This is the SHINE V guide, compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes' walk from Konkuk Univ. Station, Exit 1).
When you see a photo where your jawline has been slimmed down with a beauty camera app, you might wonder if it's possible to achieve that in reality. This applies to men as well. We've put together information on how contour injection works to address the jawline and why a double chin forms.
A double chin that obscures the V-line
One of the factors that determines a slim face is a double chin. If a double chin is severe, the boundary between the face and neck can become blurred, tending to make the face appear larger.
Why does a double chin form?
There are two main causes:
- Accumulation of fat due to weight gain
- Sagging due to decreased skin elasticity from aging
Typically, in younger individuals, fat accumulation is often the cause, while in age groups where aging begins, skin sagging is often the cause.
If excessive double chin or cheek fat in youth is left unmanaged, it can exacerbate sagging later on, so it's better to manage it early.
How contour injection works
In the past, liposuction or incision was used for fat removal, but now many people are opting for contour injection, which reduces the burden and allows for a quick return to daily life.
Contour injection is a method that uses a specially formulated injectable to address fat cells and help excrete waste products, also known as a fat-dissolving injection.

Number of sessions and post-procedure care
Changes may not appear immediately after just one session. We recommend multiple sessions at weekly intervals, and massage for a few days after the procedure is important.
- We recommend 4 or more sessions at weekly intervals.
- Consistent massage for 3 days after the procedure.
- The effects and number of sessions may vary by individual.
Conclusion
Since facial bone structure, fat amount, and skin condition differ for each person, a holistic and harmonious approach is important. If sagging is also present, lifting may be combined, so please proceed after confirming your condition.
