What Is Lactobacillus/Broccoli Extract Ferment Filtrate?
Lactobacillus/Broccoli Extract Ferment Filtrate is made when broccoli extract, taken from the edible florets of Brassica oleracea italica, is fermented with the friendly bacterium Lactobacillus. During fermentation the bacteria break down large plant molecules into smaller compounds and release peptides, amino acids and antioxidants. Once fermentation is complete the mixture is filtered, leaving behind a clear liquid packed with skin-loving nutrients.
Fermented plant ingredients rose to popularity in Korean skin care, where beauty chemists noticed that the by-products of fermentation could make formulas gentler and more effective. Since then this filtrate has found its way into a range of global cosmetic products.
The ingredient is commonly mixed into hydrating toners, essence-style serums, sheet masks, lightweight moisturizers and soothing after-sun gels. Brands like it because it is water soluble, easy to add at cool temperatures and compatible with both natural and lab-made actives.
Lactobacillus/Broccoli Extract Ferment Filtrate’s Cosmetic Benefits/Uses
In skin care formulas Lactobacillus/Broccoli Extract Ferment Filtrate serves a single main role.
Skin conditioning: The filtrate helps keep skin soft, smooth and balanced. Its blend of amino acids and antioxidants supports the skin barrier, attracts moisture and can calm the look of temporary redness, leaving the complexion feeling nourished and comfortable.
Who Can Use Lactobacillus/Broccoli Extract Ferment Filtrate
This ingredient is generally well tolerated by all skin types, including dry, combination, oily and even reactive or sensitized complexions. The lightweight water base and soothing properties make it unlikely to clog pores or leave a greasy film, so acne-prone users can enjoy it as well. No specific skin type is considered unsuitable, though anyone with a known sensitivity to broccoli or fermented plant extracts should proceed with caution.
Because it is produced from broccoli and a probiotic bacterium, with no animal-derived additives, it is appropriate for vegans and vegetarians.
Current safety data suggest it can be used during pregnancy and while breastfeeding, however this is not medical advice. Expectant or nursing mothers should review any skin care product with their physician to ensure it fits their individual needs.
The filtrate does not contain ingredients known to increase photosensitivity, so it will not make skin more prone to sunburn. Standard daily sunscreen use is still recommended for overall skin health.
Potential Side Effects/Adverse Reactions
Responses to topical Lactobacillus/Broccoli Extract Ferment Filtrate differ from person to person. The effects listed below are possible but unlikely for the average user when the ingredient is properly formulated and preserved.
- Temporary redness or stinging – most often linked to very sensitive or compromised skin barriers
- Mild itching – can occur if the individual is sensitive to fermented plant compounds
- Allergic contact dermatitis – rare but possible in those with allergies to cruciferous vegetables or certain preservatives used alongside the filtrate
- Breakouts – unusual and usually due to other comedogenic ingredients in the same product rather than the filtrate itself
If any uncomfortable reaction develops stop using the product and consult a qualified skin care professional or medical provider.
Comedogenic Rating
Rating: 0/5
Lactobacillus/Broccoli Extract Ferment Filtrate is water based, lightweight and free of heavy oils or waxes that could block pores. Its small fermented molecules are quickly absorbed and do not sit on the skin surface, which keeps the risk of congestion extremely low.
Suitable for acne-prone or breakout-prone skin.
No data suggest the filtrate interferes with common acne treatments such as salicylic acid or benzoyl peroxide, so it can be layered alongside them without issue.
Summary
Lactobacillus/Broccoli Extract Ferment Filtrate is a skin conditioning agent that softens, hydrates and calms the complexion. Fermentation breaks broccoli extract into amino acids, peptides and antioxidants that attract water, support the skin barrier and soothe visible redness.
While not yet a household name it has a growing fan base in K-beauty inspired toners, essences and masks because it offers gentle results without heaviness.
Current research and real-world use point to a high safety profile with very low irritation or comedogenic risk. As with any new skincare ingredient a simple patch test is wise before full-face application.
