Coretox relaxes the dilator naris muscle to keep your nose refined and compact in every expression<\/div>\n<\/p><\/div>\n<p>Many people notice their nostrils flare significantly when smiling, making the nose appear wider in photos. This happens because the dilator part of the nasalis muscle contracts during expressions, pulling the nostrils outward. Seoul’s Rappoel Dermatology uses Coretox to precisely relax the dilator naris muscle, keeping your nostrils stable when smiling so your nose looks more refined and compact.<\/p>\n<h2>Causes of Nasal Flaring<\/h2>\n<ul>\n<li><strong>Overactive Nasalis Muscle:<\/strong> The dilator portion of the nasalis contracts during smiling and deep breathing, pulling nostrils outward<\/li>\n<li><strong>Natural Nose Shape:<\/strong> Round nasal tips and wide nostrils show more flaring when smiling<\/li>\n<li><strong>Expression Habits:<\/strong> Some people habitually inhale forcefully when laughing, accentuating nasal flare<\/li>\n<li><strong>Post-Rhinoplasty:<\/strong> After certain nose surgeries, compensatory nasalis strengthening may increase flaring<\/li>\n<li><strong>Aging:<\/strong> Nasal cartilage loosens with age, potentially worsening flare over time<\/li>\n<\/ul>\n<h2>Coretox Nasal Flare Treatment Process<\/h2>\n<ol>\n<li><strong>Pre-treatment Assessment:<\/strong> Doctor observes flare degree and direction as patient smiles and takes deep breaths<\/li>\n<li><strong>Marking Injection Points:<\/strong> Bilateral points marked at the alar groove, precisely targeting the dilator naris<\/li>\n<li><strong>Micro-dose Injection:<\/strong> Approximately 1-3 units of Coretox per side using ultra-fine needle, virtually painless<\/li>\n<li><strong>Post-injection Observation:<\/strong> 10-minute observation for any adverse reactions<\/li>\n<li><strong>Total Time:<\/strong> About 5-10 minutes<\/li>\n<li><strong>Onset:<\/strong> Results appear in 3-7 days, peak at 2 weeks<\/li>\n<li><strong>Duration:<\/strong> Typically 3-4 months<\/li>\n<\/ol>\n<h2>Nasal Flare Treatment vs Alar Base Surgery<\/h2>\n<ul>\n<li><strong>Coretox Treatment:<\/strong> Non-surgical, no downtime, reversible, suitable for mild to moderate flare, maintained every 3-4 months<\/li>\n<li><strong>Alar Base Surgery:<\/strong> Permanent results, requires surgical incision recovery, suitable for severe flare or thick alar tissue<\/li>\n<li><strong>Combined Approach:<\/strong> Try Coretox first to see results; if satisfied, maintain long-term; if flare remains significant, consider surgery<\/li>\n<li><strong>Filler Adjunct:<\/strong> Small amount of filler at the nasal tip can visually reduce the appearance of nasal flare<\/li>\n<\/ul>\n<p>Coretox treatment for nasal flare is one of the most delicate procedures in facial micro-aesthetics. Injection amounts are tiny (1-3 units per side), but placement precision is critical. Injecting too laterally may affect facial expression muscles; too medially may impair nostril dilation function. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, with doctors experienced in facial muscle anatomy who precisely control injection placement and dosage.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will Coretox for nasal flare affect breathing?<\/div>\n<div class=\"faq-a\">At normal doses, no.

Coretox relaxes the dilator naris muscle to keep your nose refined and compact in every expression<\/div>\n<\/p><\/div>\n<p>Many people notice their nostrils flare significantly when smiling, making the nose appear wider in photos. This happens because the dilator part of the nasalis muscle contracts during expressions, pulling the nostrils outward. Seoul’s Rappoel Dermatology uses Coretox to precisely relax the dilator naris muscle, keeping your nostrils stable when smiling so your nose looks more refined and compact.<\/p>\n<h2>Causes of Nasal Flaring<\/h2>\n<ul>\n<li><strong>Overactive Nasalis Muscle:<\/strong> The dilator portion of the nasalis contracts during smiling and deep breathing, pulling nostrils outward<\/li>\n<li><strong>Natural Nose Shape:<\/strong> Round nasal tips and wide nostrils show more flaring when smiling<\/li>\n<li><strong>Expression Habits:<\/strong> Some people habitually inhale forcefully when laughing, accentuating nasal flare<\/li>\n<li><strong>Post-Rhinoplasty:<\/strong> After certain nose surgeries, compensatory nasalis strengthening may increase flaring<\/li>\n<li><strong>Aging:<\/strong> Nasal cartilage loosens with age, potentially worsening flare over time<\/li>\n<\/ul>\n<h2>Coretox Nasal Flare Treatment Process<\/h2>\n<ol>\n<li><strong>Pre-treatment Assessment:<\/strong> Doctor observes flare degree and direction as patient smiles and takes deep breaths<\/li>\n<li><strong>Marking Injection Points:<\/strong> Bilateral points marked at the alar groove, precisely targeting the dilator naris<\/li>\n<li><strong>Micro-dose Injection:<\/strong> Approximately 1-3 units of Coretox per side using ultra-fine needle, virtually painless<\/li>\n<li><strong>Post-injection Observation:<\/strong> 10-minute observation for any adverse reactions<\/li>\n<li><strong>Total Time:<\/strong> About 5-10 minutes<\/li>\n<li><strong>Onset:<\/strong> Results appear in 3-7 days, peak at 2 weeks<\/li>\n<li><strong>Duration:<\/strong> Typically 3-4 months<\/li>\n<\/ol>\n<h2>Nasal Flare Treatment vs Alar Base Surgery<\/h2>\n<ul>\n<li><strong>Coretox Treatment:<\/strong> Non-surgical, no downtime, reversible, suitable for mild to moderate flare, maintained every 3-4 months<\/li>\n<li><strong>Alar Base Surgery:<\/strong> Permanent results, requires surgical incision recovery, suitable for severe flare or thick alar tissue<\/li>\n<li><strong>Combined Approach:<\/strong> Try Coretox first to see results; if satisfied, maintain long-term; if flare remains significant, consider surgery<\/li>\n<li><strong>Filler Adjunct:<\/strong> Small amount of filler at the nasal tip can visually reduce the appearance of nasal flare<\/li>\n<\/ul>\n<p>Coretox treatment for nasal flare is one of the most delicate procedures in facial micro-aesthetics. Injection amounts are tiny (1-3 units per side), but placement precision is critical. Injecting too laterally may affect facial expression muscles; too medially may impair nostril dilation function. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, with doctors experienced in facial muscle anatomy who precisely control injection placement and dosage.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Will Coretox for nasal flare affect breathing?<\/div>\n<div class=\"faq-a\">At normal doses, no. Nasal flaring is primarily controlled by the dilator naris muscle, while everyday breathing relies on the diaphragm and intercostal muscles. Coretox only relaxes the small muscles on either side of the nostrils, not affecting normal breathing. However, excessive dosage may reduce nostril expansion during forceful deep breathing, so the doctor strictly limits the dose to 1-3 units per side.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How soon does Coretox for nasal flare work?<\/div>\n<div class=\"faq-a\">Typically 3-7 days to see initial results, with peak effect at 2 weeks. You will notice significantly reduced nostril flaring when smiling, making your nose look more refined in photos. We recommend completing the injection 2 weeks before important events.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Can Coretox nasal treatment be combined with nose filler?<\/div>\n<div class=\"faq-a\">Yes, and they complement each other well. Coretox controls nostril flaring during smiling, while filler adds height and definition to the nasal bridge and tip. Together, they optimize the nose appearance in both static and dynamic states. Typically, Coretox is injected first, followed by filler 2 weeks later after the toxin has taken full effect.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">Is Coretox nasal flare treatment painful?<\/div>\n<div class=\"faq-a\">Although the nasal area is sensitive, the injection amount is minimal (1-3 units per side) using the finest needle, so pain is very low. No numbing cream needed. The entire process takes 5-10 minutes. Mild soreness may occur but usually disappears within hours.<\/div>\n<\/div>\n<div class=\"faq-item\">\n<div class=\"faq-q\">How much does nasal flare treatment cost in Korea?<\/div>\n<div class=\"faq-a\">Costs vary by individual and clinic. Rappoel Clinic offers reasonable pricing \u2014 contact via WeChat (rappoelkr) or Line for consultation. Nasal flare Coretox uses very little product (2-6 units total), making it much less expensive than full-face Botox, offering excellent value as a micro-refinement procedure.<\/div>\n<\/div>\n<div class=\"cta\">\n<h3>Want a More Refined Nose When Smiling?
