SHIUNKO FERMENTED OIL

Shiunko Fermented Oil  is an advanced skincare ingredient derived from the traditional Japanese herb Lithospermum erythrorhizon, also known as red-root gromwell or redroot lithospermum. This plant has been a key component in Kampo, traditional Japanese medicine, where its roots are utilized for their potent skin-healing properties. Historically, boiled Shiunko roots were combined with other herbs like Angelica root to address a variety of skin conditions, such as burns, frostbite, eczema, psoriasis, and general skin irritations. This practice traces back to the Eastern medicine principles described in ancient Chinese and Japanese texts.

The modern adaptation, Shiunko Fermented Oil, undergoes a specialized fermentation process, enhancing both its texture and efficacy compared to conventional oils. The roots are harvested, dried, and then soaked in plant oils, followed by fermentation. This process amplifies the active compounds, including Shikonin and its derivatives (e.g., acetylshikonin and isobutyroylshikonin), which are naphthoquinone compounds known for their anti-inflammatory, anti-tumor, and angiogenesis-inhibiting effects. Research highlights that Shikonin can hinder the proliferation of endothelial cells and reduce melanoma-related angiogenesis, making it valuable for skin regeneration.

In LAST skincare, Shiunko Fermentoil promotes fibroblast proliferation, improving wound healing and skin repair. Its fermentation process also boosts the compound’s ability to inhibit melanin production, offering a mild skin-brightening effect (with a 15% reduction in melanogenesis at just 0.1% concentration). It additionally enhances blood circulation and has been clinically shown to improve skin texture, making it an effective solution for addressing skin concerns like aging, pigmentation, and dryness.
