Detailed answer

Toners are primarily used for balancing the pH of the skin and removing any remaining impurities after cleansing. They are not designed to tighten or firm the skin. To address sagging skin on the legs, it is recommended to focus on exercises that target the legs and to use specialized skincare products that contain ingredients like retinol, hyaluronic acid, and peptides, which can help improve skin elasticity. Additionally, maintaining a healthy lifestyle with a balanced diet, regular hydration, and protecting the skin from sun damage can also contribute to better skin tone and firmness.
