Can’t smile upward? Rappoel Dermatology uses Coretox to relax the depressor anguli oris \u2014 5-minute treatment for a naturally upward smile<\/div>\n<\/p><\/div>\n<p>Drooping mouth corners are one of the main reasons people look ‘bitter,’ ‘unhappy,’ or ‘old.’ The position of the mouth corners is determined by the balance of two muscle groups \u2014 the levator anguli oris (lifting the corner up) and the depressor anguli oris (pulling it down). When the depressor anguli oris (DAO) is overactive, the corners are constantly pulled downward, making the face look displeased, bitter, or tired even at rest. Causes: (1) Aging \u2014 long-term DAO contraction with reduced skin elasticity gradually droops the corners. (2) Expression habits \u2014 habitual lip pursing, teeth clenching, or melancholic expressions overuse the DAO. (3) Facial structure \u2014 those with mandibular retrusion or a short chin are more prone to mouth corner drooping. (4) Bone resorption \u2014 the anterolateral mandible absorbs with age, the DAO attachment point descends, and the corners follow. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox \u2014 precise DAO relaxation, 5-minute treatment, with corners naturally lifting in 3-5 days for a warm, approachable smile.<\/p>\n<h2>Technical Advantages of Coretox Mouth Corner Lift<\/h2>\n<ul>\n<li><strong>Precise DAO relaxation:<\/strong> After injection into the DAO, Coretox blocks neuromuscular signaling, relaxing the overactive depressor \u2014 the corners are no longer pulled down, the levator’s upward force naturally dominates, and the corners lift<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with complex proteins removed, reducing antibody and resistance risk. The mouth is a delicate expression area \u2014 high-purity formulation spreads less, reducing risk of spreading to the depressor labii inferioris and mentalis causing lower lip stiffness<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 DAO begins relaxing at 3-5 days, corners naturally lift, optimal at two weeks<\/li>\n<li><strong>Natural lift without stiffness:<\/strong> Coretox only relaxes the DAO’s downward pull, without affecting the levator’s upward force \u2014 smiling remains natural, corners lift upward without stiffness<\/li>\n<li><strong>Minimally invasive with no recovery:<\/strong> Only 2-4 injection points, completed in 5 minutes \u2014 pinholes close in 1 day, no surgery or recovery, doable on a lunch break<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Mouth Corner Issues<\/h2>\n<ul>\n<li><strong>Pure drooping corners type:<\/strong> Clearly drooping corners at rest, bitter look. Strategy: Coretox 4-8 units per side in 1-2 points at the DAO \u2014 corners naturally lift 2-3mm after relaxation, bitter look improves<\/li>\n<li><strong>Drooping corners + marionette lines type:<\/strong> Drooping with marionette lines (grooves from corner to chin). Strategy: Coretox DAO relaxation (4-8 units per side) + HA marionette line filler (0.3-0.5ml per side) \u2014 Botox lifts corners, filler smooths grooves, dual improvement<\/li>\n<li><strong>Drooping corners + nasolabial fold type:<\/strong> Drooping with deepening nasolabial folds. Strategy: Coretox DAO (4-8 units per side) + HA nasolabial fold filler (0.5-1.0ml per side) \u2014 lift corners + smooth folds, overall mid-lower face rejuvenation<\/li>\n<li><strong>Drooping corners + chin retrusion type:<\/strong> Short, retruded chin causing corner drooping. Strategy: Coretox DAO (4-8 units per side) + HA chin filler (1-2ml) \u2014 Botox lifts corners, filler elongates the chin, overall lower-third proportion improves<\/li>\n<li><strong>Asymmetric type (unilateral drooping):<\/strong> One corner clearly lower than the other. Strategy: Inject Coretox only on the lower side (4-6 units) \u2014 symmetry restored after relaxation<\/li>\n<\/ul>\n<h2>Rappoel Mouth Corner Coretox Treatment Protocol<\/h2>\n<ol>\n<li><strong>Corner assessment and plan design (5 min):<\/strong> Patient relaxes face, smiles, and purses lips to assess corner position and DAO activity \u2192 check marionette and nasolabial lines \u2192 photograph \u2192 establish injection plan (dosage, points)<\/li>\n<li><strong>Disinfection preparation (2 min):<\/strong> Corner area cleansing \u2192 alcohol swab disinfection \u2192 mark 1-2 injection points per side (mid-DAO, avoiding the depressor labii inferioris and facial artery)<\/li>\n<li><strong>Precise injection (3 min):<\/strong> 32G ultra-fine needle \u2192 3-5 units Coretox per point \u2192 intramuscular depth \u2192 4-8 units total per side \u2192 gentle pressure after injection<\/li>\n<li><strong>Immediate assessment and guidance (3 min):<\/strong> Patient smiles to confirm corner improvement \u2192 post-care instructions (avoid lying flat and massaging for 4 hours, avoid strenuous exercise for 24 hours, avoid high-heat for 1 week, avoid testing by forceful pursing) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The mouth corner Coretox injection takes about 10 minutes, with onset at 2-3 days, visibly lifted corners at 5-7 days, lasting 3-5 months.

Can’t smile upward? Rappoel Dermatology uses Coretox to relax the depressor anguli oris \u2014 5-minute treatment for a naturally upward smile<\/div>\n<\/p><\/div>\n<p>Drooping mouth corners are one of the main reasons people look ‘bitter,’ ‘unhappy,’ or ‘old.’ The position of the mouth corners is determined by the balance of two muscle groups \u2014 the levator anguli oris (lifting the corner up) and the depressor anguli oris (pulling it down). When the depressor anguli oris (DAO) is overactive, the corners are constantly pulled downward, making the face look displeased, bitter, or tired even at rest. Causes: (1) Aging \u2014 long-term DAO contraction with reduced skin elasticity gradually droops the corners. (2) Expression habits \u2014 habitual lip pursing, teeth clenching, or melancholic expressions overuse the DAO. (3) Facial structure \u2014 those with mandibular retrusion or a short chin are more prone to mouth corner drooping. (4) Bone resorption \u2014 the anterolateral mandible absorbs with age, the DAO attachment point descends, and the corners follow. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox \u2014 precise DAO relaxation, 5-minute treatment, with corners naturally lifting in 3-5 days for a warm, approachable smile.<\/p>\n<h2>Technical Advantages of Coretox Mouth Corner Lift<\/h2>\n<ul>\n<li><strong>Precise DAO relaxation:<\/strong> After injection into the DAO, Coretox blocks neuromuscular signaling, relaxing the overactive depressor \u2014 the corners are no longer pulled down, the levator’s upward force naturally dominates, and the corners lift<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with complex proteins removed, reducing antibody and resistance risk. The mouth is a delicate expression area \u2014 high-purity formulation spreads less, reducing risk of spreading to the depressor labii inferioris and mentalis causing lower lip stiffness<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 DAO begins relaxing at 3-5 days, corners naturally lift, optimal at two weeks<\/li>\n<li><strong>Natural lift without stiffness:<\/strong> Coretox only relaxes the DAO’s downward pull, without affecting the levator’s upward force \u2014 smiling remains natural, corners lift upward without stiffness<\/li>\n<li><strong>Minimally invasive with no recovery:<\/strong> Only 2-4 injection points, completed in 5 minutes \u2014 pinholes close in 1 day, no surgery or recovery, doable on a lunch break<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Mouth Corner Issues<\/h2>\n<ul>\n<li><strong>Pure drooping corners type:<\/strong> Clearly drooping corners at rest, bitter look. Strategy: Coretox 4-8 units per side in 1-2 points at the DAO \u2014 corners naturally lift 2-3mm after relaxation, bitter look improves<\/li>\n<li><strong>Drooping corners + marionette lines type:<\/strong> Drooping with marionette lines (grooves from corner to chin). Strategy: Coretox DAO relaxation (4-8 units per side) + HA marionette line filler (0.3-0.5ml per side) \u2014 Botox lifts corners, filler smooths grooves, dual improvement<\/li>\n<li><strong>Drooping corners + nasolabial fold type:<\/strong> Drooping with deepening nasolabial folds. Strategy: Coretox DAO (4-8 units per side) + HA nasolabial fold filler (0.5-1.0ml per side) \u2014 lift corners + smooth folds, overall mid-lower face rejuvenation<\/li>\n<li><strong>Drooping corners + chin retrusion type:<\/strong> Short, retruded chin causing corner drooping. Strategy: Coretox DAO (4-8 units per side) + HA chin filler (1-2ml) \u2014 Botox lifts corners, filler elongates the chin, overall lower-third proportion improves<\/li>\n<li><strong>Asymmetric type (unilateral drooping):<\/strong> One corner clearly lower than the other. Strategy: Inject Coretox only on the lower side (4-6 units) \u2014 symmetry restored after relaxation<\/li>\n<\/ul>\n<h2>Rappoel Mouth Corner Coretox Treatment Protocol<\/h2>\n<ol>\n<li><strong>Corner assessment and plan design (5 min):<\/strong> Patient relaxes face, smiles, and purses lips to assess corner position and DAO activity \u2192 check marionette and nasolabial lines \u2192 photograph \u2192 establish injection plan (dosage, points)<\/li>\n<li><strong>Disinfection preparation (2 min):<\/strong> Corner area cleansing \u2192 alcohol swab disinfection \u2192 mark 1-2 injection points per side (mid-DAO, avoiding the depressor labii inferioris and facial artery)<\/li>\n<li><strong>Precise injection (3 min):<\/strong> 32G ultra-fine needle \u2192 3-5 units Coretox per point \u2192 intramuscular depth \u2192 4-8 units total per side \u2192 gentle pressure after injection<\/li>\n<li><strong>Immediate assessment and guidance (3 min):<\/strong> Patient smiles to confirm corner improvement \u2192 post-care instructions (avoid lying flat and massaging for 4 hours, avoid strenuous exercise for 24 hours, avoid high-heat for 1 week, avoid testing by forceful pursing) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The mouth corner Coretox injection takes about 10 minutes, with onset at 2-3 days, visibly lifted corners at 5-7 days, lasting 3-5 months.
