Nasal flare is an aesthetic concern for many — when smiling or laughing, the nostrils (sides of the nose) visibly expand outward, exposing the nostrils and making the nose look wider and larger, with the overall face appearing less refined. Nasal flare is controlled by the alar part of the nasalis muscle — this muscle group contracts during facial expression, pulling the nostrils outward. Those with pronounced nasal flare may have overactive nasalis muscles or naturally wider nostrils. For those who don’t want surgical nostril reduction, Coretox botulinum toxin offers a non-surgical option — relaxing the nasalis to reduce excessive nostril expansion during expression. Rappoel Dermatology near Gangnam Station, Seoul, uses Coretox for precise nasalis injection — 5-minute treatment, visible in 3-5 days, improving nasal flare during smiling.
Technical Advantages of Coretox Nasal Flare Reduction
- Precise nasalis alar relaxation: After injection into the nasalis alar part, Coretox blocks neuromuscular signaling, relaxing the overactive nasalis — the nostrils are no longer pulled outward, with 2-4mm reduction in flare during smiling, making the nose more refined
- Coretox Korean-origin high-purity advantage: Coretox is 150kDa high-purity toxin with complex proteins removed, reducing antibody and resistance risk. The nose is a delicate area — high-purity formulation spreads less, reducing risk of spreading to the levator labii superioris alaeque nasi causing upper lip stiffness
- Fast onset (2-3 days): Coretox clinical data shows average onset of 2-3 days — nasalis begins relaxing at 3-5 days, visibly reduced flare during smiling, optimal at two weeks
- Non-surgical with no recovery: Only 2 injection points, completed in 5 minutes — pinholes close in 1 day, no surgery or recovery, doable on a lunch break
- Combines with HA rhinoplasty: Coretox improves dynamic nasal flare (during smiling), HA rhinoplasty improves static nose shape — combining both addresses nose shape and nostrils non-surgically for comprehensive nasal enhancement
Treatment Strategies for Different Nasal Flare Issues
- Dynamic flare type (visible when smiling): Normal nostrils at rest but visibly expanding when smiling or laughing. Strategy: Coretox 3-5 units per side at the nasalis alar part — flare reduces 2-4mm after relaxation, best results
- Static wide nostril type (wide at rest): Nostrils already wide at rest, wider when smiling. Strategy: Coretox for dynamic flare (3-5 units per side) + if further narrowing needed, assess for HA nasal bridge filler (visually narrows nostrils) or surgical nostril reduction
- Flare + bulbous tip type: Nasal flare with a round, unrefined tip. Strategy: Coretox for dynamic nostril narrowing + HA nasal tip filler for sculpting — Botox narrows dynamic flare, filler refines tip contour
- Flare + low bridge type: Nasal flare with a low nasal bridge. Strategy: Coretox nasalis relaxation + HA nasal bridge filler — filler elevates the bridge, visually narrowing nostrils, plus Coretox for dynamic flare, dual effect
- Asymmetric nostril type: One nostril flares more or is wider than the other. Strategy: Inject Coretox only on the wider side (3-5 units) — symmetry restored after relaxation
Rappoel Nasal Flare Coretox Treatment Protocol
- Nasal flare assessment and plan design (5 min): Patient at rest, smiling, and laughing to assess flare degree → photograph dynamic changes → check nasalis position → establish injection plan (dosage, points)
- Disinfection preparation (2 min): Nasal cleansing → alcohol swab disinfection → mark 1 injection point per side (upper lateral nostril, mid-alar nasalis)
- Precise injection (3 min): 32G ultra-fine needle → 3-5 units Coretox per side → intramuscular depth (subcutaneous to nasalis layer) → gentle pressure after injection
- Immediate assessment and guidance (3 min): Patient smiles to confirm flare improvement → post-care instructions (avoid lying flat and massaging for 4 hours, avoid strenuous exercise for 24 hours, avoid high-heat for 1 week, avoid testing by forceful nose wrinkling) → 2-week follow-up
The nasal flare Coretox injection takes about 10 minutes, with onset at 2-3 days, visibly reduced flare at 5-7 days, lasting 3-4 months. Located 3 minutes from Gangnam Station Exit 10, with seamless English and Chinese consultation.
Frequently Asked Questions
How long does Coretox nasal flare reduction last? How often do I need injections?
Coretox nasal flare reduction typically lasts 3-4 months — the nasalis is frequently active (breathing, expression) with small doses (3-5 units per side), lasting slightly less than large muscles like the masseter. Rappoel recommends: injection every 3-4 months for maintenance. Benefits of regular treatment: (1) Continuous suppression of nasalis over-contraction prevents recurrent flare. (2) After prolonged relaxation, baseline muscle tone decreases, allowing some patients to extend to 4-5 month intervals. (3) When combined with HA rhinoplasty, relaxing the nasalis first makes filler results more natural. Patients with pronounced flare should consider Coretox + HA combination.
Will nasal Coretox affect breathing? Will my nose feel weird?
With proper dosing there’s no effect on breathing — the key is dose and placement: (1) Dose — standard nasal dose is 3-5 units per side, only relaxing the nasalis alar part, far below the threshold affecting breathing. The alar nasalis primarily functions to expand nostrils during expression, not in daily nasal airflow. (2) Placement — Rappoel precisely injects the upper lateral nostril nasalis, avoiding the nasal dilator muscle and nasal mucosa — no effect on nasal airflow. (3) Effect — after proper treatment, breathing remains completely normal — nostrils simply no longer flare excessively during smiling. (4) Risk — if excess spreads to the levator labii superioris alaeque nasi, temporary upper lip stiffness may occur, resolving in 4-6 weeks. Rappoel starts standard, preferring under-treatment.
What is the difference between Coretox nasal flare reduction and surgical nostril reduction? Which should I choose?
They solve different problems with different scopes: (1) Coretox nasal flare reduction — is ‘dynamic improvement,’ relaxing the nasalis to reduce nostril expansion during smiling. Suitable for: pronounced dynamic flare (only wide when smiling), normal static nostrils, those not wanting surgery. Non-surgical, no recovery, instant, reversible, but only improves dynamic flare without narrowing static nostril width. Lasts 3-4 months. (2) Surgical nostril reduction — is ‘static narrowing,’ removing tissue to permanently narrow nostril width. Suitable for: clearly wide static nostrils, wide both at rest and when smiling. Requires surgery, has recovery (1-2 weeks), permanent. Rappoel recommends: (1) If flare is only visible when smiling → Coretox effectively improves. (2) If nostrils are very wide at rest → surgery needed, Coretox has limited effect. (3) If both static width and dynamic flare → Coretox for dynamic first, then assess surgical need.
How fast does nasal Coretox work? When is the effect most visible?
Coretox nasal treatment timeline: (1) 2-3 days — onset begins, nostril flare reduction starts during smiling. (2) 5-7 days — visibly reduced flare, nose looks more refined when smiling. (3) 2 weeks — optimal results, minimal flare. (4) 3-4 months — effect gradually diminishes, nasalis activity returns, re-injection possible. Note: avoid lying flat or massaging for 4 hours after injection (prevent medication migration); avoid testing by forceful nose wrinkling or nostril flaring for 1 week (accelerates metabolism). For optimal state before important events, inject 2 weeks in advance.
Besides Coretox, what else can improve nasal flare?
Nasal flare treatment depends on cause and severity: (1) Pure dynamic type (only flares when smiling) — Coretox 3-5 units per side effectively improves. (2) Dynamic + low bridge type — Coretox + HA nasal bridge filler; elevating the bridge visually narrows nostrils. (3) Dynamic + bulbous tip type — Coretox + HA nasal tip sculpting. (4) Static wide nostril type — may need surgical nostril reduction, Coretox as adjunct for dynamic improvement. (5) Asymmetric type — unilateral Coretox fine-tuning. Rappoel assesses nasalis activity, static nostril width, and bridge height during consultation; most dynamic flare can be improved non-surgically with Coretox.
