Introduction

What if we told you that those fine lines across your forehead and the crinkles at the corners of your eyes aren’t necessarily signs of aging you have to accept? At Yujin Plastic Surgery & Dermatology in Gangnam, we often hear patients say, "I want to look refreshed, not frozen." That desire for natural, expressive beauty is exactly where Botox excels—especially when treating forehead wrinkles and crow’s feet.

What Botox Really Does (It’s Not About Freezing Your Face)

Let’s clear up a common misunderstanding: Botox doesn’t erase wrinkles by filling them in. Instead, it works by calming the muscles beneath your skin. Over time, repeated facial expressions—like raising your brows or squinting in the sun—cause grooves to form in the skin. Botox gently reduces the movement in these specific muscles, allowing the overlying skin to smooth out.

At Yujin, we think of it more like guiding your expressions—not erasing them. You’ll still smile, frown, and look surprised, but with fewer lines left behind. Botox, derived from botulinum toxin type A, has been safely used in aesthetic medicine for over two decades. It’s FDA-approved and widely regarded as one of the most effective non-surgical methods for facial rejuvenation.

Botox’s mechanism of action is highly targeted: it temporarily blocks the nerve signals that trigger muscle contractions. This subtle muscle relaxation softens the appearance of dynamic wrinkles and prevents them from deepening. It’s a minimalist approach that yields maximal results—when done right.

Why Forehead Lines and Crow’s Feet Respond So Well

Forehead wrinkles and crow’s feet are both dynamic wrinkles—meaning they’re caused by motion. That makes them especially responsive to Botox.

• Forehead lines form when the frontalis muscle repeatedly lifts the brows. Over time, this motion etches horizontal lines across the forehead, especially in individuals who are expressive or who compensate for drooping eyelids.

• Crow’s feet develop from the orbicularis oculi muscle around the eyes contracting during smiling, laughing, or squinting. Sun exposure and thinning skin can accelerate this process, especially in climates like Korea’s with strong seasonal sun.

Botox relaxes these muscles just enough to soften their grip on the skin. Most patients begin noticing improvement within 3–5 days, with full results in about 10–14 days. The treatment itself takes less than 10 minutes and requires no downtime, which makes it ideal for busy professionals and first-time patients.

Another reason Botox works so well in these areas is because the skin is relatively thin, which allows even small doses to create visible smoothing. When paired with proper skincare—like sun protection and hydration—the results are often even more striking.

How Much Is Too Much? (This Is Where Experience Matters)

To be honest, one of the biggest concerns patients share is the fear of looking overdone. That’s why every Botox session at Yujin is personally performed by Dr. Tae-jo Kang. His deep understanding of facial anatomy—and his philosophy of natural enhancement—means you won’t walk out with a "frozen" forehead or an emotionless stare.

Dr. Kang customizes the number of units based on your muscle strength, facial balance, and aesthetic goals. For example:

• A patient in her 30s with early signs of crow’s feet may only need a small, preventive dose.

• A man with deep forehead grooves from years of expression might need a more tailored approach to achieve balance without heaviness.

The key is moderation, technique, and knowing exactly where to place each drop. Even within a small area like the forehead, injections must be placed with care to avoid unwanted eyebrow drooping or unnatural flattening. That’s why artistic judgment and anatomical precision are crucial. Yujin’s one-doctor approach ensures your results are consistent and safe.

We also take the time to assess each patient’s muscle movement patterns. Some people have strong lateral brow activity or asymmetrical expressions that require strategic balancing. These are subtle nuances that can’t be addressed with a one-size-fits-all dose.

How Long Do Results Last?

On average, Botox results last 3–4 months. Some patients report longer-lasting effects with consistent treatments, as the muscles gradually become trained to relax. That said, we never push patients into automatic touch-ups. At Yujin, our goal is to empower you with choices, not schedules.

Here’s what many people overlook: Botox isn’t just about today’s wrinkles. When done correctly, it can also prevent deeper lines from forming by interrupting the repetitive muscle activity that causes them. Think of it as investing in your future skin. Patients who begin Botox in their late 20s or early 30s often maintain smoother skin over the long term, even as they age.

It’s worth noting that longevity can vary depending on metabolism, lifestyle, and muscle strength. Athletes, for instance, may metabolize Botox faster. We always provide follow-up care and encourage patients to return when movement begins to reappear—rather than on a rigid calendar.

What Makes Botox at Yujin Different?

It’s not just the product—it’s the philosophy.

Many clinics in Seoul offer Botox. But at Yujin, every treatment is grounded in continuity and customization. You’re not passed from one technician to another. Dr. Kang personally handles each injection, drawing from over 15 years of experience in facial anatomy, aesthetics, and regenerative care.

We also consider how Botox fits into your broader aesthetic goals. Are you combining it with fat grafting for deeper rejuvenation? Planning a stem cell-based anti-aging program? At Yujin, Botox isn’t a one-off—it’s part of a cohesive, long-term vision for your skin health.

In some cases, we may recommend combining Botox with energy-based treatments like RF microneedling or laser toning to address texture, pore size, and pigmentation. When muscle relaxation is paired with skin strengthening, the results are more comprehensive and longer-lasting.

And here’s another detail many patients overlook: not all Botox is the same. We only use authentic, internationally approved formulations—never counterfeit or diluted versions. This ensures safety, consistency, and optimal results every time.

Patient Experience: What to Expect Before and After

Your first Botox consultation at Yujin begins with a detailed facial analysis. Dr. Kang will assess your expression patterns, skin quality, and any existing asymmetries. He’ll also ask about your aesthetic goals—whether you prefer a smoother look, more youthful eyes, or simply a bit of preventive care.

On the day of treatment, most patients describe the injections as a quick, pinching sensation. We can apply numbing cream for added comfort, but many patients find it unnecessary. There’s no downtime, though minor redness or swelling may occur briefly. You can return to work, apply makeup, and resume daily life right away.

Post-treatment, we recommend avoiding strenuous exercise, alcohol, and facial massages for 24 hours. Results begin to appear within a few days and continue to improve over two weeks. At Yujin, we always offer a follow-up appointment to ensure symmetry and satisfaction.

Most importantly, we listen. If you prefer ultra-subtle results or want to treat only one area, we’ll adjust accordingly. That’s the advantage of personalized, one-doctor care: your goals always come first.

Ready for a Softer, More Rested Look?

If your forehead lines are making you look more stressed than you feel—or if crow’s feet are giving away your age—Botox may be a gentle place to start. Especially when it’s delivered with care, precision, and a focus on natural results.

At Yujin, we believe aesthetic treatments should feel like a return to yourself—not a transformation into someone else. Whether you’re exploring Botox for the first time or returning for maintenance, you’ll receive expert guidance, honest feedback, and results that reflect who you are.

And if you’re wondering whether your treatment will be personally performed by a seasoned expert, we invite you to experience the one-doctor approach at Yujin.

Because subtle confidence isn’t something you manufacture. It’s something you restore—with intention.
