This contour injection guide was compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes' walk from Konkuk Univ. Station, Exit 1).

The most frequent question in the contour injection consultation room is, "Will I lose weight with one injection?" The honest answer is, "Weight loss does not occur with a single injection; rather, the lines are refined cumulatively." The recommended medication, units, and frequency vary by area. Here's how we determine them in the clinic.

The term "contour injection" actually encompasses different groups of medications depending on the area and purpose.

• Facial contour injection — Refines facial lines such as under the cheekbones, deep cheeks, and double chin.
• Body contour injection — Refines body lines such as the abdomen, thighs, and arms.
• Area-specific medications — For areas with a lot of fat, areas with less fat, and for elasticity.

The lineup offered at SHINE U Clinic Konkuk is as follows:

Although they fall under the same contour injection category, the applicable areas and units differ, so the choice of medication varies depending on where it is used.

Facial contour injections are used to refine the lines under the cheekbones, deep cheeks, double chin, and side of the face.

Recommended for:

• Those who have lost weight through diet but whose facial lines remain unchanged.
• Those whose side profile has collapsed due to sagging skin under the cheekbones.
• Those whose double chin and side facial boundary have become blurred.
• Those who want to create a V-line in conjunction with square jaw Botox.
• Those who prefer cumulative refinement rather than a drastic change at once.

Perfect Injection is a standard contour injection, available in 2cc, 4cc, and 1 vial units. Millifit Injection is a premium line, available in 4cc and 1 vial units. The medication and dosage are determined based on the patient's area size and previous treatment history.

Recommended frequency: Once every 2-4 weeks for 3-5 cumulative sessions is typical. It is difficult to see a clear change with a single session; it is more accurate to understand it as a process where lines are refined cumulatively.

Facial contour injections can be performed alone, but when combined with square jaw Botox, V-line refinement is often more pronounced.

• Square jaw Botox — Reduces the volume of the masseter muscle → Refines the skeletal line of the side of the face.
• Facial contour injection — Refines the volume under the cheekbones, deep cheeks, and double chin.

Since the two procedures target different areas (muscle vs. fat), their results do not overlap and are complementary. This is a combo frequently recommended in the clinic.

Body contour injections are used for fat breakdown + line refinement. The medication varies by area.

Skinny S Injection — For areas with a lot of fat

Skinny S Injection is recommended for areas with a lot of fat, such as the abdomen and thighs. It is administered in 500cc units per session.

Body Line Cut Injection — For areas with less fat

Body Line Cut Injection is recommended for refining lines in areas with less fat, such as the arms, calves, love handles, and under the chin. It is administered in 20cc units per session.

Body Power Perfect Injection — Fat + Elasticity

Body Power Perfect Injection is a medication that addresses not only fat breakdown but also elasticity improvement. It is often recommended for those concerned about sagging skin after dieting.

Q1. "Will I lose weight with one contour injection?" A significant change with one session is difficult. Clear changes are usually visible in the mirror after 3-5 cumulative sessions at 2-4 week intervals. We recommend evaluating the results after completing the recommended number of sessions, rather than judging by a single session.

Q2. "Can I receive it with lifting procedures?" It is often performed in conjunction with Onda lifting and Titanium lifting. For stable recovery, it is better to avoid overlapping the two procedures on the same day and maintain a 1-2 week interval.

Q3. "Are fat-dissolving injections and contour injections the same?" Broadly speaking, they are in the same category, but the ingredients and mechanisms of action differ for each medication. In the clinic, the appropriate medication is determined based on the patient's area and treatment history.

Q4. "If I gain weight again after a contour injection, will the effect disappear?" If weight increases after the procedure, some areas may regain volume. The maintenance of contour injection results is directly linked to diet and exercise habits, so it is more accurate to view it as part of a lifestyle pattern rather than a standalone procedure.

Consult by chat now for each area

Common care for contour injections:

• Avoid strong massage or rubbing of the treated area on the day of the procedure.
• Temporary swelling, puffiness, or small bruises will improve within 3-7 days.
• Avoid saunas, strenuous exercise, and alcohol on the day of the procedure.
• Drink plenty of water after the procedure (helps excrete fat breakdown waste products).
• Remember to use sunscreen.

For body areas, light walking or massage for about a day after the procedure can help lymphatic circulation, which is beneficial for stable results.

Q. If I'm getting it for the first time, where should I start? We recommend starting with one area that bothers you most in the mirror. Starting multiple areas simultaneously can make it difficult to assess the results.

Q. When will I see results? Subtle changes are reported 1-2 weeks after the first procedure as swelling subsides. Clear changes are usually visible around the 3rd cumulative session.

Q. How much pain is involved in the procedure? It varies depending on the treated area. For the face, there is a mild sensation of stimulation; for the abdomen and thighs, the procedure time is longer, so the sensation of stimulation may accumulate somewhat. We apply anesthetic cream to alleviate discomfort before proceeding.

Q. Can I receive it during pregnancy? It is not recommended during pregnancy or breastfeeding. We advise proceeding after a sufficient recovery period following childbirth and the cessation of breastfeeding.

Contour injection is a process where lines are refined cumulatively rather than a drastic change at once. Since the recommended medication and units vary by area, we will determine the appropriate approach for your case together in front of the mirror. You can inquire directly via chat for non-face-to-face consultation.
