Types of Breast Implants: Filling, Shape, Surface and Profile Compared

Breast implants are classified into four variables — filling material, shape, outer surface, and projection profile — and the right combination depends on your anatomy, tissue coverage, and personal goals.

At the most basic level, fillings include saline, silicone gel and highly cohesive silicone gel. Shapes are either round or teardrop. Shells come smooth or textured. Profiles range from low to high projection.

No single combination suits everyone; each variable involves trade-offs in feel and appearance that relate to look and feel, as well as cost and long-term monitoring.

This guide walks through each variable, explains the trade-offs in plain language, and ends with a set of questions you can take to a consultation.

Breast Implant Definition and Lifespan

A breast implant is a medical device placed under the breast tissue or chest muscle to increase breast size or restore volume lost after surgery or weight change. According to the FDA implant types overview, implants consist of a silicone outer shell filled with either sterile saline solution or silicone gel.

Cleveland Clinic notes implants are not considered lifetime devices. The FDA states that the longer you have breast implants, the greater the chance you may develop complications, some of which may require further surgery.

There is no fixed expiry date. Replacement is typically needed only if a complication arises — such as rupture, capsular contracture, or a change in position — or if you wish to change the size or type via breast implant exchange.

Candidacy Considerations for Breast Implants

Breast augmentation is an elective procedure, and candidacy depends on several health and lifestyle factors.

General considerations include:

• Good overall physical health, without conditions that could increase surgical risk
• In the United States, the FDA approval ages for augmentation are 18+ for saline implants and 22+ for silicone implants; other countries may differ.
• Emotional readiness and realistic expectations — implants can change breast size and shape, but cannot resolve deeper concerns about self-image
• Willingness to commit to long-term follow-up, including periodic imaging for silicone implants

People who are very physically active may wish to discuss how implant size could affect comfort during exercise. If you are considering additional procedures such as a breast lift with implants, mention this during your consultation so your surgeon can plan accordingly.

A board-certified plastic surgeon can assess your anatomy, discuss your goals and recommend the options that may work for you.

Breast Implant Surgery: Procedure Overview

Surgery time and anaesthesia type vary depending on the technique. Whether other procedures are done at the same time, most patients go home the same day.

Your surgeon will make an incision in one of three locations:

• Inframammary fold — the crease beneath the breast
• Periareolar border — around the edge of the areola
• Transaxillary — in the armpit

Each incision site has different trade-offs for scar visibility and surgical access. Your surgeon can explain which is most appropriate for your body.

The implant is then placed in one of two positions:

• Submuscular (under the pectoral muscle) — may offer a more natural look, particularly for people with less existing breast tissue, but recovery can take slightly longer.
• Subglandular (above the muscle, behind breast tissue) — typically involves a shorter recovery but may be more prone to visible implant edges in people with thin tissue.

Recovery Timeline After Breast Implant Surgery

Most patients return to light daily activities within 7 days, though full recovery typically takes 6 to 8 weeks.

• First few days: soreness, swelling and mild bruising are common; pain medication can help manage discomfort
• Week 1: light activities are generally manageable; avoid heavy lifting and intense exercise
• Weeks 2–4: most people can resume normal routines, though strenuous activity should still be limited
• Weeks 6–8: most light activities are comfortable; some surgeons advise avoiding high-impact exercise for up to 3 months

According to the ASPS (American Society of Plastic Surgeons), following all post-operative instructions is essential to reduce the risk of complications such as implant shifting, capsular contracture or infection.

Final results typically become apparent after 2 to 3 months as swelling resolves and implants settle into position.

Breast Implant Filling Types: Saline, Silicone and Cohesive Gel

The 3 approved filling materials — saline, silicone gel and highly cohesive silicone gel — differ in feel, rupture behaviour and cost.

Saline Breast Implants

Saline implants have a silicone shell filled with sterile salt water during surgery.

• If ruptured, the body absorbs the saline harmlessly, and the deflation is usually obvious straight away.
• The surgeon can make small volume adjustments during the procedure.
• May feel firmer and less natural than silicone, especially in people with minimal breast tissue
• Carry a higher risk of visible rippling.

Silicone Gel Breast Implants

Silicone breast implants come pre-filled with a soft silicone gel that closely mimics the feel of natural breast tissue.

• Less likely to ripple than saline
• If ruptured, the gel may stay contained within the scar capsule, so you may not notice any change — this is known as a silent rupture.
• The FDA recommends periodic ultrasound or MRI screening for silicone implants (see Monitoring and Follow-Up below)

Gummy Bear Breast Implants (Cohesive Gel)

Cohesive gel implants — sometimes called gummy bear implants — are filled with a thicker, more cross-linked silicone gel that holds its shape even if the outer shell is damaged.

• Strong shape retention and low risk of gel leaking into surrounding tissue
• Tend to feel firmer than standard silicone.
• Typically requires a slightly larger incision for placement.
• It may cost more than other filling types.

Saline vs Silicone vs Cohesive Gel: Summary

• Saline offers the easiest rupture detection and the lowest material cost, but may feel less natural.
• Silicone gel provides the closest match to natural tissue feel with a lower risk of rippling, but requires imaging to detect silent rupture.
• A cohesive gel provides the greatest shape stability and the lowest leakage risk. Still, it has a firmer feel and may require a larger incision.

Round vs Teardrop Breast Implants

Round implants are the more commonly chosen shape and tend to be less expensive; teardrop implants may suit people with very little existing breast tissue who want a subtle, natural contour.

Round Breast Implants

Round implants are symmetrical and provide fullness across the entire breast, particularly in the upper pole (the area above the nipple). Because they are the same shape in every direction, there is no concern that rotation will alter the breast’s appearance.

Teardrop (Anatomical) Breast Implants

Teardrop implants are designed to mimic the natural slope of the breast, with more volume towards the bottom and a gentler taper at the top.

The trade-off is that teardrop implants can rotate inside the pocket, which may distort the breast shape and require corrective surgery. For this reason, most teardrop implants are manufactured with a textured surface to help them stay in place. They also tend to cost more than round implants.

When choosing between round and teardrop breast implants, consider that round options tend to offer more upper-pole fullness. In contrast, teardrop shapes may produce a gentler slope that some people find more natural-looking.

Textured vs Smooth Breast Implants

Smooth implants are the most widely used type globally; textured implants reduce rotation risk but are associated with a small increased risk of a rare form of lymphoma.

Smooth Implants

Smooth implants have a polished outer shell and can move freely within the breast pocket. This movement is sometimes described as more natural.

Textured Implants

Textured implants have a roughened outer shell that grips the surrounding tissue. They were originally developed to help reduce capsular contracture (the tightening of scar tissue around the implant). Textured surfaces are also used on most teardrop implants to minimise the risk of rotation.

However, certain textured implants have been associated with a rare cancer of the immune system called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). This is not a cancer of the breast tissue itself — it develops in the scar capsule around the implant.

BIA-ALCL Safety and Symptoms

According to the American Cancer Society update, the FDA reporting up to 30 June 2023 listed 1,264 cases of BIA-ALCL worldwide and 63 deaths. The estimated lifetime risk with textured implants ranges from roughly 1 in 3,817 to 1 in 30,000, based on published literature. To date, no confirmed case has involved a patient with only smooth implants.

In 2019, the FDA requested a recall of Allergan BIOCELL textured breast implants after data showed a significantly higher risk compared with other textured products. According to the American Cancer Society, the FDA reporting up to 30 June 2023 listed 1,264 cases of BIA-ALCL worldwide and 63 deaths. The overall risk remains low, but awareness is important.

Symptoms to watch for:

• Painless swelling of the breast that develops years after implant placement, on average, around 8 to 10 years after surgery, according to the ASPS, though it can occur anywhere from 2 to 28 years after surgery.
• A lump in the breast or armpit
• Breast asymmetry, pain, skin rash over the breast, or hardening of the breast

If you notice any new swelling, a lump, pain, or a change in the size or shape of a breast — particularly one that develops well after the initial healing period — contact your surgeon or doctor promptly to discuss breast implant removal options if advised. Early detection and complete surgical removal of the implant and surrounding capsule can often be curative.

The FDA does not recommend removing textured implants in people without symptoms. However, if you have textured implants, it’s important to stay aware of potential changes.

High Profile vs Moderate Profile Implants

Implant profile refers to how far the implant projects outward from the chest wall, and 2 implants with the same cc volume can look quite different depending on their profile.

• Low profile: wider base and less forward projection; may suit people with a broader chest who want a subtle, spread-out appearance.
• Moderate profile: a balance between base width and projection; the most commonly chosen profile, suitable across a range of body types
• High profile: narrower base and greater forward projection; can suit people with a narrower chest who want more noticeable projection, or those choosing a larger volume without an overly wide footprint.

Think of cc as the total volume of filling inside the implant, and profile as the shape of the container that holds it. Your surgeon will use chest measurements and tissue assessments to recommend the profile that best fits your frame.

Breast Implant Sizes: How to Choose

Implant size is measured in cubic centimetres (cc), not bra cup sizes, because cup sizes vary between brands and manufacturers.

Your surgeon will consider:

• Chest width and existing breast tissue
• Skin elasticity and overall body proportions
• Your lifestyle and activity level
• Your aesthetic goals and expectations

Implants that complement your frame tend to look more natural and carry a lower risk of complications such as rippling or tissue thinning. Starting with a more conservative size does not rule out future adjustments — revision surgery can increase or change implants if your goals evolve.

Bring reference photos to your consultation if they help, and ask your surgeon to explain how different cc volumes and profiles would look on your body.

Breast Implant Cost: U.S. Average and What It Includes

In the United States, the ASPS reports that the average cost of breast augmentation with implants is $4,875. However, actual prices vary widely by location, surgeon and implant type.

Factors that can affect the total cost:

• Geographic location — urban and coastal areas often have higher fees
• Surgeon’s experience and credentials
• Implant type — cohesive gel and teardrop implants tend to cost more
• Additional procedures performed at the same time, such as a breast lift

What published averages may not include:

• Pre-operative tests and consultations
• Post-operative garments and prescription medications
• Follow-up imaging, such as MRI screening for silicone implants
• The potential cost of future revision surgery

When comparing quotes, ask for an itemised breakdown so you can compare like-for-like. Breast augmentation is generally considered a cosmetic procedure. It is not covered by most insurance plans, except in cases of reconstruction following mastectomy or certain medical conditions.
