The problem may be overactive Depressor Anguli Oris muscle. Seoul&#8217;s Rappoel uses Coretox to precisely relax DAO for naturally upturned mouth corners<\/div>\n<\/p><\/div>\n<p>Downturned mouth corners are a common concern \u2014 you feel fine, but people keep asking &#8220;Are you upset?&#8221; This is often caused by overactive Depressor Anguli Oris (DAO) muscle that constantly pulls the mouth corners downward. With age, DAO strength increases while lifting muscles weaken, making the downturn more pronounced. Seoul&#8217;s Rappoel Dermatology uses Korean Coretox to precisely relax the DAO muscle, restoring a natural upward angle to the mouth corners.<\/p>\n<h2>Why Do Mouth Corners Droop?<\/h2>\n<ul>\n<li><strong>Overactive DAO Muscle:<\/strong> Naturally strong DAO or overuse from facial habits constantly pulls corners down<\/li>\n<li><strong>Aging:<\/strong> Fat loss and weakening of lifting muscles allow downward pull to dominate<\/li>\n<li><strong>Skeletal Structure:<\/strong> Receded jaw or naturally downward-angled mouth corners are more prone<\/li>\n<li><strong>Dental Occlusion:<\/strong> Certain bite issues can affect mouth corner position<\/li>\n<li><strong>Expression Habits:<\/strong> Chronic lip-pressing or jaw-clenching strengthens DAO<\/li>\n<\/ul>\n<h2>Coretox DAO Relaxation Treatment Process<\/h2>\n<ol>\n<li><strong>Pre-treatment Assessment:<\/strong> Doctor observes mouth corner position at rest and during expression, confirming DAO influence<\/li>\n<li><strong>Marking Injection Points:<\/strong> Points marked about 1cm lateral to mouth corners, above mandibular border, avoiding orbicularis oris<\/li>\n<li><strong>Precise Injection:<\/strong> Approximately 2-5 units of Coretox per side using ultra-fine needle, minimal pain<\/li>\n<li><strong>Post-injection Observation:<\/strong> 15-minute observation for any adverse reactions<\/li>\n<li><strong>Total Time:<\/strong> About 10-15 minutes<\/li>\n<li><strong>Onset:<\/strong> Results appear in 3-7 days, peak at 2 weeks<\/li>\n<li><strong>Duration:<\/strong> Typically 3-4 months<\/li>\n<\/ol>\n<h2>Ideal Candidates<\/h2>\n<ul>\n<li>Noticeably downturned mouth at rest, looking unhappy or tired<\/li>\n<li>Mouth corners still angle downward when smiling<\/li>\n<li>Frequently asked &#8220;Are you in a bad mood?&#8221;<\/li>\n<li>Not suitable for or not wanting surgical lifting<\/li>\n<li>Wanting quick, no-downtime improvement of mouth corner position<\/li>\n<\/ul>\n<p>Coretox is a purified botulinum toxin produced by Korean company Hugel, with very low impurity protein content, ideal for precise facial injections.
