What is Isoquercitrin
Isoquercitrin is a high-activity natural flavonoid glycoside compound extracted from natural plants such as ginkgo leaves, bidens bipinnata and hawthorn. It features superior bioavailability and low toxicity compared with common flavonoid ingredients. Widely applied in high-end cosmetics, functional health foods and pharmaceutical fields, it possesses powerful antioxidant, anti-inflammatory, barrier repairing and immune regulating activities. It is a premium natural active ingredient with dual values of skin beauty care and human health regulation.
What are Main Components of Isoquercitrin
Isoquercitrin is a high-purity single-component flavonoid glycoside extract with stable molecular structure and clear efficacy:
Isoquercitrin: The exclusive core active substance of the product, undertaking all core functions including antioxidant, anti-inflammatory, skin barrier repair and metabolic regulation, which is the key source of all product efficacy.
Trace natural flavonoid homologs: Ultra-trace natural plant-derived components retained during deep purification, which synergistically enhance the biological activity of the main ingredient without affecting product purity and safety.
What are the benefits of Isoquercitrin
Isoquercitrin is a multi-functional high-bioavailability active ingredient with a wide range of physiological
Core Cosmetic & Skin
-
- High-Efficiency Antioxidation & Anti-Photoaging
It activates the body’s Nrf2 antioxidant pathway, efficiently scavenges skin free radicals, resists UV-induced photoaging and environmental oxidative damage, reduces fine lines and skin relaxation, and maintains long-term youthful skin condition. - Skin Barrier Strengthening & Moisturizing
It significantly reduces transepidermal water loss, locks skin moisture efficiently, repairs damaged keratin barrier, relieves dry, rough and tight skin, and improves overall skin hydration and resilience. - Anti-Inflammatory & Sensitive Skin Stabilizing
It inhibits NF-κB inflammatory pathway activation, reduces mild skin inflammation, redness and sensitivity, calms irritated skin, and provides gentle and stable maintenance for fragile and sensitive skin. - Skin Brightening & Dullness Improvement
It inhibits abnormal melanin aggregation and deposition, improves facial dullness, sallow complexion and uneven skin tone, brightens skin transparency, and makes skin clear and luminous. - Collagen Regeneration & Anti-Aging
It promotes skin collagen synthesis and angiogenesis, delays skin tissue aging, improves skin elasticity, and fades dry lines and fine lines caused by aging and dryness.
- High-Efficiency Antioxidation & Anti-Photoaging
Health Food & Pharmaceutical Functions
-
- Systemic Antioxidant & Anti-Aging
With high bioavailability, it neutralizes internal harmful free radicals, reduces systemic oxidative stress damage, protects cell vitality, and delays bodily aging. - Immune & Metabolic Regulation
It regulates human immune response, enhances body defense capability, assists in lipid and glucose metabolism balance, and improves sub-health state. - Cardiovascular & Hepatic Protection
Modern studies prove that it assists in protecting cardiovascular health, alleviates liver oxidative damage, and maintains normal visceral physiological functions. - Respiratory & Seasonal Comfort Support
It relieves mild respiratory discomfort, supports respiratory tract health, and helps the body adapt to seasonal environmental changes.
- Systemic Antioxidant & Anti-Aging
