Rappoel Dermatology uses Coretox to precisely inject the upper lip elevators \u2014 safely relaxing overactive muscles for a natural smile in 3 days<\/div>\n<\/p><\/div>\n<p>A gummy smile refers to excessive upper lip elevation during smiling or laughing, exposing more than 2mm of maxillary gingival tissue. While not a disease, a gummy smile can significantly affect facial aesthetics and social confidence \u2014 many people consciously suppress their smile, cover their mouth, or avoid social situations where they might laugh openly. The causes of gummy smile are multifactorial: (1) Hyperactive upper lip elevators \u2014 the levator labii superioris and levator labii superioris alaeque nasi contract excessively during smiling, over-elevating the upper lip. (2) Maxillary protrusion \u2014 excessive anterior maxillary development positions the gums forward, exposing them even with normal lip elevation. (3) Short upper lip \u2014 insufficient lip length (normal approximately 20-24mm), exposing more teeth at rest and more gum when smiling. (4) Gingival hypertrophy \u2014 excessive gum tissue growth covering too much tooth surface, making exposed gum appear more prominent. The most common and most suitable type for Botox treatment is the hyperactive elevator type \u2014 accounting for approximately 60-70% of gummy smiles. Rappoel Dermatology near Gangnam Station, Seoul, uses Korea’s Coretox botulinum toxin \u2014 precise injection into the upper lip elevators for safe and effective muscle relaxation, restoring a natural smile.<\/p>\n<h2>Technical Principles of Coretox Gummy Smile Treatment<\/h2>\n<ul>\n<li><strong>Botox relaxes upper lip elevators:<\/strong> Coretox is botulinum toxin type A \u2014 when injected into the levator labii superioris and levator labii superioris alaeque nasi, it blocks acetylcholine release at the neuromuscular junction, moderately relaxing the overactive elevators. With muscle relaxation, upper lip elevation amplitude decreases during smiling \u2014 clinical data shows 3-5mm average reduction in gum exposure at 1-2 weeks<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with unnecessary complex proteins removed, reducing antibody formation and resistance risk. Facial expression muscle treatment requires precise dose control \u2014 the high-purity formula’s smaller diffusion range enables precise relaxation control, avoiding over-relaxation causing lip droop<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 upper lip elevators begin relaxing at 3-5 days, optimal results at 1-2 weeks. Patients typically notice smile improvement within one week<\/li>\n<li><strong>Precise diffusion control:<\/strong> Gummy smile injection points are adjacent to the nasal ala and upper lip \u2014 excessive diffusion would affect the orbicularis oris, causing smile stiffness or mouth corner asymmetry. Coretox’s smaller diffusion range makes it safer for precise facial injection<\/li>\n<li><strong>Preservative-free hypoallergenic formulation:<\/strong> Coretox contains no animal-derived proteins or human serum albumin \u2014 reducing allergic reaction risk<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Gummy Smile Types<\/h2>\n<ul>\n<li><strong>Hyperactive elevator type (most common):<\/strong> Excessive upper lip elevation during smiling, gum exposure over 4mm, but normal lip position at rest. Strategy: inject Coretox into the levator labii superioris and levator labii superioris alaeque nasi \u2014 2 points per side, 2-3 units per point, bilateral total 8-12 units. This type responds best to Botox<\/li>\n<li><strong>Maxillary protrusion type:<\/strong> Excessive anterior maxillary development with forward gum position. Strategy: Botox can partially improve (relaxing elevators to reduce elevation), but the skeletal issue requires orthognathic surgery for definitive correction. Recommend trying Botox first to assess improvement \u2014 if satisfactory after gum reduction, continue maintenance; if not, consider surgery<\/li>\n<li><strong>Short upper lip type:<\/strong> Upper lip length under 20mm. Strategy: After Botox relaxes the elevators, lip elevation amplitude decreases, visually making the lip appear longer. Can combine with HA lip filler to increase lip volume and visual length \u2014 Botox + HA lip filler is an effective combination for short-lip gummy smile<\/li>\n<li><strong>Mixed type:<\/strong> Simultaneous hyperactive elevators + short lip + mild maxillary protrusion. Strategy: First inject Botox to improve muscle over-elevation (8-12 units), assess at 2 weeks. If significant gum show remains, combine with HA lip filler. Do not simultaneously do orthognathic surgery and Botox \u2014 assess non-surgical results first<\/li>\n<li><strong>Mild gummy type:<\/strong> Gum exposure 2-4mm, only prominent during full laughter. Strategy: Low-dose Coretox injection (bilateral total 6-8 units) suffices \u2014 no need for high doses, avoiding over-relaxation causing lip droop or smile stiffness<\/li>\n<\/ul>\n<h2>Rappoel Gummy Smile Botox Injection Treatment Protocol<\/h2>\n<ol>\n<li><strong>Gummy smile assessment and plan design (10 min):<\/strong> Patient smiles naturally and broadly \u2192 photograph and measure gum exposure and lip elevation amplitude \u2192 assess upper lip length \u2192 determine gummy smile type (muscular\/skeletal\/short-lip\/mixed) \u2192 establish injection plan (points, dosage)<\/li>\n<li><strong>Disinfection preparation (5 min):<\/strong> Facial cleansing \u2192 povidone-iodine preparation of nasal ala sides and upper lip area \u2192 mark injection points (1cm lateral to nasal ala and above nasal ala)<\/li>\n<li><strong>Precise injection (5-8 min):<\/strong> 32G ultra-fine needle \u2192 2 injection points per side (lateral to nasal ala and above nasal ala) \u2192 2-3 units Coretox per point \u2192 superficial injection (subcutaneous 2-3mm, into the superficial upper lip elevators) \u2192 gentle pressure after injection<\/li>\n<li><strong>Immediate assessment and guidance (5 min):<\/strong> Patient smiles to observe upper lip elevation \u2192 post-care instructions (avoid pressing injection area, avoid lying flat for 4 hours, avoid strenuous exercise for 24 hours, avoid facial massage for 1 week) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The entire gummy smile Coretox injection takes about 15-20 minutes, with onset at 3-5 days, optimal results at 1-2 weeks, lasting 3-4 months.

Rappoel Dermatology uses Coretox to precisely inject the upper lip elevators \u2014 safely relaxing overactive muscles for a natural smile in 3 days<\/div>\n<\/p><\/div>\n<p>A gummy smile refers to excessive upper lip elevation during smiling or laughing, exposing more than 2mm of maxillary gingival tissue. While not a disease, a gummy smile can significantly affect facial aesthetics and social confidence \u2014 many people consciously suppress their smile, cover their mouth, or avoid social situations where they might laugh openly. The causes of gummy smile are multifactorial: (1) Hyperactive upper lip elevators \u2014 the levator labii superioris and levator labii superioris alaeque nasi contract excessively during smiling, over-elevating the upper lip. (2) Maxillary protrusion \u2014 excessive anterior maxillary development positions the gums forward, exposing them even with normal lip elevation. (3) Short upper lip \u2014 insufficient lip length (normal approximately 20-24mm), exposing more teeth at rest and more gum when smiling. (4) Gingival hypertrophy \u2014 excessive gum tissue growth covering too much tooth surface, making exposed gum appear more prominent. The most common and most suitable type for Botox treatment is the hyperactive elevator type \u2014 accounting for approximately 60-70% of gummy smiles. Rappoel Dermatology near Gangnam Station, Seoul, uses Korea’s Coretox botulinum toxin \u2014 precise injection into the upper lip elevators for safe and effective muscle relaxation, restoring a natural smile.<\/p>\n<h2>Technical Principles of Coretox Gummy Smile Treatment<\/h2>\n<ul>\n<li><strong>Botox relaxes upper lip elevators:<\/strong> Coretox is botulinum toxin type A \u2014 when injected into the levator labii superioris and levator labii superioris alaeque nasi, it blocks acetylcholine release at the neuromuscular junction, moderately relaxing the overactive elevators. With muscle relaxation, upper lip elevation amplitude decreases during smiling \u2014 clinical data shows 3-5mm average reduction in gum exposure at 1-2 weeks<\/li>\n<li><strong>Coretox Korean-origin high-purity advantage:<\/strong> Coretox is 150kDa high-purity toxin with unnecessary complex proteins removed, reducing antibody formation and resistance risk. Facial expression muscle treatment requires precise dose control \u2014 the high-purity formula’s smaller diffusion range enables precise relaxation control, avoiding over-relaxation causing lip droop<\/li>\n<li><strong>Fast onset (2-3 days):<\/strong> Coretox clinical data shows average onset of 2-3 days \u2014 upper lip elevators begin relaxing at 3-5 days, optimal results at 1-2 weeks. Patients typically notice smile improvement within one week<\/li>\n<li><strong>Precise diffusion control:<\/strong> Gummy smile injection points are adjacent to the nasal ala and upper lip \u2014 excessive diffusion would affect the orbicularis oris, causing smile stiffness or mouth corner asymmetry. Coretox’s smaller diffusion range makes it safer for precise facial injection<\/li>\n<li><strong>Preservative-free hypoallergenic formulation:<\/strong> Coretox contains no animal-derived proteins or human serum albumin \u2014 reducing allergic reaction risk<\/li>\n<\/ul>\n<h2>Treatment Strategies for Different Gummy Smile Types<\/h2>\n<ul>\n<li><strong>Hyperactive elevator type (most common):<\/strong> Excessive upper lip elevation during smiling, gum exposure over 4mm, but normal lip position at rest. Strategy: inject Coretox into the levator labii superioris and levator labii superioris alaeque nasi \u2014 2 points per side, 2-3 units per point, bilateral total 8-12 units. This type responds best to Botox<\/li>\n<li><strong>Maxillary protrusion type:<\/strong> Excessive anterior maxillary development with forward gum position. Strategy: Botox can partially improve (relaxing elevators to reduce elevation), but the skeletal issue requires orthognathic surgery for definitive correction. Recommend trying Botox first to assess improvement \u2014 if satisfactory after gum reduction, continue maintenance; if not, consider surgery<\/li>\n<li><strong>Short upper lip type:<\/strong> Upper lip length under 20mm. Strategy: After Botox relaxes the elevators, lip elevation amplitude decreases, visually making the lip appear longer. Can combine with HA lip filler to increase lip volume and visual length \u2014 Botox + HA lip filler is an effective combination for short-lip gummy smile<\/li>\n<li><strong>Mixed type:<\/strong> Simultaneous hyperactive elevators + short lip + mild maxillary protrusion. Strategy: First inject Botox to improve muscle over-elevation (8-12 units), assess at 2 weeks. If significant gum show remains, combine with HA lip filler. Do not simultaneously do orthognathic surgery and Botox \u2014 assess non-surgical results first<\/li>\n<li><strong>Mild gummy type:<\/strong> Gum exposure 2-4mm, only prominent during full laughter. Strategy: Low-dose Coretox injection (bilateral total 6-8 units) suffices \u2014 no need for high doses, avoiding over-relaxation causing lip droop or smile stiffness<\/li>\n<\/ul>\n<h2>Rappoel Gummy Smile Botox Injection Treatment Protocol<\/h2>\n<ol>\n<li><strong>Gummy smile assessment and plan design (10 min):<\/strong> Patient smiles naturally and broadly \u2192 photograph and measure gum exposure and lip elevation amplitude \u2192 assess upper lip length \u2192 determine gummy smile type (muscular\/skeletal\/short-lip\/mixed) \u2192 establish injection plan (points, dosage)<\/li>\n<li><strong>Disinfection preparation (5 min):<\/strong> Facial cleansing \u2192 povidone-iodine preparation of nasal ala sides and upper lip area \u2192 mark injection points (1cm lateral to nasal ala and above nasal ala)<\/li>\n<li><strong>Precise injection (5-8 min):<\/strong> 32G ultra-fine needle \u2192 2 injection points per side (lateral to nasal ala and above nasal ala) \u2192 2-3 units Coretox per point \u2192 superficial injection (subcutaneous 2-3mm, into the superficial upper lip elevators) \u2192 gentle pressure after injection<\/li>\n<li><strong>Immediate assessment and guidance (5 min):<\/strong> Patient smiles to observe upper lip elevation \u2192 post-care instructions (avoid pressing injection area, avoid lying flat for 4 hours, avoid strenuous exercise for 24 hours, avoid facial massage for 1 week) \u2192 2-week follow-up<\/li>\n<\/ol>\n<p>The entire gummy smile Coretox injection takes about 15-20 minutes, with onset at 3-5 days, optimal results at 1-2 weeks, lasting 3-4 months.
