A forehead reduction shortens a high forehead by advancing the hairline forward, so the incision runs along the hairline and the forehead skin is moved and re-fixed. The swelling reflects that: puffiness in the forehead drifts downward with gravity into the eyelids and around the eyes over the first days, while the hairline incision itself settles. That is normal, and it follows a predictable arc — it peaks early, eases over the following weeks, and a handful of measures genuinely speed it along. This guide maps that week-by-week recovery and flags the signs worth an urgent call.
Garnet is well known for neck-wrinkle and lifting surgery. The facility is excellent and I’m thoroughly satisfied with the friendly consultation and the surgeon’s skill.
Director Baek In-soo, thank you so much. Thanks to you I keep getting told I look younger — it feels like I’ve gone back to my younger days.
I had upper and lower eyelid surgery and I’m really satisfied. The director and the manager were both so kind and clear.
I started with under-eye fat repositioning — the director and the manager are genuinely kind and good at what they do. I’ll be back.
I came on a referral and was very satisfied thanks to the doctor’s kind consultation and clear explanations. The nurses were friendly too.
I kept reading the reviews and came trusting the many mentions of skill and kindness. The clinic was busy with patients and spotless.
A forehead reduction lowers a high forehead by advancing the hairline: the surgeon makes an incision along the hairline, releases the forehead soft tissue, moves the hairline-bearing scalp forward and re-fixes it, then closes so the incision sits at the new hairline. Because the whole forehead layer is lifted, moved and re-anchored across a broad area, the forehead responds with real, expected swelling — the operation is about repositioning tissue, not just the incision line.
Swelling also obeys gravity, and this is what surprises people most. Fluid that builds in the forehead does not stay put; it drifts downward over the first days into the eyelids and around the eyes, so it is normal for the eyes to look puffy, heavy or even faintly bruised even though the surgery worked higher up along the hairline. The forehead itself can feel tight and firm while the eyes carry much of the visible swelling.
Understanding this makes the early days far less alarming. The puffy eyes and tight forehead of the first days are swelling settling downward, not the final look — which is why the reduced forehead and new hairline are judged over weeks, not days. We map the full arc in the recovery timeline and cover the long view in when you will see results.
Days 1–4: swelling builds and peaks, usually around days two to four, and is at its most visible — often more so around the eyes than along the hairline as fluid settles downward. The forehead feels tight and firm, the hairline incision is dressed early on, and any bruising around the eyes appears and darkens. This is the window to be strict about head elevation, gentle cooling and rest. It is normal to look quite puffy and not yet to appreciate the reduced forehead.
Week 1–2: swelling begins a steady decline and any eye bruising shifts from dark to green-yellow as it fades. The hairline sutures or staples are typically checked and removed within the first couple of weeks — your surgeon confirms the exact timing for your closure — which also serves as a check that the incision and swelling are settling as expected. By the end of week two, many people look markedly better than the peak, though the forehead may still feel tight and the hairline is still healing.
Weeks 3–6 and beyond: the swelling others would readily notice keeps resolving, and by around three to six weeks most patients feel comfortable in normal social settings. What remains after that is subtle and slow: a residual tightness across the forehead and along the hairline, occasional numbness or altered sensation behind the incision as small nerves recover, and a settling of the forehead and hairline that continues over the following weeks. It is normal for the two sides to de-swell at slightly different rates before evening out.
Bruising after a forehead reduction often behaves in a way people do not expect: because the incision sits up along the hairline, that area may show less obvious bruising, while the eyelids and area around the eyes carry more of it as blood and fluid settle downward with gravity. So it is common to see puffy, faintly bruised lower lids and under-eyes even though nothing was operated on there. This downward migration is normal and not a sign of a problem.
Like any bruise it changes colour as it clears, moving from dark red-purple through blue, green and yellow before fading. Most bruising settles within two to three weeks, roughly in step with the bulk of the swelling. Keeping your head elevated and cooling gently in the first 48 hours both help limit how far it spreads and how long it lasts; once the eye-area bruising has faded enough, makeup can usually cover what remains, on your surgeon's timing.
A few everyday factors make bruising worse: blood-thinning medication and supplements such as fish oil, high-dose vitamin E, ginkgo and certain anti-inflammatories; alcohol around the time of surgery; and high blood pressure or straining. Disclosing every medication and supplement at your consultation and following the pre-surgery guidance is the simplest way to keep bruising down — we cover the comfort side of recovery in pain and anaesthesia and how the hairline incision heals in scars and healing.
The measures that genuinely help are simple and worth doing consistently. Keep your head elevated, including sleeping propped up at around 30–45 degrees for the first one to two weeks, so fluid drains from the forehead and eyes rather than pooling — facial swelling is almost always worse on waking and elevation blunts that, which matters especially here because the puffiness gathers around the eyes overnight. Cool the area gently in the first 48 hours with cool compresses across the forehead and around the eyes as your surgeon directs, never ice directly on the skin and never firm pressure over the hairline incision.
Rest and pace yourself. Avoid strenuous activity, heavy lifting, bending over and anything that raises blood pressure for the first two to three weeks, since all of it feeds forehead and eye swelling and can worsen bruising or, rarely, bleeding — and tension across a fresh hairline incision is best avoided. Keep your blood pressure steady and take calm, low-effort days early on. Skip alcohol and smoking, which impair healing and worsen swelling, stay well hydrated, and keep salt low to discourage fluid retention around the eyes.
Beyond that, follow the specifics your surgeon gives you: how to wash your hair around the hairline incision, when the closure feels secure enough to move more freely, and when light activity and then exercise are safe. None of these are dramatic alone, but together they shorten recovery — which matters most for international patients recovering within a planned trip, and is part of the broader picture in recovering in Seoul after surgery.
Normal, expected recovery: swelling peaking in the first two to four days and easing over the following weeks; puffiness and faint bruising around the eyes as fluid settles downward, clearing over two to three weeks; tightness across the forehead and along the hairline, numbness or altered sensation behind the incision, and a heavy-feeling forehead that softens over weeks; and slight differences between the two sides early on. None of this needs intervention — it is a forehead reduction healing as it should.
What warrants an urgent call is anything that breaks sharply from that path: rapidly increasing, tense swelling on one side of the forehead, especially if firm and painful (a possible collection that needs prompt review); severe or escalating pain not eased by your prescribed medication; a sudden change in skin colour over the forehead or hairline; fever or spreading redness, warmth or discharge along the hairline incision suggesting infection; or any wound edge that looks like it is separating. Sudden, marked one-sided forehead swelling in the first day or two is the classic reason to contact the clinic without delay rather than wait.
The reassurance that matters most is being able to reach the surgeon who actually performed the operation. If you can send a photo and get a same-person answer on whether your swelling, bruising and hairline incision are on track — or be told to come in — you are not left guessing, which is especially valuable once you have travelled home.
Garnet is a single-surgeon clinic in Apgujeong, Seoul. Dr. In-Soo Baek is a board-certified plastic surgeon (Korean medical licence no. 77407) and the only operating doctor — he performs the hairline-advancement forehead reduction and reviews your recovery himself, so the person assessing your swelling is the person who did the surgery. The clinic keeps the day light, with unhurried time and clear after-care guidance for an operation whose swelling shifts around to the eyes while a hairline incision heals.
Aftercare covers exactly the measures above — elevation, gentle cooling of the forehead and eyes, rest, blood-pressure care and what to avoid — and the incision check and suture or staple removal within the first couple of weeks doubles as a check that the hairline and swelling are settling on track. Garnet runs structured follow-up at one, three and six months, which suits how the forehead and hairline settle over time, and for international patients much of this happens by messenger: you send a photo and the same surgeon confirms your recovery is on course or flags anything that needs attention.
If you are still deciding, start with a no-obligation online assessment: send clear photos and the surgeon will give an honest view of what recovery — including how much swelling and eye-area bruising to realistically expect, and how long to stay — would look like for you.
Send photos and your question before you travel. An English-speaking coordinator reviews every enquiry and replies with honest guidance on whether surgery is appropriate, the likely plan and timing.
