that aim to give skin a plump refreshed look without heaviness.
Bacillus/Dahlia Variabilis Flower Extract Ferment Extract’s Cosmetic Benefits/Uses
This ingredient is prized for one main job in skin care.
Skin conditioning: The broken-down sugars and amino acids formed during fermentation help attract water and hold it at the surface of the skin. This softens rough spots improves suppleness and leaves a smooth feel after application. The naturally occurring antioxidants in the flower can also support the skin’s own barrier so the complexion looks brighter and more rested over time.
Who Can Use Bacillus/Dahlia Variabilis Flower Extract Ferment Extract
This fermented flower extract is generally suitable for all skin types. Dry and mature skin benefit from its water-binding sugars while oily or combination skin appreciate that it feels light and non-greasy. Sensitive complexions usually tolerate it well because fermentation reduces many of the larger plant molecules that might otherwise irritate. The main group that should be cautious are individuals allergic to flowers in the Asteraceae family or anyone who has reacted to fermented ingredients in the past.
The material is derived solely from a plant source and a food-grade bacterial culture, so it aligns with vegan and vegetarian preferences as long as the finished product contains no added animal-derived ingredients.
No specific data links this extract to problems during pregnancy or breastfeeding. It is viewed as low risk when applied topically, but this is not medical advice and pregnant or nursing women should clear any new skin care product with their physician before use.
The extract is not known to make skin more sensitive to sunlight, and it does not interfere with common actives like vitamin C or retinoids.

Comedogenic Rating
Rating: 0 / 5
Bacillus/Dahlia Variabilis Flower Extract Ferment Extract is water based and contains no heavy oils or waxes that can clog pores. The small fermented molecules rinse away easily and do not linger in follicle openings, which is why it sits at the non-comedogenic end of the scale.
Suitable for acne-prone or breakout-prone skin.
Keep in mind that the final product formula matters too. If the extract is paired with thick butters or occlusive silicones the overall product could still trigger bumps even though the extract itself is rated 0.
Summary
Bacillus/Dahlia Variabilis Flower Extract Ferment Extract is mainly used to condition skin. Fermentation breaks the dahlia flower’s natural sugars and amino acids into smaller pieces that pull in moisture and soften rough patches. Antioxidant compounds left in the mix help support a stronger skin barrier so the face looks smoother and more rested over time.
The ingredient has found a steady following in K-beauty inspired serums and masks but it is still a niche pick compared with classic hydrators like aloe or glycerin. Brands that focus on fermented botanicals tend to feature it most.
Overall it is considered low risk for topical use with few reports of irritation. Even so every skin is unique so it is smart to patch test any new product that contains this extract before applying it to the entire face.
