Beauty supplements effective for skin hair nails

A medical study explains that beauty supplements, such as collagen, biotin, and hyaluronic acid, generally offer limited benefits, especially for individuals with nutritional deficiencies or those advancing in age. It indicates that scientific evidence supports the effectiveness of collagen in improving skin elasticity, hydration, and reducing fine lines when used regularly over several months. However, the benefits of antioxidants and biotin are not clearly evident unless there is a true deficiency. The doctor emphasizes the importance of a healthy, fundamental lifestyle and affirms that beauty supplements are not a substitute for a balanced diet or external skincare products. She also advises caution against excessive dosages and stresses the need to ensure product quality.
