![]() It is a tyrosinase (an enzyme that controls the production of melanin) inhibitor, but not as effective as other tyrosinase inhibitors like licorice extract. ![]() The other half of sake worth discussing, koji (kojic acid) is a skin-lightening agent and antioxidant. The yeast is credited with promoting good skin condition and is frequently found in products that reduce redness. It is obtained through the fermentation of saccharomyces - a genus of fungi that is known as the baker's yeast - in the presence of metal ions. Thus, these kinds of evaluations are very important in cosmetics development to evaluate the best risk and benefit correlation."¹Īnother fungi ferment, saccharomyces ferment, has similar benefits. Only formulations containing SC had long term effects in the improvement of SMR. ![]() "Our results suggest that vitamins and SCE showed effects in SM and SMR. The subjects were then tested for transepidermal water loss (TEWL), skin moisture (SM), skin microrelief (SMR), and free radical protection in 3 hour, 15 days, and 30 day intervals. One contained SCE, and/or vitamins A, C, and E, and was patch-tested on the back of volunteers. In one study, saccharomyces cerevisiae extract (SCE) was studied in several formulations. Saccharomyces cerevisiae is a species of yeast used for brewing beer. ![]() While these studies are minimal, we may be able to glean some deeper understanding into the benefits of sake by examining two of the most popular (and more studied) ferments as well as koji (kojic acid) itself. It's important to note that the first study I mentioned comes from Doosan Group R&D, which seems primarily interested in vehicles, construction, electrical, etc., while the second study was paid for by AMOREPACIFIC R&D - a popular skincare company. Additionally, "laminin 5 also accelerates the assembly of basement membranes and may enhance the recovery of damaged skin."⁵In the same study, experiments were done on hairless mice (in vivo) and showed that topical application protected the mouse from photo-aging.Īnother study showed *that sake extract inhibited tyrosinase, both in vivo (in a living organism) and in vitro, though it is unclear how many subjects were involved based on the abstract alone.⁶ One in vitro (meaning in a dish or tube) study showed that rice wine increased "the expression of procollagen and laminin-5,"⁴ which is one of the key components in the intercellular makeup of the layer that holds the epidermis to the dermis. Ferments have been all the rage recently, with Saccharomyces cerevisiae (living yeast) extract and Saccharomyces ferment being the two I see the most.Ī couple of studies on sake (specifically rice wine and sake extract) showed multiple benefits. Sake is a fermented product made from rice, water, koji, and yeast. I've highlighted the ingredients that are worth discussing a bit in detail. This is a bit of a review slash ingredient breakdown, so I hope you enjoy!įull Ingredients: Water, Glycerin, Butylene Glycol, Rice Ferment Filtrate (Sake), Glutamic Acid, Arginine, Leucine, Ceramide 3, Ceramide 6, Placental Protein, Arbutin, Dipotassium Glycyrrhizate (Licorice Root Extract), Glycine Soja (Soybean) Protein, Maltitol, Methyl Gluceth-10, Peg-6 Hydrogenated Castor Oil, Hydroxyethylcellulose, Sodium Styrene/Acrylates Copolymer, Citric Acid, Sodium Citrate, Phenoxyethanol, Methylparaben, Fragrance. I originally posted it in r/AsianBeauty where I got some excellent feedback and thoughts. Someone requested more reviews and breakdowns, so I figured I would post this here.
