Gangnam Mentor Implants: Boost vs. Xtra vs. Smooth – A Comparative Analysis

Hello. I'm Dr. Kim Joo-won, chief director of Melon Plastic Surgery, your breast specialist with solutions for all breast concerns.
Today, I'd like to talk about breast implants, specifically Mentor implants.
Mentor has been a globally beloved brand for a long time, offering a diverse lineup of implants. From Mentor Smooth to Xtra and Boost, they have implants with different textures and characteristics.
Because Xtra and Boost are from the same brand, people sometimes mistakenly think they are the same. However, each implant possesses unique characteristics.
‘Smooth is softer, is that true?’‘Boost makes the upper chest firm, is that a fact?’
Now, let's examine each implant one by one. If you've been wondering which Mentor implant to choose, please refer to this article.
Mentor Implants | Mentor Boost, the top-tier in the Mentor lineup

Mentor is an American brand widely used in Korea.
Boasting a long tradition, it has abundant clinical data and stable surgical outcomes. Mentor implants are categorized into Mentor Smooth, Mentor Xtra, and Mentor Boost, depending on their surface texture and shape. Mentor Boost is the most recently introduced implant, belonging to Mentor's higher-grade line.
It boasts excellent fill rates up to the upper part of the implant, providing an overall firm and full volume. Perhaps due to this characteristic, it gives a more voluminous appearance compared to other implants of the same height. Many people who want to emphasize volume choose it.
Thus, Mentor Boost's advantage is its ability to enhance fullness through the implant itself. Its high safety, being a product from Mentor, the brand with the longest tradition among implant brands, is also one of the reasons for its popularity. Implants are fundamentally inserted under the skin. Therefore, the tactile sensation of the breast after surgery is heavily influenced by the skin.
This is one of the main reasons why we carefully examine skin type when checking skin conditions. The appropriate implant and the resulting feel can vary depending on whether the skin is thin or thick, soft or firm. Breast augmentation is a surgery that requires careful consideration and a three-dimensional understanding of many physical conditions.
It's best to consider all conditions, including not only skin thickness but also the shape and size of the rib cage, the breast pocket, and to refer to the medical team's opinion before choosing an implant that can naturally bring out the beauty of your breasts. As I always say, please remember that the best implant is not the most expensive or famous one, but rather one that suits your body type and beautifully balances with your body.
Mentor Implants | Mentor Xtra and Mentor Smooth

Mentor Xtra and Mentor Smooth are long-loved flagship implants of the Mentor brand. Mentor Xtra is Mentor's premium line, offering a texture that is both firm and soft, and an implant with strong shape retention.
It can be an appropriate choice if you want to maintain a consistent and stable volume. Typically, surgery is performed with micro-textured surface implants that have fine bumps, which helps with tissue adhesion. However, for those who expected the soft touch associated with Mentor, it might feel a bit firm.
Mentor Smooth is Mentor's standard line, characterized by a smooth surface. Its very soft texture played a significant role in establishing the perception that ‘Mentor is all about touch’. If a soft touch is your top priority, it might be suitable.
There are also points to be aware of. Being soft also means that the fill rate is relatively lower. This can cause wrinkles on the implant surface, which is something to consider if your skin is thin.
This phenomenon is commonly called rippling. This is because if the skin envelops the implant, wrinkles can show through the skin. It's also good to note that because it's smoother than textured types with bumps, its retention might be relatively lower.
In the breast augmentation process, choosing an implant is important, but taking ample time to thoroughly examine physical conditions such as skin type, rib cage, breast pocket, spine and breast shape, and desired appearance is crucial. Your ability to choose an implant will become clearer when you communicate and discuss sufficiently with the medical team.
Mentor Implants | What's important when considering breast augmentation?

‘The Boost shape is prettier, but will it suit me well?’‘Is it okay to use Xtra for thin skin?’
You cannot create beautiful or soft breasts with implants alone.
If you want beautiful breasts, you must first consider your body's conditions. For example, if your skin is thin, an implant with a fuller fill rate might be more stable than one with a lower fill rate that feels softer.
Implant conditions such as height, shape, width, fill rate, surface, and size interact with your physical conditions, such as skin type and breast pocket size. This is why the results can differ even when surgery is performed with the same implant.
Some people may have soft, swaying breasts, while others may have relatively firm breasts. Therefore, when choosing an implant, the process of considering your physical conditions and desired breast appearance together must come first to achieve the most beautiful breasts. Implant selection should start with finding what suits you, rather than what seems pretty.
Mentor Implants | From pre-surgery to post-surgery – The Melon Breast Journey

What's more important than the type of implant? It's pre- and post-operative care. Especially, post-operative recovery care is a crucial process that cannot be overemphasized.
This is because the outcome depends on how this time after surgery is managed. How you spend this period can affect satisfaction with shape, volume, and how clothes fit.
Immediately after surgery, care involves wearing a compression bra, adjusting sleeping position, and restricting arm use. This is a period for recovering the newly operated breasts and stabilizing the implant's position, so paying more attention than ever is beneficial for recovery. Afterward, precautions and care vary by period, which the medical team directly assesses based on progress.
At Melon Plastic Surgery, we systematically manage the recovery process from immediately after surgery up to about one year. This includes cooling packs to reduce breast heat, Capsulitis treatment to improve texture, lasers to help with swelling and tissue, and scar management. The implant's condition is also thoroughly checked through 1:1 progress checks between the medical team and patient, and regular ultrasound examinations.
Providing functional bras, scar ointment, and stretch mark cream for self-care is also to ensure continuous management. From implant selection, surgery, to post-operative recovery care – the entire breast augmentation process is a single surgical journey to create beautiful breasts.
At Melon Plastic Surgery, you will embark on this surgical journey with me, your primary physician, from pre-operative communication, including the process of selecting an implant and understanding your body, to post-operative recovery. If you have any concerns about your breasts, please don't hesitate to share them. We will be with you to find solutions for beautiful breasts.
Thank you.
