Masseter Botox vs Facial Contouring Injections: Which Is Better?

A slimmer, more balanced face shape is one of the most common goals for visitors to Gangnam. Two popular non-surgical approaches are masseter Botox and facial contouring injections. They sound similar but work in very different ways, so the right choice depends on what is making your face look wide or unbalanced.

1. How masseter Botox works

Botox injected into the masseter muscles at the back of the jaw relaxes them. When a strong chewing muscle is the main reason the lower face looks square, the muscle gradually becomes smaller over four to eight weeks, and the jawline looks softer and more tapered. It reduces width — it does not add shape anywhere.

2. How contouring injections work

Contouring injections use fillers or other injectables to reshape specific points of the face — for example projecting the chin, defining the jawline angle, softening flat temples or balancing the cheeks. Rather than reducing size, they create structure and improve proportions. At MIN Clinic, contour plans are designed around the whole face rather than one feature.

3. Which concern suits which?

Wide, square lower face from muscle: masseter Botox.

Short or recessed chin: chin filler or contour injection.

Undefined jawline with little bone projection: contour injections.

Flat temples or uneven cheeks: contour injections.

Fullness from fat along the jaw: ONDA rather than either option.

Many faces benefit from both — slimming the jaw with Botox and adding a little chin projection with filler can create a balanced V-line.

4. Results and longevity

Masseter Botox results appear gradually over four to eight weeks and typically last around three to six months, with repeat sessions maintaining the effect. Filler-based contouring shows results immediately, refined as swelling settles, and typically lasts around nine to fifteen months.

5. Downtime

Masseter Botox has almost no downtime; small injection marks fade within hours. Contour injections may cause mild swelling or small bruises for a few days, so they are best scheduled early in a trip.

6. Cost in Seoul

At MIN Clinic, masseter Botox typically costs around KRW 300,000 to KRW 700,000, and face contour injections around KRW 500,000 to KRW 1,800,000 depending on the areas and products. See our event price list.

7. Safety considerations

Both treatments should be performed by an experienced doctor who understands facial anatomy. Hyaluronic acid fillers can be dissolved if needed, which adds a layer of reassurance.

Conclusion

Masseter Botox reduces muscle bulk for a slimmer lower face, while contouring injections add structure and balance. The best plan often uses both. Send front and side photos to our English-speaking team on WhatsApp, or explore our face contour injections and Botox pages.
