        Hyaluronic acid is being used for the treatment of wrinkles or folds in 
        the aesthetic field. This product is also used for depressive scars. As 
        the underlying subcutaneous scar causes the epidermis to contract, prior 
        to treatment, the contracture needs to be released with a needle that is 
        then used for injection. However, depressive scar is not a common 
        condition in scar treatment. Therefore, the opportunity to treat them is 
        few. In this article, the author proposed the application of hyaluronic 
        acid for the treatment of post-operative scar or deformity of cleft lip 
        patients. As the hyaluronic acid injection requires that the patient has 
        no down-time, it is suitable to treat the adult patients so that they do 
        not leave the hospital. Hyaluronic acid injection can reconstruct the 
        philtrum ridge, and even labial tubercle. In this article, two cases are 
        presented to examine the efficacy of hyaluronic acid for the treatment 
        of scars. |
