Bioferments in Formula of  Personal care Products

The virtues of fermentation within the human body are well known. It is proven good techniques for food, as Kimchi, Sauerkraut, Kefir, Idli & Dosa utilizes this technique. it is also significant for beauty products. The latest trend in Cosmetics particularly Skin Care is fermented beauty products. This concept, originated in Korea, basically involves fermentation of natural ingredients like black tea, ginseng, seaweed, bamboo sap extract, red clove flower, hibiscus, snow lotus and various herbs and flowers.

The cosmetics industry is always looking for innovation, and fermentation products, will likely become the world trend of tomorrow. While mankind has revived the ancient yet scientifically advanced concept of fermentation, it, in turn, can reinvigorate the glow and texture of skin, among other benefits.

Ferments such as probiotics, enzymes, bacteria or yeast have been used in cosmetics for years. Indeed, the enzymes help to maintain our skin microbiome, the cutaneous microbial flora which consists of more than 500 different species of microorganisms that are multiplying every day on our skin.

This variety is crucial in the good balance of the skin and allows it to be better protected against external aggressions. Because, the less varied the skin microbial flora is, the more the unwanted pathologies can settle, including eczema or acne. By forming a protective barrier against external aggressions, inflammation, infections and other skin diseases, the skin microbiome can, in the long term, help the skin to remain better and to be better protected. The microbiome is, indeed, an important part of the skin’s barrier function and plays an essential role in the good health of the epidermis.


A balanced microbiome means that the skin looks healthy, radiant and regenerates itself better. When it’s weak and damaged, it can provoke dryness, sensibility, breakouts and other skin conditions.
In short, the ferments in cosmetics help to stimulate the natural skin defences. They can also be used to purify acne prone skin, to help rebuild the skin barrier of the sensitized skin or to protect the skin from pollution thanks to their antioxidant properties.
Their use has been known for many years in cosmetics, but what is more recent is the use of fermented natural ingredients, not just ferments alone.

Fermented ingredients are gaining a massive following for being more potent, powerful, and super boosting in skin care products.
Bio-fermented products for the cosmetic and personal care applications employs the principles of fermentation, which allows for the isolation and concentration of various phytochemicals. Fermentation has been regarded as both a traditional art and modern science.
Bioavailability of actives is increased by utilizing modern benefits of fermentation. Ingredients that provide increased skin and hair affinity are taking centre stage in the cosmetic industry.


Bio-fermented ingredients incorporated into beauty products can provide increased skin and hair affinity. For cosmetics, fermented ingredients are more symbiotic with the skin and support skin functions without disrupting natural processes making the ingredients less likely to cause sensitivity in skin care applications.

By initiating fermentation, various cosmetic benefits, such as improved bioactive delivery, oxygen uptake, moisturization, and reduction in skin irritation, can be increased and made more readily bioavailable for skin and hair care applications.

Benefit of Fermented ingredients : Indeed, fermenting natural ingredients gives them new properties:
– the fermentation process maintains the integrity of the ingredients.
– a fermented ingredient has a more acidic pH, which has a better affinity with the skin (with its naturally acidic pH),
– the fermentation process transforms the ingredients: during the fermentation, the ferments break down their molecular structure. The fermented ingredients have smaller, Simpler molecules, which allows them to penetrate the skin more deeply and quickly,
– the fermentation adds nutrients such as amino acids and peptides to the ingredient and makes the fermented ingredient richer in antioxidants than its unfermented version,
– the fermented ingredients also have anti-inflammatory properties. Thanks to the fermentation process, they become rich in enzymes, which are able to soothe and prevent skin inflammation. Basically, the enzymes eliminate the “bad bacteria” the skin may contain and replace them with “good bacteria”, this in turn helps to preserve the skin balance.

The use of both types of ingredients, ferments and fermented ingredients has a lot of advantages for the skin because they don’t “work” on the same level. The ferments have an action on the microbial flora of the skin (which is on the surface, in the protective layer of the epidermis) and the fermented ingredients penetrate into the deeper layers of the epidermis and promoting its natural renewal.

PRODUCT WRITE-UP :
This cream with Kopcarotol gives light coverage and soft silky after feel, the skin gets an immediate smoothness and radiance glow.

Formulation efficacy :
The formulation efficacy was determined for antioxidant activity.

The FRAP assay is directly measures antioxidants (or reductants) in a sample compared to other assays measuring inhibition of free radicals.

Antioxidant activity: The formulation efficacy was determined by FRAP (ferric reducing antioxidant power) method. This method relies on the reduction of ferric ion-TPTZ (2,4,6-tri(2-pyridyl)-1,3,5- triazine) by the antioxidants. Thus formed Fe+2-ligand produce intense blue color which is correlated with antioxidant content.
Procedure : One gram of the cream formulation was extracted with 9 ml of 50% methanol, centrifuged and filtered to obtain clear extract. Antioxidant activity of this extract was determined using standard FRAP assay protocol.
