What Is Grifola Frondosa/Ilex Paraguariensis Leaf Extract Ferment Filtrate?
Grifola Frondosa/Ilex Paraguariensis Leaf Extract Ferment Filtrate comes from a blend of yerba mate leaves, known botanically as Ilex paraguariensis, and the maitake mushroom, Grifola frondosa. During production the leaves are first turned into an aqueous extract rich in natural caffeine, polyphenols and minerals. This extract is then fermented with maitake, whose enzymes break large plant molecules into smaller, skin friendly fragments while creating new compounds such as beta glucans and short chain peptides. Once fermentation is complete the mixture is filtered, leaving behind a clear, odorless liquid packed with antioxidants, humectant sugars and conditioning agents.
Yerba mate has long been valued in South America as a stimulating tea, while maitake has a history in East Asian cuisine and traditional wellness. Scientists saw that both plants carry strong antioxidant and moisturizing qualities, and fermentation offered a gentle way to unlock and boost these traits. The resulting filtrate entered cosmetic labs in the past decade as formulators searched for multi tasking botanical actives that fit clean beauty trends.
Because it is water soluble and light in texture, this ingredient slips easily into a range of leave on and rinse off products. It often appears in hydrating serums, sheet masks, anti aging creams, soothing after sun gels, lightweight moisturizers and scalp or hair tonics that aim to protect against free radical stress while keeping skin or strands supple.
Grifola Frondosa/Ilex Paraguariensis Leaf Extract Ferment Filtrate’s Cosmetic Benefits/Uses
In formulations this fermented filtrate pulls triple duty, delivering the following benefits:
- Antioxidant – The polyphenols from yerba mate and beta glucans formed during fermentation help neutralize free radicals. This supports a brighter, more even looking complexion and can help slow the visible signs of premature aging caused by pollution or UV exposure.
- Humectant – Fermentation creates small sugar molecules that draw water into the upper skin layers. This boosts surface hydration, plumps fine lines and improves the glide of creams or gels without leaving a heavy feel.
- Skin Conditioning – The blend of peptides, amino acids and minerals conditions the skin barrier, leaving it feeling soft, smooth and refreshed. It can also enhance product spreadability and overall sensory appeal.
Who Can Use Grifola Frondosa/Ilex Paraguariensis Leaf Extract Ferment Filtrate
This fermented botanical suits most skin types because it is lightweight, water based and non-occlusive. Dry or mature skin benefits from its humectant sugars while oily and combination skin appreciate its quick-absorbing texture that will not clog pores. Sensitive skin generally tolerates the filtrate thanks to its mild pH yet anyone with known allergies to mushrooms or yerba mate should exercise caution.
The ingredient contains no animal-derived substances and the fermentation process relies solely on plant material and a naturally occurring fungus so it is considered vegan and vegetarian friendly.
No data suggest that topical use poses a risk in pregnancy or while breastfeeding. The ingredient stays on the surface of the skin and does not contain retinoids, salicylic acid or hormone-active compounds. However this is not medical advice and anyone pregnant or nursing should have their healthcare provider review all skincare products they plan to use.
The filtrate is not known to increase photosensitivity. Its antioxidant content can in fact support the skin under sun exposure though daily sunscreen is still essential. It layers well with most actives and can be used morning and night without special restrictions.

Rating: 0–1 (essentially non-comedogenic)
Grifola Frondosa/Ilex Paraguariensis Leaf Extract Ferment Filtrate is water based and contains no heavy oils or waxes that might clog pores. Its humectant sugars draw moisture without leaving a greasy film and the fermentation step breaks large molecules into lightweight fragments that rinse or absorb cleanly. All of this keeps the risk of follicular blockage extremely low
The filtrate is therefore considered suitable for acne prone or easily congested skin
In most formulas it is used at modest levels and sits alongside other watery actives so the overall breakout risk depends more on the companion ingredients than on the filtrate itself
