A remarkable difference you can see and feel.

It takes a skilled plastic surgeon to create the perfect look. But only your implant can create the right feel.

At Sientra, we offer both round and shaped (teardrop) implant options. Each utilizes a proprietary gel fill technology, High-Strength Cohesive (HSC) Silicone Gel, with a formulation unique to each implant shape.

OPUS® Breast Implants with High-Strength Cohesive Silicone Gel

Available only to Board-Certified and Board-Eligible Plastic Surgeons


HSC Round

The round implant with the strongest cohesive gel on the market, yet soft to the touch.

  • The only round implant made with HSC and HSC+ Silicone Gel for the desired look and feel
  • Offers a fuller, more dramatic appearance in the upper portion of the breast
  • Available in both a smooth and a textured surface
  • Covered by Sientra Platinum20™, the industry’s best warranty program


HSC+ Shaped

The first FDA-approved shaped breast implant. Not too hard, not too soft.

  • Our proprietary HSC+ Silicone Gel allows the implant to hold its shape without feeling too firm
  • Designed to mimic the natural look and feel of a breast
  • Textured surface designed to maintain the position of the implant in your body
  • Covered by Sientra Platinum20™, the industry’s best warranty program

Round implants are the right choice for a fuller appearance and more dramatic cleavage. Our shaped implants, with a more cohesive gel fill, are designed to create a more contoured, natural silhouette. Each style combines our exclusive HSC Silicone Gel interior with a durable outer shell to create a soft, natural-like feel without sacrificing the integrity of the implant.

One shape does not fit all. That’s why both round and shaped implants are available in different shapes and sizes so that you and your board-certified plastic surgeon can create the look that’s right for you.

We believe in Sientra's product.

The cohesivity of the gel, maintenance of the projection, and the results we saw from early independent tests done by other plastic surgeons, confirmed for us that Sientra is the innovator in the field.
