Breast implant rippling happens when the implant shell folds or wrinkles in a way that becomes visible or palpable through the skin. It affects up to 20% of patients, and while it’s not dangerous, it can be a significant cosmetic concern. The causes come down to a combination of implant characteristics, surgical placement, and how much natural tissue you have covering the implant.
How Rippling Forms
Every breast implant has a flexible outer shell, and that shell can develop small folds, similar to wrinkles in a partially filled water balloon. Whether those folds stay hidden or show through to the surface depends on what’s between the implant and your skin. When there’s enough breast tissue, fat, and muscle layered over the implant, those folds get cushioned and stay invisible. When that padding is thin, the folds press against the skin’s surface and create visible ridges or waves.
Rippling tends to be most noticeable along the outer and lower edges of the breast, where tissue coverage is naturally thinnest. In some cases you can see the ripples; in others, you can only feel them when pressing on the breast. A prospective study published in Plastic and Reconstructive Surgery Global Open found that 18% of women reported visible rippling while 32% reported palpable rippling, meaning you’re more likely to feel it than see it.
Tissue Thickness Is the Biggest Factor
The single most important variable is how much natural tissue sits between the implant and your skin. Women with thin breast tissue, low body fat, or a low BMI are consistently at higher risk. Research on prepectoral breast reconstruction has found that rippling is inversely associated with breast flap thickness: the thinner the tissue, the more likely ripples become visible. Poor subcutaneous fat before surgery is one of the strongest predictors.
This is why rippling is more common in very lean women and in patients who’ve had mastectomies, where most of the breast tissue has been removed. It also explains why rippling can develop over time. As you age, skin thins and breast tissue changes, so implants that looked smooth for years can eventually start showing folds.
Saline vs. Silicone: Less Difference Than You’d Think
There’s a widespread belief that saline implants ripple far more than silicone, and surgeons often recommend silicone for patients with thin tissue. The logic makes sense: silicone gel holds its shape better than liquid saline, so it should fold less. But the clinical data is more nuanced than the conventional wisdom suggests.
In the same prospective study, ultrasound scans detected ripples in 24% of women with saline implants and 27% of women with silicone gel implants, a difference that was not statistically significant. Visible rippling rates were 22% for saline and 12% for silicone, but this difference also didn’t reach significance. The takeaway isn’t that implant type doesn’t matter at all, but that tissue coverage plays a larger role than filler material in determining whether rippling becomes a problem.
Highly cohesive silicone implants (often called “gummy bear” implants) were expected to reduce rippling further because their firmer gel resists folding. Current research, however, has not demonstrated a clear advantage in rippling rates. The factors that matter most remain tissue thickness, implant size relative to your frame, and placement.
Placement Above vs. Below the Muscle
Where the implant sits in relation to the chest muscle makes a meaningful difference, at least in certain areas. There are two basic options: above the muscle (subglandular) and below the muscle (submuscular or subpectoral).
Submuscular placement adds an extra layer of tissue over the upper portion of the implant, which helps conceal rippling in the upper breast. Long-term observations have confirmed that upper pole rippling is less common with submuscular placement compared to subglandular. However, the muscle doesn’t extend to cover the lower and outer edges of the implant, so rippling in those areas can still occur regardless of placement.
Submuscular placement comes with its own trade-offs: higher rates of implant displacement and visible distortion when the chest muscles contract. Prepectoral (above the muscle) placement avoids those issues but tends to produce more visible rippling, which is why fat grafting is often paired with it.
Implant Size and Underfilling
An implant that’s too wide for your chest creates edges that extend beyond where your natural tissue can cover them, making rippling more visible along the sides. Surgeons generally aim for an implant diameter that matches or is slightly narrower than the breast width, especially in patients with limited natural tissue.
With saline implants, fill volume also plays a role. Saline implants are filled during surgery, and the surgeon chooses a volume within the manufacturer’s recommended range. Underfilling leaves extra room inside the shell, creating more slack for the shell to fold. This is one area where saline and silicone genuinely differ, since silicone implants come pre-filled and can’t be underfilled. Smaller implant sizes have also been associated with rippling in reconstruction patients, likely because smaller implants leave less internal pressure pushing the shell smooth.
How Rippling Is Corrected
If rippling develops, several revision strategies can reduce or eliminate it. The right approach depends on what’s causing the problem and how severe it is.
Fat Grafting
Fat transfer is the most common correction, particularly for patients whose rippling stems from thin tissue coverage. Fat is harvested from the flanks, abdomen, or thighs using liposuction, then injected into the subcutaneous layer over the implant to add cushioning. The fat is carefully placed above the implant, creating a thicker buffer between the shell and your skin.
The limitation is that not all of the transferred fat survives. Volume retention at about five months is roughly 25% to 50%, meaning some of the initial improvement fades as the body reabsorbs a portion of the grafted fat. For most patients, a single round of fat grafting at the time of implant exchange is enough. About 15% to 18% of patients need a second session.
Tissue Matrix Overlays
For more pronounced rippling, especially in the upper breast or along the inner edge, surgeons can place a sheet of acellular dermal matrix (a processed tissue graft) between the implant and the skin. This acts as an internal layer that thickens the tissue and camouflages the implant edges. The material is sutured into place over the areas of thinning, providing structural support that fat alone may not achieve.
Changing Placement or Implant Type
Sometimes the best fix involves switching from above-the-muscle to below-the-muscle placement, swapping saline implants for silicone, or choosing a different implant size that better matches your frame. These are more involved revisions, but they address the root cause rather than adding coverage over the existing setup.
Who Is Most at Risk
Several factors increase your likelihood of developing rippling, and many of them overlap:
- Low body weight or BMI, which correlates with less subcutaneous fat over the implant
- Naturally thin breast tissue, whether genetic or the result of mastectomy
- Subglandular placement, which provides no muscle coverage
- Saline implants, particularly if underfilled
- Oversized implants that extend beyond the natural breast footprint
- Aging and weight loss after surgery, which can thin the tissue over time
Rippling isn’t always preventable, but understanding these risk factors before surgery gives you the best chance of minimizing it. For women with thin tissue, the combination of silicone implants, submuscular placement, and appropriately conservative sizing offers the lowest risk profile. When rippling does develop, it’s one of the more reliably correctable implant complications.
