Kylie Jenner Finally Shared Her Breast Augmentation Details — Let's Break Them Down

After years of speculation, Kylie Jenner has actually told us the specifics of her breast augmentation — and as a plastic surgeon, I love when celebrities are transparent about what they've had done. It demystifies the process and helps regular people make informed decisions.

She shared four specific details, so let's translate what each one actually means in plastic surgery terms.

Per her post, the surgery was:

• 445cc implant
• Moderate profile
• Half under the muscle
• Silicone
• Done by Dr. Garth Fisher

Let's go through each of these.

445cc is an Allergan implant size. That specific number tells us she likely has Allergan implants (the sizes come in brand-specific increments, and 445 is an Allergan number).

Here's a useful frame of reference: on average, about 150cc equals one cup size. (I've written a full breakdown on how many cc are in a cup size — the real range is 100-250cc depending on body type.)

So a 445cc implant would bring someone up at least three full cup sizes. For a smaller-framed person like Kylie, that's a relatively large implant — it's a meaningful, noticeable augmentation, not a subtle one.

This is worth knowing for anyone using a celebrity's cc number as a reference point: 445cc on a petite frame is a big change, and the same number on a broader frame would look different.

Profile describes the relationship between how wide an implant is and how far it projects (sticks out):

• Low profile = wide and flat
• High profile = narrow and projects far forward
• Moderate profile = somewhere in the middle

We pick the profile based on your chest measurements — specifically the width of your chest and breast base. The implant should fit your chest properly.

So the process is:

1. You decide on the volume you want (via sizing)
2. The profile is then chosen based on your chest width to make that volume fit your frame correctly

I'll be transparent that this is just my observation looking at photos — I've never examined her. But for an implant of this relatively large size on her frame, I might have considered a higher profile rather than moderate. A higher profile would concentrate that volume more forward on a narrower base, which can look more proportionate on a petite chest with a large implant.

That said — Dr. Garth Fisher is a fantastic, highly regarded surgeon, and she looks great. Profile selection is a judgment call with legitimate room for different approaches, and the result speaks for itself. This is a case where reasonable surgeons could make different choices and both be right.

Her implants are silicone. This is a good opportunity to clear up a common misconception:

Here's the actual situation:

• The FDA trials that approved silicone implants in the US studied women 22 and older
• That's where the "22" number comes from
• So silicone implants are FDA-approved for cosmetic use at 22+
• But you can absolutely have silicone implants if you're under 22 — it's safe and fine to do
• It's just considered off-label under 22

So if you're under 22 and considering silicone implants, you can have them — just have an honest conversation with your surgeon about the off-label status. It's a labeling distinction, not a safety issue. (Saline implants are FDA-approved from age 18.)

"Half under the muscle" is the lay description of a dual plane augmentation.

In a dual plane placement:

• The upper portion of the implant sits under the pectoralis muscle
• The lower portion sits behind breast tissue (the muscle is released along its lower edge)
• This produces a natural lower-pole shape while keeping upper-pole muscle coverage

Dual plane is how the majority of us were doing augmentations at the time of her surgery. It's a great, well-established technique that has served patients well for many years.

I'll note that in recent years, I've moved toward subfascial placement for many patients, and that's the trend we're seeing in the field more broadly — along with a return to over-the-muscle approaches and newer tissue-preserving techniques like Preservé.

That doesn't mean dual plane is wrong — it's a proven, excellent technique. It just reflects how the field evolves over time. If Kylie had her surgery today, dual plane, subfascial, and over-the-muscle would all be reasonable options depending on her anatomy and goals.

I generally don't love guessing at celebrity work, and I have a lot of respect for celebrities who are open about what they've had done. When Kylie shares her exact implant size, profile, placement, and surgeon:

• It demystifies the augmentation process
• It gives regular patients a concrete reference point
• It normalizes having had work done rather than pretending it's all genetics
• It lets people have informed conversations with their own surgeons

This is the opposite of the J.Lo "olive oil and affirmations" approach — and I think it's genuinely more helpful to other women.

One thing I want every patient to take from this: don't walk into your consultation asking for "the Kylie."

• 445cc on Kylie's frame produces a specific look that won't translate to a different body
• The right profile for you depends on your chest width, not hers
• The right placement depends on your tissue, lifestyle, and goals
• Her result is specific to her anatomy and her surgeon's plan for her

Use it as interesting context, not a prescription. The right implant for you comes from sizing on your body with your surgeon — ideally with sizers and the rice trick to preview volumes at home first.

Kylie Jenner shared that her augmentation was a 445cc moderate-profile silicone implant, placed dual plane (half under the muscle), by Dr. Garth Fisher. Translating that:

• 445cc is a relatively large implant for her petite frame — roughly three cup sizes up
• Moderate profile fits the volume to chest width (I might personally have considered higher profile for that size on her frame, but Dr. Fisher is excellent and she looks great)
• Silicone under 22 is safe — it's off-label, not dangerous; the "22" comes from the FDA trial population
• Dual plane was the standard approach then; the field has since trended toward subfascial and over-the-muscle techniques

I appreciate the transparency — it helps everyone. Just remember that her specifics are specific to her. The right augmentation for you comes from sizing on your own body with a board-certified surgeon, not from copying a celebrity's numbers.
