A double chin is not a concern reserved for fuller faces. It can come from accumulated fat, but it also often develops as the skin loses elasticity with age and the area under the chin begins to sag. Different causes call for different approaches, so this article breaks down the roles that four treatments — Ultherapy, fat-dissolving injections, V-OLET, and V-line Botox — each play.
Start with the Cause, Not the Treatment Name
Volume under the chin generally comes from fat accumulation, reduced skin elasticity, or a combination of both. Rather than copying a treatment that is trending online, it is more sensible — for both results and cost — to first confirm which type your double chin is through a consultation with a doctor, and then choose only the treatments you actually need. We recommend choosing a clinic that guarantees a thorough one-on-one consultation before treatment, rather than one that applies the same package to everyone.
When Ultherapy and Fat-Dissolving Injections Are Combined
If your double chin involves some fat but is also driven by loss of elasticity, one option is to combine Ultherapy under the chin to tighten sagging tissue with fat-dissolving injections that support fat metabolism. At Skinique Clinic, the fat-dissolving injection is given first, followed by under-chin Ultherapy: the injected solution creates a favorable environment for the ultrasound's thermal energy to reach the tissue, so the two treatments complement each other. That said, the degree of response varies from person to person.
V-OLET: An Injection That Reduces the Number of Fat Cells
If fat accumulation is the dominant factor, a more direct approach to the fat itself is needed. V-OLET is an injectable approved by Korea's Ministry of Food and Drug Safety (MFDS) for improving submental fat, with deoxycholic acid (DCA) — a secondary bile acid naturally present in the body — as its main ingredient. Rather than temporarily shrinking fat cells, it dissolves the cell membrane and reduces the actual number of fat cells, which can help address volume under the chin.
The Three Components of V-Line Botox
If you want to refine not just the area under the chin but the overall facial line, Botox can be applied area by area. Masseter Botox reduces the bulk of an overdeveloped jaw muscle to set the starting point of the line, mouth-corner Botox gently lifts drooping corners of the mouth to soften the expression, and finally Dermotoxin — micro-injections placed closely along the jawline — smooths and connects the line. How many of the three areas to include depends on your face shape.
The Right Combination Is Decided in Consultation
You do not need all four treatments. Skinique Clinic's double-chin program works selectively: after a consultation with the doctor, only the items you need are chosen from Ultherapy, fat-dissolving injections, V-OLET, and V-line Botox. Detailed pricing is available on the price guide.
Wrapping Up
The starting point for improving a double chin is not a treatment name but identifying the cause. If reduced elasticity is the issue, Ultherapy with fat-dissolving injections; if fat accumulation is the issue, V-OLET; and if you want to refine the entire facial line, V-line Botox — the right combination depends on your type. If you are wondering which combination suits the area under your chin, feel free to ask via chat with us about the right direction for your face.
