The repeated movement of the forehead muscles, necessary for a wide array of facial expressions, creates lines on the skin that are initially visible only when the muscles are in contraction. As the skin loses its elasticity, due to ageing, sun damage, smoking and other factors, the lines become permanent and form deep furrows on the forehead.
There are certain non-invasive cosmetic procedures available which can soften the hard expression caused by forehead lines by reducing the deep wrinkles and smoothing the skin, thus offering a subtle yet fresh look.
The suitable treatment for you depends on several factors, such as the specific type of your wrinkles, whether they are static or dynamic, your skin type, the specific area affected, your age, medical history etc.
