A 300cc implant refers to a breast implant that has a volume of 300 cubic centimetres (cc), which is the unit used to measure the size of breast implants. The “cc” value of an implant indicates how much fluid or silicone gel the implant contains. In general, the higher the number, the larger the implant. The 300cc size is considered a moderate volume, often chosen by women looking for a noticeable but natural enhancement to their breasts.

There are two main types of breast implants: saline and silicone. While the material inside can vary, the size, in terms of volume, remains consistent. Silicone implants are often favoured due to their natural feel and shape, but some patients may choose saline implants for personal preference or specific medical reasons. The use of saline implants in the UK is very rare these days. In our practice, 300cc boob implants are one of the most commonly used sizes for breast augmentation or boob jobs.

What Does a 300cc Breast Implant Weigh?

The weight of a 300cc implant is determined by its volume and the density of the filling material. In general:

• Saline implants: 1 cc of saline weighs 1 gram. Thus, a 300cc saline implant would weigh approximately 300 grams, or around 0.66 pounds.
• Silicone implants: Silicone gel is denser than saline, so a 300cc silicone implant would weigh slightly more, typically around 315 to 330 grams (0.7 pounds).

This weight is distributed evenly across the breast area, but it is important to note that the additional weight can sometimes influence posture, back support, and even shoulder tension, especially in larger sizes.

Is the 300cc Breast Implant Big?

Whether a 300cc implant is considered “big” depends on several factors, including your starting breast size, body frame, and overall build. In the context of breast augmentation, a 300cc implant is typically classified as medium-sized.

For women with a smaller frame or petite build, 300cc can provide a noticeable increase in volume and may appear quite large. For women with a broader chest or a taller build, the same implant may appear more moderate. During your consultation we will measure your breast dimensions and these will form the basis of the choice of implants.

What Cup Size is a 300cc Implant?

Cup size after augmentation is a frequently asked question, but it is not straightforward. Implant sizes do not translate directly to cup sizes due to variations in breast shape, tissue distribution, chest width, and bra manufacturers. However, as a general guideline:

• A 300cc implant usually adds about 2 cup sizes to a woman’s natural breast size. For example, if you start as a small B cup, a 300cc implant could increase your breast size to a full C or even a small D cup.

To get an accurate estimation we may use imaging software, 3D simulations, or sizers during your consultation to help visualise the expected results. Mr Nassab will usually show you the implants during your appointment and you will have a chance to try these on. When you try the breast implants in a sports bra, it often gives you a better idea of how they may appear.

What Will a 300cc Breast Implant Look Like?

The appearance of a 300cc breast implant varies depending on placement (submuscular vs. subglandular), projection (moderate, moderate Xtra, high or high Xtra), and the shape of the implant (round vs. anatomical/teardrop). Factors like skin elasticity, existing breast tissue, and overall body shape play a major role in the final look.

• On a smaller frame: A 300cc implant tends to create a fuller and more projected look.
• On a larger frame: It may result in a subtle enhancement that complements the patient’s natural proportions.

To give you an idea, if you have a small to medium build, a 300cc implant can often create a fuller, lifted appearance, making the breasts look more rounded and voluminous without appearing overly augmented.

What is it Like Before and After a 300cc Boob Job?

Before and after a 300cc boob job, many women notice a significant difference not only in the size but also in the shape and firmness of their breasts. Here’s a breakdown of what to expect:

• Before the procedure, it’s crucial to have a thorough consultation to discuss your goals, take measurements, and review your options. Imaging and sizing systems may be used to give you an idea of the final results.
• During recovery, swelling and bruising are normal. The breasts may initially appear high and firm, but they will gradually soften and settle into a more natural position over the next few months.
• After recovery, most women find that their new breast size boosts confidence and enhances their overall figure. Many patients feel that their clothes fit better and enjoy the increased options in styles.

The long-term satisfaction is generally high for women who chose implants based on their body proportions and desired outcomes.

We have included some before and after photographs of patients that have had 300c breast implants and you will see there are very different from one another.

This patient underwent breast augmentation using a 300cc tear drop implant which had a medium height and high projection. This was placed under the muscle and we can see it provides a natural look enhancement.

How Can I See What a 300cc Boob Implant Will Look Like at Home?

If you’re curious about how a 300cc implant might look on your body, there are a few techniques you can try at home:

Rice Test or Water Test:

• The rice test involves filling a stocking or pantyhose with 300 grams of rice (1 cc = 1 gram of rice). Place this in your bra to simulate the look and feel of a 300cc implant.
• Alternatively, you can use a plastic bag filled with 300cc (ml) of water. Place this in a supportive bra to see how it adds volume.

Visual Aids:

• Take photos of yourself in a well-fitting bra from the front, side, and at a 45-degree angle. Compare these to images of women with 300cc implants who have similar body shapes to see if the proportion matches your goals.

Digital Imaging:

• There are several apps and online simulators where you can upload a photo of yourself and adjust the breast size to see what a 300cc implant might look like.

Consultation Sizers:

• The most accurate way to see what a 300cc implant will look like is to use sizers provided by your surgeon. These are physical models placed inside a bra to give you a feel for the weight, volume, and appearance of various implant sizes.

Choosing the Right Implant Size

Choosing the correct implant size is a highly personal decision that should be guided by your aesthetic preferences, lifestyle, and anatomical factors. While a 300cc implant may be ideal for some, it may not be suitable for others. Consider the following when choosing your implant size:

• Your natural breast tissue and starting cup size: Women with less natural tissue may find that even a smaller implant appears larger.
• Body proportions and symmetry: Implants should be selected based on your chest width and overall body balance to ensure a harmonious look.
• Lifestyle considerations: Consider how the added volume may impact activities like sports or other physical pursuits.
• Your long-term goals: Are you looking for a subtle enhancement, or do you prefer a more pronounced change?

Conclusion

A 300cc implant can be an excellent choice for women seeking a moderate enhancement that balances noticeable volume without looking overly augmented. However, the right size will always depend on individual factors, including your natural breast size, body shape, and aesthetic goals. During your consultation, we will discuss your specific aims and desired looks and try to advise you on what the right size implant may be for you.
