(This Determines If Botulinum Toxin Will Work)<\/h2>\n<p>Calf botulinum toxin is effective <strong>only for muscle-type calf enlargement<\/strong>:<\/p>\n<ul>\n<li><strong>Muscle-type calves:<\/strong> Overdeveloped gastrocnemius muscle \u2014 caused by genetics, running, hiking, or habitual high-heel wear. Botulinum toxin can reduce calf circumference by <strong>1\u20133 cm<\/strong><\/li>\n<li><strong>Fat-type calves:<\/strong> Subcutaneous fat accumulation \u2014 botulinum toxin has no effect; ONDA or lipolysis treatments are more appropriate<\/li>\n<li><strong>Edema-type calves:<\/strong> Poor circulation \u2014 primarily addressed through lifestyle changes and lymphatic drainage<\/li>\n<\/ul>\n<p>Rappoel doctors perform a standing and toe-raise assessment during consultation to precisely evaluate gastrocnemius prominence and confirm suitability.<\/p>\n<h2>How Coretox Slims the Calf<\/h2>\n<p>When <strong>Coretox<\/strong> is injected into the gastrocnemius, it blocks nerve transmission signals. Without stimulation, the muscle gradually atrophies over 3\u20136 weeks, naturally reducing calf volume.<\/p>\n<ul>\n<li><strong>Visible results:<\/strong> Begin at 3\u20134 weeks; most pronounced at 6\u20138 weeks<\/li>\n<li><strong>Duration:<\/strong> Approximately <strong>5\u20137 months<\/strong> (longer than facial muscle injections)<\/li>\n<li><strong>Average reduction:<\/strong> Typically <strong>1\u20133 cm<\/strong> maximum calf circumference depending on muscle mass<\/li>\n<\/ul>\n<p>With repeated treatments, atrophy effects may become more lasting \u2014 some patients see significantly extended results after 3\u20134 sessions.<\/p>\n<h2>The Treatment Session<\/h2>\n<ol>\n<li><strong>Standing assessment (10 min):<\/strong> Doctor evaluates gastrocnemius contour and marks injection zones<\/li>\n<li><strong>Prep (10 min):<\/strong> Cleanse and optional topical numbing cream<\/li>\n<li><strong>Injection (20\u201330 min):<\/strong> Multi-point injection into gastrocnemius, typically 10\u201315 points per leg<\/li>\n<li><strong>Aftercare:<\/strong> Avoid pressing for 4 hours; no strenuous exercise same day<\/li>\n<\/ol>\n<p>The full treatment is comfortable and patients walk out normally \u2014 no impact on sightseeing or daily activities.<\/p>\n<h2>Important Considerations<\/h2>\n<ul>\n<li><strong>Not immediate:<\/strong> Allow 3\u20136 weeks for results; plan treatment before key events or travel<\/li>\n<li><strong>Temporary weakness:<\/strong> Mild reduction in calf strength (especially uphill) for the first 2\u20134 weeks while adapting<\/li>\n<li><strong>Maintenance required:<\/strong> Muscle gradually recovers if injections stop; regular touch-ups needed to maintain results<\/li>\n<\/ul>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will calf Coretox affect my ability to walk normally?<\/div>\n<div class=\"faq-a\">A mild feeling of leg weakness, particularly on stairs or inclines, is common for the first 2\u20134 weeks. Most patients adapt completely and daily walking is unaffected.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many units are needed for calf slimming?<\/div>\n<div class=\"faq-a\">Typically 60\u2013100 units per gastrocnemius, depending on muscle size. First-time patients usually start conservatively to assess response.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can I exercise after calf botulinum toxin?<\/div>\n<div class=\"faq-a\">Avoid intense calf-focused exercise (running, jumping rope) on the day of treatment. Light activity is fine after 24 hours; normal exercise can resume after 2 weeks.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will my calves get bigger when the effect wears off?<\/div>\n<div class=\"faq-a\">No. When the botulinum toxin effect fades, muscle returns to its original size \u2014 it doesn’t overshoot and become larger. Regular maintenance keeps the muscle consistently reduced.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How do I know if my calves are muscle-type or fat-type?<\/div>\n<div class=\"faq-a\">Simple self-test: stand and rise on your toes. If you see a prominent hard bulge appear, muscle is the main component. If there’s minimal change, fat or edema is more likely. Rappoel doctors will confirm the type during your consultation.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How many times per year do I need treatment to maintain results?<\/div>\n<div class=\"faq-a\">Most patients maintain results with 2 sessions per year. With regular treatment, atrophy effects may gradually lengthen, potentially reducing to once-yearly maintenance.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Contact Rappoel Dermatology Clinic<\/h3>\n<p>\ud83d\udccd 77, Seocho-daero, Seocho-gu, Seoul, South Korea<\/p>\n<p>\ud83d\udd50 Mon\u2013Fri 10:00\u201319:00 \u00b7 Sat 10:00\u201317:00<\/p>\n<p>\ud83d\udcac WeChat Main: rappoelkr | WeChat Backup: rappoelkr2 | LINE: rappoelkr<\/p>\n<p style=\"margin-top:16px;font-size:13px;color:#8B7355;\">Scan to connect with us<\/p>\n<div style=\"display:flex;justify-content:center;gap:16px;flex-wrap:wrap;margin-top:10px;\">\n<div style=\"text-align:center;\">\n <img decoding=\"async\" src=\"https:\/\/rappoel-clinic.com\/wp-content\/uploads\/2026\/04\/Rappoel\u5fae\u4fe1\u4e8c\u7ef4\u7801\uff08\u4e3b\u53f7\uff09-1.png\" alt=\"WeChat Main QR Code\" style=\"width:120px;height:120px;border-radius:6px;\" \/><\/p>\n<p style=\"font-size:11px;color:#6b5240;margin-top:4px;\">WeChat (Main)<\/p>\n<\/p><\/div>\n<div style=\"text-align:center;\">\n <img decoding=\"async\" src=\"https:\/\/rappoel-clinic.com\/wp-content\/uploads\/2026\/04\/Rappoel\u5fae\u4fe1\u4e8c\u7ef4\u7801\uff08\u5907\u7528\u53f7\uff09-1.png\" alt=\"WeChat Backup QR Code\" style=\"width:120px;height:120px;border-radius:6px;\" \/><\/p>\n<p style=\"font-size:11px;color:#6b5240;margin-top:4px;\">WeChat (Backup)<\/p>\n<\/p><\/div>\n<div style=\"text-align:center;\">\n <img decoding=\"async\" src=\"https:\/\/rappoel-clinic.com\/wp-content\/uploads\/2026\/04\/Line\u4e8c\u7ef4\u7801-1.jpg\" alt=\"LINE QR Code\" style=\"width:120px;height:120px;border-radius:6px;\" \/><\/p>\n<p style=\"font-size:11px;color:#6b5240;margin-top:4px;\">LINE<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n<\/div>\n<p><\/body><br \/>\n<\/html><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Coretox injections gradually reduce gastrocnemius muscle volume \u2014 slimmer calf contour visible in 3\u20136 weeks, lasting 5\u20137 months<\/p>","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[66],"tags":[],"class_list":["post-1080","post","type-post","status-publish","format-standard","hentry","category-botox-en"],"_links":{"self":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1080","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/comments?post=1080"}],"version-history":[{"count":1,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1080\/revisions"}],"predecessor-version":[{"id":1082,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1080\/revisions\/1082"}],"wp:attachment":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/media?parent=1080"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/categories?post=1080"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/tags?post=1080"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
