Due to its unique biological effects and natural origin, quercetin is becoming increasingly popular in the cosmetics industry, providing a feeling of freshness and youthfulness to our skin.

Security Information

This flavonoid, derived from natural sources, is known for its safety and tolerance. However, as with any cosmetic ingredient, some individuals may experience allergic reactions or sensitivity. It has been recorded that certain individuals may experience skin irritation, itching, or redness, especially those who are sensitive to flavonoids. For this reason, it is recommended to perform a patch test before using products containing quercetin. Regulatory authorities, such as the European Cosmetics Directive, have recognized this ingredient as safe for use in cosmetic products, but consumers should pay attention to product composition and follow the recommended usage guidelines. It is important to choose reliable manufacturers who ensure ingredient quality and transparency. Quercetin is an excellent choice for those seeking natural skincare, but it is always worth monitoring your skin’s reactions and consulting with professionals if you have any doubts.

Sustainability and Extraction

Quercetin, as a natural flavonoid, can be obtained from various plants, but its production has its own ecological and social aspects. Growing plants for quercetin-containing crops can have a positive impact on soil quality and biodiversity, but intensive agricultural practices can lead to soil erosion and ecosystem disruption. It is important to ensure that quercetin is obtained from sustainably managed farms that take into account biodiversity and ecosystem conservation. From a social perspective, quercetin extraction can provide opportunities for local communities, but it is essential to ensure that workers are paid fair wages and provided with safe working conditions. Therefore, when choosing products containing quercetin, it is important to consider the sustainability and ethical standards of the supply chain. This flavonoid, found in natural plant structures, has excellent potential not only in cosmetics but also in the food industry. Quercetin provides an intense range of colors, making it useful as a natural dye, contributing to aesthetic appearance. In addition, it is an excellent antioxidant, helping to reduce oxidative stress on both the skin and the body as a whole. It can also promote blood circulation, which is especially beneficial for maintaining skin tone and elasticity. In addition to its benefits, quercetin can also be an excellent ally in the fight against inflammatory processes, which is why it is often included in formulas for sensitive or problematic skin. Its versatile application provides opportunities to create innovative products that not only meet beauty standards but also contribute to overall well-being.

Products

Currently, quercetin is found in various cosmetic products, especially skincare products designed to combat aging and improve skin tone. For example, popular serums and creams from South Korea, such as Innisfree’s Green Tea Seed Serum or Missha’s Time Revolution Night Repair serum, may contain this ingredient to enhance skin protection and give it radiance.
