✅ What it is

• The area just under the eyes can develop fine lines and muscle-rippling (often when smiling, squinting or due to eyelid muscle contraction).
• The treatment involves injecting a neuromodulator (botulinum-toxin type A) into targeted superficial muscle fibres beneath the lower lash line (often part of the orbicularis oculi muscle) to relax movement and smoothing the appearance of those lines.
• Important: This is not a filler or volume replacement. It does not fill hollows, remove dark circles from volume loss, or correct large under-eye bags — it primarily treats dynamic movement lines.
• Because the under-eye area is delicate (thin skin, important nearby anatomy like eyelid muscles and orbital rim), precision is critical.

⚙️ Procedure & what to expect

• Consultation: Practitioner assesses your under-eye area: how strong the muscle movement is when you smile/squint; the depth of lines; whether volume loss or fat bulge is present; skin quality; and your goals (e.g., “reduce visible lines when smiling”, “smooth under-eye motion”).
• Injection session: A small number of very fine injections placed in carefully selected points under the lower lash line or just beneath; session may take ~5 to 15 minutes.
• Timeline:
• Effect starts: often within 3–7 days.
• Full visible effect: around ~1–2 weeks.
• Duration: commonly 3–4 months, sometimes up to ~5 months depending on individual, muscle activity, brand and dosage.
• Downtime: Minimal. You may have slight redness or tiny pin-prick marks; you can usually resume most normal activity soon after. Avoid heavy rubbing or massage of the treated area for a short period.

💰 Typical cost range in Seoul

• Because this is a more delicate and specific area, cost can vary widely depending on brand of neuromodulator, number of units, injector experience, clinic location, and whether the procedure is combined with other under-eye treatments.
• Broad approximate range: from roughly ₩ 200,000 - ₩ 600,000 KRW for a standard under-eye smoothing session.
• For more comprehensive under-eye treatment (e.g., smoothing + muscle reduction + minor puffiness control) cost may go higher—up to ~₩ 600,000-₩ 1,000,000 KRW in some cases.
• Because this treatment is less common and more technical than e.g., forehead or crow’s feet Botox, make sure to ask exactly “units used”, “brand”, “what follow-up is included”.

🧐 What to ask / check before you proceed

• Which brand of neuromodulator will be used and whether it’s certified for that area.
• How many units/dose will be used for your under-eye region and why that dose was chosen (based on your muscle activity, line depth, anatomy).
• The injector’s experience with under-eye/fine-line injections—given the delicate anatomy (lid margin, orbicularis muscle, fat pads) you want someone skilled.
• Whether underlying issues exist (hollowing, fat bulge, skin laxity) that may limit results with just Botox and might require complementary treatments (fillers, laser, microneedling).
• After-care instructions: e.g., avoid pressing or massaging under-eye area for a set time; any activity restrictions.
• Realistic expectations: Understand that Botox will reduce movement-lines but will not fill hollows, remove heavy bags, or dramatically change structure.
• Maintenance plan: Ask how long they expect the result to last for you and when you might return for a top-up.
• Full cost breakdown: Are consultation, injections, follow-up included? What happens if you want additional units or a touch-up?

📋 Smart tips & after-treatment care

• After treatment: Avoid rubbing, massaging or pressing the under-eye region for at least 24 hours (or whatever your clinic advises).
• Avoid strenuous exercise or extreme heat/sauna in the first day if recommended to minimise swelling/bruising.
• Keep skin well-hydrated and protected (under-eye skin is thin and sensitive). Use gentle skincare routines.
• Use sun-protection around eye area. UV and sun-damage contribute to under-eye lines.
• If you notice hollowing or volume loss emerge over time under your eyes, discuss with your practitioner—Botox addresses muscle movement but not volume/fat loss.
• Keep a record of brand, units and date of treatment, so your next session can be consistent in approach.
