Seoul Rappoel’s Coretox Micro-Injection Treatment for Hyperhidrosis<\/h1>\n<div class=\"sub\">10-minute treatment \u2014 6 months of dryness \u2014 a non-surgical solution to finally overcome embarrassing excessive sweating<\/div>\n<\/p><\/div>\n<p>Hyperhidrosis is a common condition of sweat gland overactivity, causing persistent and excessive sweating in the underarms, palms, or soles \u2014 even without exercise or heat. This is not simply sweating easily \u2014 it soaks through clothing, causes social embarrassment, and impacts professional image and quality of life. Seoul Rappoel Clinic offers Coretox botulinum toxin micro-injection therapy for hyperhidrosis, blocking the nerve signals to sweat glands at the source. A single treatment provides approximately 6 months of dry comfort.<\/p>\n<h2>Diagnostic Criteria for Hyperhidrosis<\/h2>\n<p>You may have primary hyperhidrosis if you meet at least two of the following:<\/p>\n<ul>\n<li>Sweating is disproportionate to ambient temperature and physical activity, occurring without obvious triggers<\/li>\n<li>Sweating is bilateral and symmetrical (e.g., both underarms soak clothing simultaneously)<\/li>\n<li>Troublesome excessive sweating occurs at least 1\u20132 times per week<\/li>\n<li>Onset is typically before age 25<\/li>\n<li>Sweating does not occur during sleep (nocturnal sweating may suggest other underlying medical conditions)<\/li>\n<li>A clear genetic tendency (family members often also have hyperhidrosis)<\/li>\n<\/ul>\n<h2>How Coretox Stops Excessive Sweating<\/h2>\n<ul>\n<li><strong>Blocks sweat gland nerve signals:<\/strong> Coretox selectively inhibits acetylcholine release from sympathetic nerve terminals supplying eccrine sweat glands<\/li>\n<li><strong>Reduced sweat gland activity:<\/strong> Without nerve signaling, sweat glands drastically reduce secretion<\/li>\n<li><strong>Localized effect only:<\/strong> The effect is confined to the injected area \u2014 the rest of the body continues to sweat normally for thermoregulation<\/li>\n<li><strong>No gland damage:<\/strong> The effect is functional (inhibition, not destruction); sweat gland function recovers after the treatment wears off<\/li>\n<\/ul>\n<h2>Rappoel’s Hyperhidrosis Protocol<\/h2>\n<ul>\n<li><strong>Pre-treatment iodine-starch test:<\/strong> Iodine and starch applied to the underarm to map the active sweating areas and severity<\/li>\n<li><strong>Grid-marked injection:<\/strong> Injection grid marked based on iodine-starch results to ensure complete coverage<\/li>\n<li><strong>Ultra-fine intradermal injection:<\/strong> Coretox delivered into the dermis with 32G ultra-fine needles<\/li>\n<li><strong>Bilateral symmetrical treatment:<\/strong> Equal dosing for both underarms; typically approximately 100 units total<\/li>\n<li><strong>10-minute procedure:<\/strong> The entire injection process takes about 10 minutes<\/li>\n<\/ul>\n<h2>Treatment Timeline<\/h2>\n<ul>\n<li><strong>3\u20135 days:<\/strong> Noticeable reduction in sweating begins<\/li>\n<li><strong>1\u20132 weeks:<\/strong> Maximum dryness achieved<\/li>\n<li><strong>Duration:<\/strong> Approximately 6\u20138 months before gradual return<\/li>\n<li><strong>Maintenance:<\/strong> 1\u20132 treatments per year maintain dryness<\/li>\n<\/ul>\n<p>Suitable treatment areas: underarms (most common), palms, soles, frontal hairline.

A single treatment provides approximately 6 months of dry comfort.<\/p>\n<h2>Diagnostic Criteria for Hyperhidrosis<\/h2>\n<p>You may have primary hyperhidrosis if you meet at least two of the following:<\/p>\n<ul>\n<li>Sweating is disproportionate to ambient temperature and physical activity, occurring without obvious triggers<\/li>\n<li>Sweating is bilateral and symmetrical (e.g., both underarms soak clothing simultaneously)<\/li>\n<li>Troublesome excessive sweating occurs at least 1\u20132 times per week<\/li>\n<li>Onset is typically before age 25<\/li>\n<li>Sweating does not occur during sleep (nocturnal sweating may suggest other underlying medical conditions)<\/li>\n<li>A clear genetic tendency (family members often also have hyperhidrosis)<\/li>\n<\/ul>\n<h2>How Coretox Stops Excessive Sweating<\/h2>\n<ul>\n<li><strong>Blocks sweat gland nerve signals:<\/strong> Coretox selectively inhibits acetylcholine release from sympathetic nerve terminals supplying eccrine sweat glands<\/li>\n<li><strong>Reduced sweat gland activity:<\/strong> Without nerve signaling, sweat glands drastically reduce secretion<\/li>\n<li><strong>Localized effect only:<\/strong> The effect is confined to the injected area \u2014 the rest of the body continues to sweat normally for thermoregulation<\/li>\n<li><strong>No gland damage:<\/strong> The effect is functional (inhibition, not destruction); sweat gland function recovers after the treatment wears off<\/li>\n<\/ul>\n<h2>Rappoel’s Hyperhidrosis Protocol<\/h2>\n<ul>\n<li><strong>Pre-treatment iodine-starch test:<\/strong> Iodine and starch applied to the underarm to map the active sweating areas and severity<\/li>\n<li><strong>Grid-marked injection:<\/strong> Injection grid marked based on iodine-starch results to ensure complete coverage<\/li>\n<li><strong>Ultra-fine intradermal injection:<\/strong> Coretox delivered into the dermis with 32G ultra-fine needles<\/li>\n<li><strong>Bilateral symmetrical treatment:<\/strong> Equal dosing for both underarms; typically approximately 100 units total<\/li>\n<li><strong>10-minute procedure:<\/strong> The entire injection process takes about 10 minutes<\/li>\n<\/ul>\n<h2>Treatment Timeline<\/h2>\n<ul>\n<li><strong>3\u20135 days:<\/strong> Noticeable reduction in sweating begins<\/li>\n<li><strong>1\u20132 weeks:<\/strong> Maximum dryness achieved<\/li>\n<li><strong>Duration:<\/strong> Approximately 6\u20138 months before gradual return<\/li>\n<li><strong>Maintenance:<\/strong> 1\u20132 treatments per year maintain dryness<\/li>\n<\/ul>\n<p>Suitable treatment areas: underarms (most common), palms, soles, frontal hairline.

The rest of your body’s thermoregulatory sweating remains completely normal \u2014 exercise and hot-weather cooling are unaffected.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Are the injections painful?<\/div>\n<div class=\"faq-a\">With 32G ultra-fine needles and topical anesthetic, most patients tolerate it easily. The underarm area has moderate sensitivity, and most find it very manageable. The entire procedure takes about 10 minutes.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">When can I shower after treatment?<\/div>\n<div class=\"faq-a\">We recommend avoiding scrubbing the underarm area and hot showers for 24 hours. You can resume normal activities and fly the same day.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Does this affect body odor?<\/div>\n<div class=\"faq-a\">Hyperhidrosis treatment primarily targets eccrine glands \u2014 responsible for profuse watery sweat. The effect on apocrine glands \u2014 the main source of body odor \u2014 is limited. If body odor rather than sweat volume is your main concern, alternative treatments may need evaluation.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How often do I need repeat treatments?<\/div>\n<div class=\"faq-a\">Sweating gradually returns to pre-treatment levels in approximately 6\u20138 months. One to two treatments per year maintain dryness. Some individuals experience progressively longer-lasting effects with repeated treatments.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Book a Coretox Hyperhidrosis Treatment<\/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>10-minute treatment \u2014 6 months of dryness \u2014 a non-surgical solution to finally overcome embarrassing excessive sweating<\/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-1298","post","type-post","status-publish","format-standard","hentry","category-botox-en"],"_links":{"self":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1298","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=1298"}],"version-history":[{"count":1,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1298\/revisions"}],"predecessor-version":[{"id":1302,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/posts\/1298\/revisions\/1302"}],"wp:attachment":[{"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/media?parent=1298"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/categories?post=1298"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/rappoel-clinic.com\/en\/wp-json\/wp\/v2\/tags?post=1298"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
