What Is Aspergillus/Prunus Serrulata Flower Ferment Extract?
Aspergillus/Prunus Serrulata Flower Ferment Extract comes from cherry blossom petals (Prunus serrulata) that have been fermented with the friendly mold Aspergillus. The fermentation step breaks down the petals into a cocktail of skin caring molecules such as amino acids, small peptides, flavonoids, organic acids and natural sugars. Cherry blossoms have long been prized in Japan and Korea for their beauty benefits and the idea of fermenting them grew out of traditional food and skincare practices where fermentation is used to unlock nutrients.
To make the extract, freshly harvested petals are cleaned, then mixed with a culture of Aspergillus under warm, oxygen-controlled conditions. Over several days the microorganism releases enzymes that gently dissolve the plant material and enrich the liquid with new by-products that are kind to skin. The mixture is then filtered, purified and stabilized so it can be added to modern formulas.
You will mainly see Aspergillus/Prunus Serrulata Flower Ferment Extract in lightweight moisturizers, brightening or anti-aging serums, essence lotions, sheet masks and soothing after-sun products. Formulators like it because it is water soluble, has a mild natural scent and pairs well with other botanical actives.
Aspergillus/Prunus Serrulata Flower Ferment Extract’s Cosmetic Benefits/Uses
This floral ferment serves a couple of key roles in skincare formulas:
- Skin conditioning: The blend of amino acids, sugars and antioxidants helps soften rough patches, support the skin barrier and improve overall texture which leaves the face feeling smooth and supple
- Emollient: It forms a light, breathable film on the surface that reduces moisture loss while lending a silky finish without heaviness making it ideal for all-day hydration in both creams and serums
Who Can Use Aspergillus/Prunus Serrulata Flower Ferment Extract
This gentle ferment is generally suitable for all skin types including dry, oily, normal and combination because it offers light hydration without clogging pores or leaving a greasy feel. Sensitive skin usually tolerates it well thanks to its soothing amino acids though anyone with a known allergy to cherry blossoms or fermented ingredients should stay cautious.
The extract is plant based and produced with the help of a microscopic fungus so it contains no animal material or by-products. That makes it a friendly option for both vegans and vegetarians.

Aspergillus/Prunus Serrulata Flower Ferment Extract does not increase photosensitivity so there is no added risk of sunburn after use. It also plays nicely with most other common actives such as vitamin C, niacinamide and hyaluronic acid.

Comedogenic Rating
Rating: 1 / 5
Aspergillus/Prunus Serrulata Flower Ferment Extract is water based and contains virtually no heavy oils or waxes that would block pores. Its main components are small amino acids, sugars and antioxidants that sit lightly on the skin and rinse away easily. Because it is fermented the molecular size of many compounds is reduced which further lowers the chance of pore congestion.
With such a low rating it is generally suitable for acne-prone or breakout-prone skin.
One thing to note is that products using this extract may also contain richer emollients or occlusives for texture so always check the full ingredient list if clogged pores are a concern.
Summary
Aspergillus/Prunus Serrulata Flower Ferment Extract conditions the skin and acts as a light emollient. The fermentation process unlocks amino acids, peptides and antioxidants that smooth rough texture, support the moisture barrier and leave a soft silky finish without heaviness.
The ingredient enjoys moderate popularity, especially in Korean and Japanese inspired skincare where fermented botanicals are sought after, yet it is still niche compared with long-standing actives like hyaluronic acid or niacinamide.
Overall safety is high with low irritation and comedogenic risks for most users. As with any new skincare product it is wise to patch test first to confirm personal tolerance.
