What is 「GREEN COCOONS MIDORI-MAYU」
Green cocoons Midori-mayu are cocoons that are formed naturally by genetic changes where the green colour of mulberry leaves is extracted.
Green cocoons contain more than 10 times the flavonoids of regular cocoons, and are therefore hailed for their antioxidant and UV protection properties.
It is known as "the kind of silk that is better than silk" because of its beauty benefits over white cocoons. It is one of the rarest and highest quality beauty ingredients in the world.
Contains flavonoids, an active cosmetic ingredient with excellent antioxidant, anti- ageing and anti-inflammatory properties *10 times more than white cocoon
Contains Collagen Silk, a skincare ingredient made up of 18 amino acids which is closest to the human skin *1.6 times more than white cocoon
Effectively reduces UVA and UVB rays (traditional cocoon only blocks out the UVB ray) *Applicable to the “Green Cocoons Midori Mayu” characteristics researched and developed by &PREMIUM & Japanese laboratories
Natural ingredients, subtle to the skin without causing any irritation
Explore the Science of Midorisilk™
Midorisilk™ is made from the cocoons of “Green Cocoons” – also known as “Midori Mayu” in Japanese. Its main active ingredient, a viscous gel-like protein supramolecule called “Sericin” , is scientifically well-known for its affinity to human skin.
Sericin a kind of protein very similar to human skin, creates a second layer of protection for the skin.
The Midorisilk™️ ingredient in &PREMIUM products contains rich Sericin, which has a very similar structure to the Natural Moisturizing Factor (NMF) found on the surface of the skin. Due to their affinity, Sericin is highly effective in hydrating and moisturizing the skin, making it more healthy and resilient without burdening it.

Fibroin: Widely used by medical professionals in healing wounds and repairing skin
Silk fiber consists primarily of two proteins: sericin, which accounts for approximately 25% of the fiber, and fibroin, which accounts for approximately 75%. Fibroin is widely regarded as a miracle molecule in the medical community because of how remarkably effective it is in healing wounds, treating burns, and repairing skin tissue. For years, scientists have been studying its potential applications in medicine.
So far, the use of sericin in skincare products has been limited. Experts have faced many technical challenges in the process of developing highly concentrated and effective skincare products using sericin as it is made of thick and viscous molecules.
Together with researchers from a professional laboratory in Japan and under the supervision of Professor Takayuki Nagashima of the Faculty of Agriculture at Tokyo University of Agriculture, we have successfully discovered an effective form of the sericin protein that has the ideal molecular weight. It has powerful and miraculous reparative effects on aging and damaged skin. By combining it with skincare ingredients derived from Chinese, Western, and Japanese medicinal herbs, we have successfully developed Midorisilk™. With the highest sericin concentration among all skincare products, Midorisilk™ is a result of &PREMIUM's core breakthrough technology.
Flavonoids – the miraculous gold-like greenish-yellow substance that delay skin ageing
Flavonoids are powerful antioxidants found in sericin and are renowned for their anti-ageing effects on skin. The most relevant property of flavonoids is their ability to absorb ultraviolet (UV) rays (both “UV-A” and “UV-B”) and inhibit melanin production. In particular, they prevent “UV-A” from reaching dermis, the inner layer of the skin, and causing signs of skin ageing like wrinkles and sagging. By blocking harmful UV rays, they rejuvenate the skin and erase visible traces of age. Studies have shown that green cocoons contain over 10 times more flavonoids than white cocoons do.
From Tokamachi City, Niigata Prefecture, Japan's "Hometown of Silk"
Our main ingredient "Green Cocoon Midori Mayu" comes from Tokamachi City, Niigata Prefecture, Japan, a naturally rich "silk town". Blessed with nature, Tokamachi is known as one of the areas with the heaviest snowfall in Japan. Due to heavy snow and high humidity, the region has long produced high-quality silk fabrics.
The world's first large-scale aseptic factory production
In order to complete the high-purity and high-quality "Green Cocoon Midori Mayu", the Japanese factory is a sterile production, and the hygienic standard has reached the level of a professional laboratory. The factory's production technology can detect 1/10 or less bacteria in the water, so under this extremely high-safety aseptic production, our products do not contain any parabens, phenoxyethanol, without any preservative added.
Six Magical Powers of Midori-Mayu
Silk sericin turns on the cellular clockwork that stimulates the natural production of collagen, thereby increasing skin's plumpness, elasticity and diminishing the appearance of fine lines and wrinkles.
Sericin improves the flow of blood through the layers of the skin by encouraging angiogenesis; the process by which new blood vessels form and grow to increase the delivery of nutrients.
Sericin reduces skin's tendency to be inflamed and irritated by working to significantly reduce the amount of inflammatory molecules produced naturally in the skin.
Sericin deeply hydrates and moisturises skin by mimicking NMF (Natural Moisturizing Factor) and forming a skin barrier that reduces TEWL (Trans-Epidermal Water Loss).
Sericin helps reduce the tendency to form scars by regulating Transforming Growth Factors (TGF) β1 and β3 which are strongly linked to scar formation.
Sericin improves the rate of tissue healing by recruiting specialised repairing stem cells known as Mesenchymal Stem Cells to sites of injured or damaged skin.
