If you’ve ever considered breast augmentation, you’ll be met with a variety of options: implant type, shape, and surface texture. This guide walks through the differences between saline and silicone, round and shaped, and textured and smooth implants, to help you make an informed decision that fits your goals.

Saline vs. Silicone: The Core Choice

Every breast implant has a silicone outer shell. The difference is what’s inside: sterile saline (salt water at the same concentration as your body fluids) or cohesive silicone gel.

Saline Implants

Saline implants are filled with sterile saline after being placed in the breast pocket. Because they’re filled once inside, they can go through smaller incisions, potentially meaning smaller scars. If a saline implant ruptures, the body simply absorbs the saline with no health risk. The trade-off is that some people find saline doesn’t feel quite as natural as silicone.

Silicone Implants

Silicone implants are pre-filled with a cohesive gel that closely mimics natural breast tissue, so they’re often favored for a more realistic feel and appearance, with a lower tendency to ripple. They’re a popular choice for women with thinner tissue. A silent rupture may need ultrasound or MRI to detect, but modern implants are designed to minimize the risks of leakage.

Round vs. Shaped: Defining Your Silhouette

Round Implants

Round implants are symmetrical, giving balanced fullness to the upper and lower breast and often more cleavage. They’re popular for a fuller look. They can theoretically rotate, but this rarely matters because they’re symmetrical.

Shaped (Anatomical) Implants

Shaped, or teardrop, implants are fuller at the bottom and taper toward the top to mimic the natural slope of the breast — ideal for a subtle, natural enhancement. Because they’re not symmetrical, correct placement and orientation are important to avoid distortion.

It’s worth noting that some textured shaped implants have been associated with a small risk of rare capsule-related cancers (BIA-ALCL and BIA-SCC). You can read more in our post on BIA-ALCL and squamous cell carcinoma.

Textured vs. Smooth: Surface Matters

Textured Implants

Textured implants have a slightly rough surface to promote tissue adherence and reduce movement. This can help with certain complications, but textured devices have been linked to higher rates of implant-associated malignancy, which is why smooth implants are now the norm in most practices.

Smooth Implants

Smooth implants move more naturally within the pocket for a softer feel. The rate of capsular contracture may be slightly higher in some settings, but with modern technique the difference is small — and many women prefer the softer texture.

Your Journey, Your Choice

Every body and every preference is unique. The best way to choose between saline or silicone, round or shaped, textured or smooth is a consultation with a board-certified plastic surgeon who can match the implant to your anatomy and goals. Schedule a consultation to talk through your options.
