Information as of June 2026

Selection Criteria by Insertion Site and Material

• Over 8 Types of Implants
• Average Fat Survival Rate 60-80%
• 30% Difference in Tactile Sensitivity by Insertion Site

Most Frequently Asked Question in the Clinic: 'Which Method Is Right for Me?'

During consultations, 70% of patients ask about 'comparing breast augmentation types' first. However, in most cases, they have never actually measured their own breast tissue thickness or chest width. The choice of method is determined first by anatomical conditions, not by the desired size. According to data from the Korean Society of Plastic and Reconstructive Surgeons in 2023, 83% of breast augmentation surgeries in Korea use implants, 12% use fat grafting, and 5% use a combination method. However, these ratios reflect the distribution of 'fitness' rather than patient preference. In this article, we compare the three methods—including insertion location, materials, recovery, and cost—using 15 years of clinical data. To find your case, first check three things: tissue thickness, chest shape, and lifestyle patterns. Key Points If breast tissue thickness is less than 15mm, consider submuscular insertion; if 20mm or more, consider supramuscular or fat grafting — Deciding the method without measurement lowers tactile satisfaction by 30% Implant Breast Augmentation: Insertion location determines 60% of the result figure class="lumi-section-figure">

Implants are divided into three types depending on their position: supramundane (submuscular), submuscular (below the pectoralis major), and dual plane (the upper part is below the muscle, and the lower part is below the mammary gland). Each has different tactile sensations, capsular contracture rates, and recovery periods.

Supramuscular implants recover quickly (2 weeks) and have a natural shape, but if the tissue is thin, the contour of the implant can be felt. The FDA 2022 report presented capsular contracture rates as 12% for supramundane implants and 8% for submuscular implants.

Submuscular implants have a softer tactile sensation and a lower capsular contracture rate, but pain due to pectoralis major dissection is significant (4 weeks), and there is a possibility of implant displacement in active occupational groups. Dual-plane implants combine the advantages of both but require an experienced surgeon due to the high surgical difficulty. The material of the implant is also important. Cohesive gel (high-cohesion silicone) offers excellent shape retention but feels slightly firm to the touch. Teardrop-shaped implants (anatomical implants) create a natural slope but carry a risk of asymmetry during rotation, making a textured surface essential. Products commonly used in Korea include Mentor Memory Gel, Motiva Ergonomics, and Sebbin Round. As of 2020 KFDA approval standards, all have secured long-term safety data spanning over 10 years. Clinical Results: When selecting implants, hospitals that measure not only tissue thickness but also chest width, nipple position, and degree of asymmetry using 3D CT show a 25% higher satisfaction rate with the results.

Fat Graft Breast Augmentation: Survival Rate and Number of Repetitions Are Key Variables

Autologous fat grafting involves injecting fat harvested from the abdomen or thighs into the breasts after centrifugation. Unlike implants, it does not feel foreign and has a natural texture, but the amount injected per session is limited (50-150cc per side).

The average fat survival rate is 60-80%. Since 20-40% is absorbed over the 3 months following injection, 2-3 repetitions are generally required to achieve the desired volume. According to a 2021 study by the Korean Society of Aesthetic Plastic Surgery, the satisfaction rate with a single procedure was only 35%. The incidence of calcification and cysts is reported to be 5-15%. Over-injection leads to necrosis and calcification of the central fat, which can cause confusion during mammography, so caution is advised for patients over 40. Although there are studies suggesting that the engraftment rate increases by 10-15% when combined with SVF (Stromal Vascular Fraction, a stem cell concentrate), it has not yet received approval from the Ministry of Food and Drug Safety in Korea. Currently, mixing with PRP (Platelet-Rich Plasma) is a legal alternative. Fat grafting is not suitable for those seeking an enlargement of 1-2 cup sizes or more, or for those with very thin breast tissue who are concerned about the contours of the implants. Instead, it is effective for slight volume correction or contour enhancement after implant surgery. Caution: Mammography interpretation is difficult for 6 months after fat grafting. If you are over 40 or have a family history, be sure to complete a breast examination before the procedure.

• Average fat engraftment rate 60-80%, individual variation ±20%
• Single injection volume 50-150cc unilateral, repeated 2-3 times generally
• Incidence of calcification 5-15%, increases with over-injection
• Reported 10-15% increase in engraftment rate when combined with SVF

Combined Breast Augmentation: Synergy and Risks of Implants + Fat Grafting

The combined method is a two-step approach in which basic volume is created with implants, and the contour is refined with fat grafting 3 to 6 months later. Fat is added to the upper area where the implant contour can be felt, or in the axillary crease, to enhance naturalness. A 2020 study in the Aesthetic Surgery Journal showed that the combined method offered 28% higher tactile satisfaction and a 12% lower reoperation rate compared to a single implant. However, total costs increased by 1.8 to 2 times, and the recovery period doubled. It is important to note that injecting fat immediately after implant insertion increases the risk of capsular contracture. Fat grafting should be performed after a minimum interval of 3 months has passed and the tissue has stabilized. The combined method is suitable for those who desire a large size despite having thin breast tissue, or for those with a lean physique who are concerned about the implant contour. On the other hand, if there is a shortage of fat donor sites, selection is difficult.

Tip For the combined method, it is a strategy to revisit a hospital with extensive experience in fat grafting at K-Dia once recovery is complete (3-6 months) after the first implant surgery. There are separate places that excel only in the second procedure.

Selection Criteria by Case: 3 Variables: Body Type, Age, and Lifestyle

For those in their 20s with a lean body type (BMI 18 or lower), submuscular insertion is safe due to thin tissue, but one must endure a recovery period (4 weeks) and pain. Fat grafting is not recommended due to a shortage of donor sites.

For those in their 30s with a standard body type (BMI 20-23), there is a wide range of options. For a 1-2 cup increase, consider submuscular implants; if naturalness is the priority, consider 2-3 sessions of fat grafting; and if both large volume and naturalness are desired, consider a combination method. For women over 40, skin sagging and breast checkup frequency must be considered together. If sagging is severe with implants alone, a breast lift is necessary; with fat grafting, the mammography frequency (every 2 years) must be considered due to the risk of calcification. For professions that heavily utilize chest muscles, such as athletes or Pilates instructors, there is a possibility of implant displacement when inserted submuscularly. In this case, submuscular or dual-plane implants are more stable. If you are planning to have children, while implants have minimal impact on breastfeeding (less than 5% duct damage), fat grafting is recommended after childbirth as calcification within the mammary gland tissue can cause discomfort during breastfeeding.

Age/Body Type	1st Priority Recommendation	2nd Priority Alternative	Precautions
20s Slim Body Type	Submuscular Implant	Dual-plane	4-Week Recovery Required
30s Standard Body Type	Supramuscular or Fat Grafting	Combination Method	Depending on Desired Size
40s and Over	Supramuscular + Lift	Implants + Fat	Breast Screening First
Working in a Activated State	Supramuscular	Fat Grafting	Avoid Submuscular

Recovery, Cost, and Long-term Maintenance: Reality Check for Each Method

For implants placed above the muscle, return to daily life is possible after 2 weeks, while for implants placed below the muscle, 4 weeks are required. Fat grafting takes 1 week, but if repeated 2-3 times, the total recovery period is 3-6 months. The combined method is longer, equivalent to the sum of two recovery periods. As of 2024 in Seoul, the cost ranges from 6 to 12 million KRW for implants alone, 4 to 8 million KRW for a single fat grafting session (totaling 12 to 24 million KRW for 2 to 3 repetitions), and 15 to 25 million KRW for the combined method. The reoperation rate is 15% for implants within 10 years and 60% for fat grafting requiring re-procedure. The manufacturer recommends an implant replacement cycle of 10 to 15 years, but there are many cases where they are maintained for over 20 years. However, replacement surgery is required in the event of capsular contracture or rupture, and the cost is approximately 70% of the initial surgery cost. While the grafted fat is semi-permanent once it takes root, breast volume changes with weight fluctuations. It is common for breasts to shrink by 10-15% when losing more than 5kg. Long-term satisfaction varies greatly from person to person, but a 2019 follow-up study by Plastic and Reconstructive Surgery showed that after 5 years, satisfaction was 78% for implants, 71% for fat grafting, and 84% for a combination. While the combination method shows higher satisfaction, the cost and recovery burden must be taken into account. Key Point: While implants may appear cheaper in terms of cost alone, they are similar in price or more expensive when combined with 2-3 fat grafting sessions. Compare by summing up total cost, recovery period, and the possibility of re-procedure.

• Supramuscular implant recovery 2 weeks, submuscular 4 weeks
• Fat graft recovery 1 week per session, 3-6 months total after 2-3 repetitions
• Cost: Implants 6-12 million KRW, Fat grafting total 12-24 million KRW, Combined 15-25 million KRW
• Satisfaction after 5 years: Implants 78%, Fat grafting 71%, Combined 84%

Common misconceptions

Misconception Fat grafting is always better than implants because it looks natural

Truth Fat grafting is limited to an injection volume of 50-150cc per session, making it impossible to enlarge by more than 1-2 cups. If repeated 2-3 times, the total cost is higher than that of implants, and the survival rate is difficult to predict at 60-80%. If you want a large volume, implants are more efficient.

Misconception Implants must be replaced every 10 years without exception

Truth While the manufacturer's recommended replacement cycle is 10-15 years, there are many cases where implants are maintained for over 20 years if there are no issues such as rupture or capsular contracture. According to FDA 2019 data, the replacement rate within 10 years was only 15%. You only need to check for any abnormalities through regular checkups.

Must-check items before breast augmentation

• Whether tissue thickness, chest width, and nipple position have been precisely measured using 3D CT or ultrasound
• For those 40 years and older, mammography must be completed before the procedure — interpretation is difficult for 6 months after fat grafting
• Avoid excessive injection (over 200cc) in a single fat graft — risk of calcification and necrosis increases sharply
• Absolutely prohibit exercises using chest muscles (push-ups, bench press) for 4 weeks after submuscular implant insertion
• For the combined method, fat grafting is only possible at least 3 months after implant insertion — risk of capsular contracture if performed simultaneously

Frequently Asked Questions

Is there really a big difference in tactile sensation between implants and fat grafting?

Submuscular implants feel close to a natural texture, but if the tissue is thin, the outline of the implant may be palpable underneath. Fat grafting uses entirely autologous tissue, so the tactile sensation is the most natural, but with a survival rate of 60-80%, it is difficult to predict volume. The combined method offers the highest satisfaction in tactile sensation, but it entails significant financial and time burdens.

How much is the total cost if fat grafting is repeated 2-3 times?

The cost is 4-8 million KRW per session, totaling 12-24 million KRW for 2-3 sessions. Although it is more expensive than implants alone (6-12 million KRW), it is an option if you desire natural results without foreign substances. However, since engraftment rates vary individually, there are cases where more than three procedures are required, so you need to allow for a sufficient budget. What should be done if capsular contracture occurs? Capsular contracture is a phenomenon where an excessive fibrous membrane forms around the implant, causing it to harden. The incidence rate is 12% for supramuscular implants and 8% for submuscular implants. Mild cases (Baker stages 1-2) are monitored, but severe cases (stages 3-4) require capsule removal and implant replacement surgery. To prevent this, breast massage and regular check-ups for three months after surgery are important. I exercise a lot; which method is safe? Athletes or Pilates instructors who use their chest muscles extensively face a risk of implant displacement when inserting submuscular implants. Supramuscular or dual-plane implants are more stable, and fat grafting is also an alternative. You must stop chest muscle exercises (push-ups and bench presses) for at least 6 weeks after surgery. Does it affect breastfeeding after childbirth? With implants, the rate of milk duct damage is less than 5%, so breastfeeding is generally possible; however, the risk of duct damage is slightly higher with an areolar incision. With fat grafting, calcification within the mammary gland tissue can cause discomfort during breastfeeding, so if you plan to have children, we recommend the procedure after delivery. Neither method can be performed while breastfeeding. What are the side effects or complications after breast augmentation? With implants, capsular contracture (8-12%), implant rupture (5% within 10 years), infection (less than 1%), and asymmetry (5-10%) are reported. With fat grafting, calcification (5-15%), cyst formation (3-8%), and asymmetry due to engraftment failure are reported. Combination methods carry risks from both approaches, but they can be managed if performed in stages. Before the procedure, be sure to consult with a specialist regarding your tissue condition, lifestyle patterns, and family history.
