    VI20 is a newly upgraded high-quality bioactive peptide developed for premium cosmetic formula innovation and modern standardized skincare industrial production. Adopting advanced bionic synthesis technology and multi-stage low-temperature purification and lyophilization craftsmanship, this premium raw material features a stable molecular structure, high activity purity and excellent water solubility. All production procedures follow strict industrial quality management standards. Each batch of VI20 undergoes rigorous impurity screening, activity stabilization and comprehensive performance testing, ensuring stable batch consistency and outstanding biological safety. With superior skin affinity and flexible formula adaptability, it fully meets the global skincare market’s demand for mild, stable and long-acting innovative functional ingredients.
    The core advantage of VI20 lies in its gentle and efficient skin microenvironment regulating performance. Daily skin is inevitably affected by various external stresses, including dry climate, ultraviolet exposure, urban pollutants and seasonal environmental changes. Long-term cumulative metabolic pressure and continuous external interference often lead to rough skin texture, dull complexion, uneven skin tone and reduced skin vitality. As a finely optimized peptide active substance, VI20 can gently balance cutaneous metabolic circulation, relieve persistent oxidative burden on skin tissues, and effectively improve fatigued and lifeless skin conditions. Different from conventional single-function ingredients that only provide temporary surface improvement, it focuses on long-term gradual conditioning to refine uneven skin texture, enhance skin transparency and restore the skin’s natural delicate and luminous state.
    In daily skin barrier maintenance and delicate skin care, VI20 delivers remarkable comprehensive skincare effects. It can efficiently replenish skin moisture and form a lightweight, breathable protective film on the skin surface to achieve long-lasting moisture locking, alleviating common skin problems such as dryness, tightness and flakiness. Meanwhile, rich skin-friendly active components help stabilize the skin’s natural barrier structure, strengthen skin tolerance against external irritation and environmental fluctuations, and soothe subtle skin discomfort. Featuring ultra-mild, low-sensitivity and non-irritating properties, VI20 is highly adaptable to all skin types, especially sensitive and fragile skin with weak self-regulation ability.
    VI20 boasts excellent formula compatibility and wide application versatility. It can be seamlessly integrated into brightening essences, moisturizing lotions, barrier repair creams and various high-end daily skincare products. It can be freely compounded with most conventional cosmetic active ingredients without causing product stratification, discoloration or activity attenuation. Supported by complete qualification test reports and stable long-term supply capacity, VI20 has become a trusted innovative peptide raw material for skincare brands focusing on scientific, mild and sustainable skin maintenance.
