Coenzyme Q10, also known as ubiquinone, is a powerful antioxidant that is commonly used in cosmetic and skincare products. It helps to protect the skin from environmental stressors and free radicals, while also promoting healthy-looking skin. Coenzyme Q10 is often included in anti-aging creams and serums to reduce the appearance of fine lines and wrinkles, and it can also be used in hair care products to promote healthy hair growth.
