Submental Fat Reduction · Product-Specific Review
V-OLET
Deoxycholic Acid Injection for a Defined Jawline
V-OLET uses deoxycholic acid to reduce localized fat under the chin. Noticeable swelling is expected, so planning matters for overseas patients. It is not a general weight-loss treatment. If the main concern is skin sagging rather than fat, a lifting treatment may be better suited.

Results Over Time
V-OLET is a deoxycholic acid injection that targets localized fat under the chin. It may improve the appearance of a double chin and create a more defined transition between the lower face and neck.
1Same day
Swelling, redness, or a firm sensation may occur under the chin. The area can look fuller temporarily from post-treatment swelling.
2Week 1
Swelling and tenderness begin to improve. The treated area may still feel firm, and visible swelling can continue during this period.
3Weeks 4–6
The under-chin area gradually looks more refined. Additional sessions may be discussed depending on remaining fat volume.
4Months 2–3+
Evaluated after the final session. Jawline and under-chin definition appear more improved depending on your skin elasticity.
5Long-term
Results can be relatively long-lasting when weight remains stable. Aging and natural skin laxity may affect the contour over time.
V-OLET
V-OLET is a deoxycholic acid injectable that targets localized submental fat. At Delight Dermatology, treatment is planned through a dermatologist-led consultation to determine whether your double-chin concern is mainly fat, skin laxity, facial structure, or a combination.
Adipocytolysis
Deoxycholic acid causes adipocytolysis in injected adipose tissue and may reduce localized submental fullness.
Separate laxity assessment
Reducing localized fat does not guarantee skin tightening. Skin laxity and facial structure require a separate in-person assessment.
Product-specific verification
Confirm the exact product name and current Korean authorized indication against the primary product record before treatment. This is not a weight-loss treatment.
Treatment Process
1Consultation
A dermatologist assesses your submental fat volume, skin elasticity, and goals, and whether V-OLET is the right route.
2Jawline Design
Injection points are mapped precisely for a defined jawline, protecting surrounding nerves and vessels.
3V-OLET Injection
Deoxycholic acid is injected into the targeted submental fat compartment under ultrasound guidance.
4Aftercare & Guidance
You receive detailed guidance on the expected swelling course and recovery before leaving.

- Injections are spaced evenly within the marked area.
- A fine needle goes in perpendicular to the skin.
- The needle tip sits at mid-depth in the fat under the skin.
- The injection is delivered into the fat layer.
Recovery & Care
First 24 hours
Swelling is expected and may be noticeable under the chin. Avoid heat (sauna, hot baths), strenuous exercise, and alcohol. A cold compress eases discomfort.
Days 1–3
Swelling may become more visible before gradually improving. A chin compression strap can help with comfort.
Week 1
Swelling, firmness, or tenderness may continue but usually improves over time. Sessions are spaced 4 weeks apart.
Ongoing care
Final changes should be evaluated gradually, not immediately. Maintain a stable weight: remaining fat cells can enlarge with significant weight gain.
Frequently Asked Questions
Q.How many sessions will I need?
Typically 3-5 sessions spaced 4 weeks apart. The dermatologist reassesses after each session, as individual fat distribution and response vary significantly.
Q.Does V-OLET permanently prevent a double chin?
No lifelong contour result can be guaranteed. Deoxycholic acid causes adipocytolysis in treated tissue, but published trial follow-up is limited and remaining adipocytes can enlarge. Weight change, aging, and skin laxity may alter the contour, so response and any future treatment should be reassessed in person.
