The nasolabial folds, medically known as “nasolabial folds”, are a furrow-like line located on the outside of the nose towards the upper lip. Many people may not be aware that from infancy to old age, the frown line remains with us throughout our lives. As we grow older, the lines get progressively worse. Therefore, deep lines are seen as a sign of old age. On the other hand, since all babies have lines, they can only be reduced to a certain extent but not completely eliminated. Hyaluronic acid rejuvenation is nothing new, so what is the role of hyaluronic acid in reducing the lines? First of all, hyaluronic acid can have a very good supporting effect, “piling” under the sagging skin, just like the cement column of a building, which can support the sagging nasolabial folds. Secondly, the water retention effect of hyaluronic acid is also good for the improvement of wrinkles. I am going to share my case with you. In addition, certain nasolabial folds are associated with overactive muscles that lift the lips, and combined Botox treatment has good results for such candidates.
