Fermentation Science

VINBIOME™ Complex
Based on rigorous scientific research, we have carefully selected proven and effective skincare ingredients and have had Hanega’s artisans ferment them to develop proprietary vinegar-fermented extracts that have higher concentrations of absorbable actives for enhanced effectiveness. As we value balanced skin wellness, we have combined our proprietary vinegar-fermented extracts with our proprietary aged vinegars, our Probiotics Complex and our Prebiotics Complex to create a holistic VINBIOME™ Complex that helps to promote a healthy skin microbiome and sustainable skin “prejuvenation”.

VinB10-Biotic™ Ginseng(Hydrolyzed Ginseng Saponins)
For generations, the artisans of Hanega have fermented vinegar with ginseng root for Traditional Asian Medicine doctors, who used these vinegars to make traditional medicine. Panax ginseng root is often known for having large amounts of unique saponins called ginsenosides, such as Rg1, Rg3, Rg5, Rh1, Rh4 and Rk1, which are beneficial for health and wellness. The long and meticulous fermentation process of aged vinegar further breaks down these unique saponins to more variety and more easily absorbable ginsenosides. Our proprietary VinB10-Biotic™ Ginseng is fermented with 10-year black vinegar and further refined into a multi-functional ingredient that helps to firm and soothe the skin.

VinB10-Biotic™ Wheat(Triticum Aestivum (Wheat) Seed Extract)
One of the most important ingredients for aged vinegar is a Korean fermentation starter called “nuruk”, which is a mold of wheat that is naturally fermented with various microorganisms and enzymes. “Nuruk” has a rich concentration of polysaccharides that are beneficial to skin health. In collaboration with Hanega’s artisans, we have found the optimal fermentation and refining process to break down these wheat polysaccharides into the most effective form for skincare formulations. Our proprietary VinB10-Biotic™ Wheat is fermented with 10-year black vinegar and further refined into a multi-functional ingredient that helps to firm and soothe the skin.

VIN-B10™
VIN-B10 is 107’s proprietary vinegar ingredient processed from Hanega’s 10-year black vinegar with 35+ beneficial nutrients such as amino acids, organic acids, minerals and vitamins. This premium aged vinegar contains more vitamins, such as vitamin A, B5, C and D, that help to brighten and hydrate skin. The Hanega artisans source the organic rice used in this premium aged vinegar from trusted rice grain farmers from all around Korea.

Probiotics Complex
Hanega’s artisans care deeply about their proprietary probiotic cultures. They nurture their probiotics as if they were their own children. They feed their probiotics with the best herbs and naturally-sourced foods, and they even put on traditional Korean folk songs to provide a calm environment for the probiotics to grow. And they never, ever, enter the storing room when they themselves are not in a good emotional mood. The artisans take this much care for their probiotics because they know that effective fermentation of the probiotics culture is critical to producing abundant and balanced postbiotics.
At 107, we similarly value the harmony and wellness of the skin’s microbiome, as any imbalance can cause various skin challenges. We have researched the skin microbiome and selected key probiotic strains that can help make the skin’s microbiome more balanced and healthier. Our Probiotic Complex consists of selective probiotic ingredients such as Lactobacillus Ferment (Lactobacillus Plantarum, Lactobacillus Johnsonii, Lactobacillus Rhamnosus, Lactobacillus Acidophilus and Lactobacillus Reuteri), Lactococcus Ferment (Lactococcus Lactis), Bifida Ferment Lysate (Bifidobacterium Longum) and Streptococcus Thermophilus Ferment (Streptococcus Thermophilus).

Prebiotics Complex
Microorganisms and probiotics on the skin’s microbiome need “food”, or prebiotics, to be healthy and functional. Based on our research, we have selected key prebiotics ingredients that can help provide sustenance for the skin’s microbiome. Our Prebiotic Complex consists of proven prebiotic ingredients such as Xylitol, Rhamnose, Fructooligosaccharides and Inulin.

Modern Science

Ethyl Ascorbic Acid
Ethyl Ascorbic Acid Vitamin C, or L-ascorbic acid, has outstanding antioxidant properties and helps to protect the skin from external oxidative stress factors while also helping to firm and brighten the skin. However, this potent ingredient is often unstable and oxidizes easily in formulations, less absorbable to some parts of skin given its hydrophilic characteristics and can cause some irritation to sensitive skin. Given our commitment for worry-free use, we have meticulously selected to include an alternative ethyl ascorbic acid, also known as 3-O-ethyl-L-ascorbic acid. This potent vitamin C derivative ingredient has a similar molecular size as L-ascorbic acid, which helps to better maintain its potency, while being much more stable and less oxidative than L-ascorbic acid and other vitamin C derivatives. It is less irritating to skin, even for sensitive skin, and also better penetrates deeper parts of skin given it is soluble in both water and oil, as opposed to L-ascorbic acid being hydrophilic and more difficult to pass skin’s hydrophobic layers. Our soseo VINBIOME Vitamin C Serum contains 15% of ethyl ascorbic acid for optimal effectiveness and comfortable worry-free use, even for sensitive skin.

Based on an independent clinical study of 22 women from 20-40 years of age and after two weeks of daily use:
- Production of the antioxidant enzyme (catalase) in skin increased by 33.09%

Based on an independent clinical study of 21 women from 40-61 years of age:
- Skin wrinkles decreased by 9.03% after two weeks and decreased by 12.84% after 4 weeks of daily use
- Skin density improved by 4.36% after two weeks and increased by 12.10% after 4 weeks of daily use
- Skin moisture improved by 105.47% after one-time use and increased by 46.67% after 2 weeks of daily use

Worry-Free Use:

107 is committed to making clean, effective skincare products that can be used daily and without worry.

Based on an independently conducted Human Repeat Insult Patch Test(HRIPT) clinical study containing 53 subjects (ranging from 18-61 years old), our soseo VINBIOME Vitamin C Serum showed no indication of a potential to elicit dermal irritation or sensitization (contact allergy).

Based on an independent clinical study containing 30 subjects (ranging from 18-75 years old) by Dermatest GmbH, this product, from a dermatologist point of view, does not exhibit a high irritative potential and, if used as intended, will not lead to undesirable skin reactions.

Environmental sustainability is very important mission for 107. Our soseo VINBIOME Vitamin C Serum is produced with environmentally friendly glass containers and formulations are produced meeting the PETA Cruelty Free Standards.
