What Is Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate?
Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate is a liquid obtained after fermenting rose stem cell cultures with the friendly bacteria Lactobacillus, then filtering the mixture to keep only the active broth. The starting material comes from callus cells of the Damask rose, a hardy cell culture grown in a lab rather than picked from the flower itself. These callus cells are rich in plant metabolites such as polyphenols, flavonoids and natural sugars. When Lactobacillus ferments the extract, it breaks down large molecules into smaller ones, releases additional peptides and produces organic acids that can benefit skin care. This marriage of botanical science and microbiology first gained traction in Korea where brands were looking for gentle yet potent alternatives to traditional plant extracts. Today the filtrate turns up in hydrating essences, calming toners, sheet masks, anti aging serums and protective day creams because it delivers antioxidant power without heaviness.
Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate’s Cosmetic Benefits/Uses
This fermented rose filtrate supports skin on several fronts:
- Antimicrobial – Helps keep formula spoilage at bay and can reduce the growth of surface bacteria on the skin, supporting a clearer complexion
- Antioxidant – Supplies polyphenols and fermentation byproducts that neutralize free radicals, helping to minimize signs of premature aging such as dullness and fine lines
- Skin protecting – Forms a lightweight shield that reinforces the skin barrier, improving resilience against daily environmental stressors while boosting overall hydration
This fermented rose filtrate is lightweight and water based so it typically suits all skin types including dry, oily, combination and sensitive. Its barrier supporting qualities make it especially helpful for skin that feels fragile or easily flushed. There are no ingredients in its production that tend to clog pores so acne-prone users generally tolerate it well.
The material is produced from plant cell cultures and a probiotic strain grown on vegetable media. No animal derivatives are involved which makes it appropriate for vegans and vegetarians.
Current research shows no specific risks for pregnant or breastfeeding women when the ingredient is used in leave-on skincare at standard cosmetic concentrations. Still this is not medical advice and anyone who is expecting or nursing should run their full routine past a qualified doctor to be safe.
The filtrate does not increase photosensitivity so it can be applied morning or night without raising the risk of sunburn, though daily sunscreen remains important for overall skin health.
Potential Side Effects/Adverse Reactions
Side effects from topical use of Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate vary from person to person. The points below describe potential reactions yet most users will not experience them when the ingredient is formulated and used correctly.
- Temporary redness or warmth
- Mild stinging on very compromised or freshly exfoliated skin
- Allergic contact dermatitis in individuals sensitive to rose components or fermentation byproducts
- Rare breakout flare in those highly reactive to new water based actives
If any of the above occur discontinue use and seek advice from a healthcare professional or dermatologist.
Comedogenic Rating
Rating: 0 / 5
Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate is water based, light in texture and contains no heavy oils or waxes that typically block pores. Fermentation further reduces molecule size making it easier for the skin to absorb without leaving residue. No data or anecdotal reports suggest it triggers comedones so it earns the lowest possible rating.
Suitable for acne-prone and breakout-prone skin.
Because it is usually included at modest percentages and combined with gentle humectants or soothing agents, the overall formula it appears in tends to stay low on the comedogenic scale as well.
Summary
Lactobacillus/Rosa Damascena Callus Extract Ferment Extract Filtrate acts as an antimicrobial, antioxidant and protective agent. The probiotic fermentation yields organic acids and peptides that curb surface bacteria, rose polyphenols mop up free radicals and the resulting broth helps reinforce the skin barrier so moisture stays put.
First popularized by Korean skin care the ingredient is still something of a niche star elsewhere but its gentle profile and multitasking benefits are winning it a place in more toners, essences and serums every season.
Current research and cosmetic use history point to a high level of safety for topical application. As with any new ingredient a quick patch test on clean skin is a smart precaution before adding a full-size product to your routine.
