V-OLET Treatment in Seoul
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 suit better.
- Duration
- 20–30 min
- Sessions
- 3–5 (4-week intervals)
- Downtime
- 1–3 weeks swelling
- Peak Result
- 4–8 weeks per session
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.
01Same day
Swelling, redness, or a firm sensation may occur under the chin. The area can look fuller temporarily from post-treatment swelling.
02Week 1
Swelling and tenderness begin to improve. The treated area may still feel firm, and visible swelling can continue during this period.
03Weeks 4–6
The under-chin area gradually looks more refined. Additional sessions may be discussed depending on remaining fat volume.
04Months 2–3+
Evaluated after the final session — jawline and under-chin definition appear more improved depending on your skin elasticity.
05Long-term
Results can be relatively long-lasting when weight remains stable. Aging and natural skin laxity may affect the contour over time.

V-OLET Core Stack
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 permanently destroys fat cells so the treated fat cannot regrow — a durable reduction, not a temporary shrink.
Collagen Lifting
After fat destruction, V-OLET induces neocollagenesis — tightening under-chin skin to prevent sagging of the reduced tissue.
MFDS-Approved
The only MFDS-approved deoxycholic acid product for submental fat reduction in Korea, supported by Korean clinical trial data. Not a weight-loss treatment.
Treatment Process
01Consultation
A dermatologist assesses your submental fat volume, skin elasticity, and goals — and whether V-OLET is the right route.
02Jawline Design
Injection points are mapped precisely for a defined jawline, protecting surrounding nerves and vessels.
03V-OLET Injection
Deoxycholic acid is injected into the targeted submental fat compartment under ultrasound guidance.
04Aftercare & Guidance
You receive detailed guidance on the expected swelling course and recovery before leaving.
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 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 is V-OLET different from conventional lipolytic injections (known in Korea as 윤곽주사)?
V-OLET performs adipocytolysis — it permanently destroys fat cells so they cannot regrow. Conventional lipolytic injections only temporarily reduce fat cell size. V-OLET also induces neocollagenesis, producing simultaneous skin tightening. It is the only MFDS-approved deoxycholic acid product for submental fat reduction in Korea, with Korean clinical trial data supporting the approved indication.
Q.Is V-OLET permanent?
Yes — the destroyed fat cells do not regenerate. Results are durable as long as significant weight gain does not cause remaining fat cells to enlarge.
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.
