Skincare Guide - Quercetin
Quercetin in skincare
Quercetin is a natural plant compound belonging to the flavonoid group, found in many fruits, leaves, and flowers. Apples, onions, grapes, and green tea are particularly rich in quercetin. In skincare, it is valued for its strong antioxidant and anti-inflammatory properties, which help protect the skin from oxidative stress and premature aging.
What makes quercetin so special?
Quercetin acts as a so-called free radical scavenger: It neutralizes free radicals that are generated by UV radiation, pollution, or stress. These free radicals can damage skin cells and break down collagen structures, leading to wrinkles and loss of elasticity. Quercetin protects the cells and strengthens the skin's natural defense mechanisms ( healthline.com ).
Effect on the skin barrier
Studies show that quercetin can lower inflammatory markers in the skin and promote the regeneration of damaged skin cells. It stabilizes the lipid structures in the stratum corneum, thus contributing to a healthy skin barrier. Its soothing effect also makes this ingredient interesting for sensitive or stressed skin types ( PubMed ).
Anti-aging properties
Due to its antioxidant activity, quercetin protects the collagen and elastin network of the skin and can thus prevent skin aging. This effect is enhanced when combined with vitamins C and E or plant oils, as the antioxidants regenerate and stabilize each other ( dermasence.de ).
Use in cosmetic products
Quercetin is primarily found in serums, creams, and after-sun formulations. It is ideally suited for skincare products that aim to regenerate, protect, and soothe. Especially for sensitive or irritated skin, quercetin can help reduce redness and strengthen its resilience.
In combination with NATURFACTOR® care
NATURFACTOR®'s Blue Crystal Drops facial oil combines antioxidant plant extracts with high-quality lipids to neutralize free radicals and strengthen the skin barrier. Quercetin-rich botanicals are a key component of the protective formula – ideal for regenerated, supple skin overnight.
Conclusion
Quercetin is a versatile, plant-based active ingredient that protects the skin from oxidative stress, reduces inflammation, and supports natural regeneration. Its antioxidant power makes it a valuable component of modern anti-aging skincare – especially in combination with other plant-based antioxidants and lipids.
