Combining Chin Filler with Jaw Slimming for a V-Line

Why two treatments create a V-line

A V-line look depends on the balance between the width of your lower face and the length and projection of your chin. Chin filler works on the tip: hyaluronic acid adds volume to lengthen a short chin and improve the side profile (the E-line running from nose to chin). But if the jaw corners are wide because the chewing muscle is bulky, adding chin volume alone can still leave the face looking square from the front.

That is where jaw-muscle slimming comes in. A relaxing injection into the masseter gradually reduces muscle bulk over several weeks, narrowing the lower face at the corners. Together, a projected chin and narrower jaw angles produce the tapered V shape. The two act on different tissues, so they are commonly planned as one combined approach rather than competing options.

Treatment order and timing

In practice the two are often scheduled thoughtfully rather than blindly stacked. The muscle-relaxing injection takes effect over roughly two to four weeks and continues to slim over the following month, so the final jaw width is not visible on the day. Chin filler, by contrast, shows an immediate change, with the shape settling as swelling eases over the first several days.

Because of that difference, some plans place the filler first so projection can be assessed against your current face, while others begin muscle slimming and refine chin volume once the jaw has narrowed. Your practitioner in Seomyeon will look at your bone structure, muscle bulk, and goals before deciding the sequence. The plan is personalised — there is no single fixed order that suits everyone.

Recovery, longevity, and cost

Downtime is modest for both parts. Chin filler typically leaves only mild bruising or swelling for a few days, with numbing cream used for comfort and a treatment time of roughly ten to twenty minutes. The muscle-relaxing injection is quick and usually needs no downtime, though effect builds gradually. Chin filler tends to last around six to eighteen months because the chin moves little, while muscle slimming generally lasts a few months per session and is repeated to maintain the result.

Because a combination is tailored to how much volume and how much slimming you need, exact figures depend on your plan. You can view current pricing on our clinic price board or ask during your consultation, where the full combination is quoted transparently before anything is done.
