5. Vitamin K
This vitamin plays a crucial role in the process of blood clotting. In addition, it helps reduce the appearance of dark circles and bruising by strengthening the walls of blood vessels and capillaries. Strengthened blood vessel walls help prevent blood leakage, which can cause discolouration and bruising under the eyes. Vitamin K has anti-inflammatory properties, which can help reduce skin redness and irritation.
6. Biotin
Also known as vitamin B7, biotin is crucial in promoting the growth and maintenance of skin, hair, and nail tissues by supporting keratin production. This protein is a major component of hair, skin, and nails.
Biotin, is often included in topical skincare products and hair care supplements. When applied topically, biotin may help improve skin hydration and increase the production of ceramides — lipids that help maintain the skin barrier. It also helps reduce inflammation and improve the appearance of fine lines and wrinkles.
In addition to topical application, you can take biotin orally as a supplement or through dietary sources such as eggs, nuts, and leafy green vegetables.
