Silicone vs. Saline Breast Implants


When considering breast augmentation, one of the most crucial decisions is the type of implant to choose. Knowing the best size and shape of the implant is one thing, but how about the best type?

In the UK, the two primary options for type of implant are silicone and saline breast implants. Each type has its unique properties, advantages, and potential drawbacks. Understanding these differences can help you make an informed decision that aligns with your aesthetic goals and lifestyle.

What are Silicone Breast Implants?

Silicone breast implants are filled with a silicone gel that closely mimics the feel of natural breast tissue. They are the most common choice of implants in the UK

Pros of Silicone Breast Implants

  • Natural Feel and Appearance – Silicone implants are known for their ability to provide a more natural feel and look in comparison to saline implants. The gel consistency mimics the softness of natural breast tissue.
  • Lower Risk of Rippling – The thicker gel in silicone implants tends to be less prone to rippling. This is where the edges of the breast implant create visible wrinkles under the skin.
  • Long-lasting – Silicone implants generally have a longer lifespan than saline implants, often lasting 10-20 years before requiring removal or replacement.

Cons of Silicone Breast Implants

  • Cost – Silicone implants are typically more expensive than saline implants due to the more complex manufacturing process.
  • Silent Rupture – If a silicone implant ruptures, the gel may stay within the implant shell or leak into the breast implant pocket. This can be difficult to detect without an MRI or ultrasound.
  • Surgical Considerations – It has been noted that silicone implants require a slightly larger incision for placement however at The Private Clinic, our surgeons are experts in implant placement and our breast implant incisions are often between 3-5cm.

What are Saline Breast Implants?

Saline breast implants are filled with a sterile saltwater solution. They are typically inserted empty into the breast. During the procedure, the sterile salt water is poured into the empty silicone outer shell.

Pros of Saline Breast Implants

  • Safety – If the implant was to rupture, the body can naturally absorb the saline solution, which poses no health risk.
  • Adjustable Size – During surgery, the implant can be filled to the desired volume, offering flexibility in achieving the precise size and symmetry to the breasts.
  • Smaller Incisions – Saline implants are inserted empty and filled once in place, allowing for smaller incisions.

Cons of Saline Breast Implants

  • Less Natural Feel – Saline implants tend to be firmer and are not known to feel as natural as silicone implants. They are also more prone to wrinkling and rippling.
  • Higher Risk of Complications – Studies have shown a slightly higher rate of complications, such as capsular contracture (scar tissue formation around the implant), with saline implants compared to silicone.
  • Potential for Deflation – Saline implants often deflate if they rupture which causes an instant and noticeable change in breast size and shape.

Which Implant type is best?

Choosing between silicone and saline breast implants will ultimately depend on your personal preferences, body type, and desired outcome.

It’s essential to have a thorough consultation with an experienced plastic surgeon who specialises in breast surgery to discuss your goals and concerns. Your surgeon will provide expert guidance on the most suitable implant type based on your individual anatomy and aesthetic aspirations.

At The Private Clinic, our surgeons tend to only use silicone implants. This is because they achieve a more natural look and feel to the breast which is what many patients want. They also have a great range of customisation from implant shape, size and profile along with the placement which can help to reduce the risk of rippling, wrinkling and folding.

We also want to reduce the risk of capsular contracture where possible and choosing silicone implants can do this.
