Swallowing remains completely normal after treatment.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How soon do results show, and how long do they last?<\/div>\n<div class=\"faq-a\">Visible improvement at 7\u201314 days. Duration: 3\u20135 months. Maintenance every 4\u20136 months keeps the neck smooth.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can Coretox treat static neck lines too?<\/div>\n<div class=\"faq-a\">Coretox primarily addresses dynamic lines (those caused by muscle pull). For static lines present at rest, combining with Rejuran neck PDRN or HA skin booster provides collagen regeneration for deeper wrinkle improvement.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can I fly home immediately?<\/div>\n<div class=\"faq-a\">Yes \u2014 neck Coretox is a routine procedure with no special recovery. Normal activities resume same day.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is neck Coretox painful?<\/div>\n<div class=\"faq-a\">Using ultra-fine needles (31G\/32G) for superficial micro-dosing, most patients report minimal discomfort and no special anesthesia is needed.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Book Coretox Neck Line Treatment at Rappoel Seoul<\/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>Relax the platysma to erase horizontal neck lines \u2014 smooth, youthful neck without surgery in just one session<\/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-1253","post","type-post","status-publish","format-standard","hentry","category-botox-en"],"_links":{"self":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1253","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=1253"}],"version-history":[{"count":1,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1253\/revisions"}],"predecessor-version":[{"id":1255,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1253\/revisions\/1255"}],"wp:attachment":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/media?parent=1253"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/categories?post=1253"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/tags?post=1253"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
