Botox vs Filler: Which Treatment Do You Need?

October 7, 2026

Quick answer: Botox is better for lines caused by movement, such as frown lines, forehead lines and crow’s feet, and for slimming a square jaw. Filler is better for lost volume and shape: hollow under-eyes, deep folds, thin lips or a short chin. If a line is still visible when your face is relaxed, filler (or both) may be needed.

What is the difference between Botox and filler?

Botox is a botulinum toxin injection that temporarily relaxes the muscle it is placed in. When the muscle moves less, the skin above it creases less, so expression lines soften. It is also used to slim the masseter (jaw) muscle and relax the trapezius.

Dermal filler, in most Korean clinics, is a hyaluronic acid gel injected under the skin to add volume, lift and shape. It replaces lost volume, smooths folds and defines features like the lips and chin. Results are visible right away, and hyaluronic acid filler can be dissolved with hyaluronidase if needed.

So the core of the Botox vs filler question is simple: Botox changes movement, filler changes volume. Both are widely offered: Botox in Hongdae and dermal fillers in Seoul.

How to tell which treatment you need

Try this two-step mirror test before your consultation:

  1. Make the expression. Frown, raise your eyebrows, smile widely. Lines that appear only now are dynamic wrinkles, usually a Botox job.
  2. Relax completely. Lines, hollows or flat areas that remain at rest are static, usually a filler (or skin-quality) job.

Many people have both: a frown line that is partly etched in at rest, for example. In that case, a doctor may use Botox to stop the movement and a small amount of filler to soften what remains.

Which is better for each area of the face?

Area or concern Usually Botox Usually filler
Forehead lines Yes, for lines when raising brows Sometimes, for a flat or hollow forehead
Frown (“11”) lines Yes, first choice Occasionally for deep, etched lines
Crow’s feet Yes Rarely
Under-eye hollows No Yes, soft filler; or eye Rejuran for thin skin
Nasolabial folds No Yes
Lips Rarely, for a gummy smile or lip flip Yes, for volume and shape
Square jaw Yes, masseter Botox No
Short or receding chin No Yes, chin filler
Hollow temples or cheeks No Yes, or a collagen stimulator like Sculptra

For under-eye concerns, see our page on dark circle treatment in Seoul. For a slimmer, V-shaped lower face, the decision often comes down to jaw Botox vs chin filler, or a combination of both.

How long do Botox and filler last?

Botox usually starts working in 3–7 days, reaches full effect around 2 weeks and lasts about 3–4 months. Jaw Botox often lasts longer, and repeated treatments can gradually slim the muscle.

Hyaluronic acid filler is visible immediately, settles over 1–2 weeks as swelling fades, and typically lasts about 6–18 months depending on the product and area. Lips usually fade faster than the chin or cheeks. If you want gradual volume that lasts longer, compare options in Sculptra vs dermal fillers.

How much do Botox and filler cost in Seoul?

Approximate Seoul market ranges in 2026:

  • Forehead or frown Botox: about KRW 30,000–100,000 with a Korean toxin (roughly US$20–70), or KRW 100,000–250,000 imported (roughly US$70–180).
  • Jaw (masseter) Botox: about KRW 50,000–150,000 Korean, or KRW 150,000–350,000 imported.
  • Filler per 1cc: about KRW 100,000–250,000 Korean (roughly US$70–180), or KRW 250,000–500,000 for imported brands like Juvederm, Restylane or Belotero (roughly US$180–360).
  • Lip filler 1cc: about KRW 150,000–400,000; chin filler (1–2cc): about KRW 150,000–500,000.

Botox is usually the lower-cost entry point, but needs repeating more often. Filler costs more per visit and lasts longer. Price also depends on units or cc, Korean vs imported products, numbing, and the 10% VAT usually added to cosmetic procedures. These are market ranges, not any single clinic’s prices; check the current price list, and see our Botox cost guide and dermal filler cost guide.

Can you get Botox and filler on the same day?

Yes. Combining Botox and filler in one visit is very common in Korea, especially for foreigners with limited time. A typical combination is Botox for frown lines or crow’s feet plus filler for under-eyes, folds or the chin.

A doctor will plan the order and amounts so the result looks balanced. If you are unsure about filler, starting with Botox first is a low-commitment way to begin. And if filler is ever uneven, many Seoul clinics also offer filler dissolving injections.

Downtime and travel: what foreigners should plan for

  • Botox: almost no downtime. Avoid rubbing the area, saunas and intense exercise for 24–48 hours. Flying the next day is usually fine.
  • Filler: allow about 2–3 days for swelling and possible bruising, longer for lips. Book filler early in your trip, not the day before an event.
  • Both: Botox takes up to 2 weeks for full effect, so if you want a check-up, book soon after you arrive.

Tell the doctor if you are pregnant or breastfeeding, have recently had dental work or skin infections, or take blood thinners. For a wider overview of treatments, see the complete guide to skin treatments in Korea for foreigners.

Planning your visit to a skin clinic in Hongdae, Seoul

Botox and filler both fit easily into a short trip. Hongik Univ. Station is on Seoul Subway Line 2, the Gyeongui–Jungang Line and the AREX Airport Railroad, with direct trains to Incheon and Gimpo airports.

  • Ask whether English- or Japanese-speaking staff are available.
  • Many clinics take consultations by WhatsApp or KakaoTalk; send relaxed and expression photos plus your travel dates.
  • Confirm who performs the treatment, the product brand, the exact units or cc, and whether VAT is included.
  • Check the clinic’s current Hongdae clinic price list before you book.
  • Leave a buffer before your flight, since filler swelling can take 2–3 days to settle.

Frequently asked questions

Is Botox or filler better for wrinkles?

It depends on the type of wrinkle. Botox is better for dynamic wrinkles that appear with expressions, such as frown lines, forehead lines and crow’s feet. Filler is better for static lines and folds caused by volume loss, such as nasolabial folds. Many people benefit from a small amount of both.

Which lasts longer, Botox or filler?

Filler usually lasts longer, about 6–18 months depending on the product and area. Botox typically lasts about 3–4 months for wrinkles, and often longer for the jaw. Because of this, Botox is repeated more often, while filler touch-ups are needed less frequently.

Does Botox or filler hurt more?

Filler is usually a little more uncomfortable because more product is injected and some areas, like the lips, are sensitive. Numbing cream is commonly used, and many fillers contain lidocaine. Botox involves a few quick pinches and is over in minutes. Most foreigners find both very manageable.

Can I get Botox and filler on a short trip to Seoul?

Yes. Both can be done in one visit, often in under an hour including numbing. Plan filler at least 2–3 days before flights with important events or photos to allow swelling to settle. Botox has almost no downtime, and flying the next day is usually fine.

Should I start with Botox or filler if I am a first-timer?

Many first-timers start with Botox for expression lines because it is quick, has minimal downtime and wears off naturally. If your main concern is hollowness or shape, filler may be the right first step. A doctor can assess your face and suggest the most effective, conservative plan.
