Almost every woman who consults for breast augmentation arrives having read something about implant types. Usually, what they've read is either too technical to be useful or oversimplified to the point of being misleading.
The actual decision comes down to a few well-defined factors. Once you understand what each implant type does and why, the choice for most women becomes fairly clear.
The Basic Taxonomy
There are two shell materials in use for breast implants globally: silicone gel shells and saline (sterile saltwater) shells. Within silicone, there are two major gel types: standard silicone gel and cohesive gel.
Cohesive gel implants — colloquially called "gummy bear" implants — use a cross-linked silicone gel that holds its shape even if the shell is cut. This is where the name comes from: like a gummy bear, they can be cut and the gel doesn't flow or migrate.
| Feature | Cohesive Gel (Gummy Bear) | Standard Silicone Gel | Saline |
|---|---|---|---|
| Feel | Natural, firm-soft | Natural, slightly softer | Firmer, can feel water-balloon-like |
| Shape retention | Excellent; holds teardrop or round form | Good | Lower; round only |
| Rupture behaviour | Gel stays in place (cohesive) | Gel may migrate slowly | Deflates visibly; saline absorbed safely |
| Rupture detection | MRI (silent rupture) | MRI (silent rupture) | Immediately visible deflation |
| Profile options | Low, moderate, high, ultra-high | Same | Primarily round, moderate/high |
| Most used in India? | Yes — standard of care | Yes — still in use | Less common |
Why Cohesive Gel Has Become the Standard
For Indian women specifically, cohesive gel implants have become the default recommendation at most qualified plastic surgery practices for two reasons.
First, the average Indian woman has a smaller breast base diameter than Caucasian or East Asian patients. Choosing a round saline implant in a smaller frame can look visibly spherical — the "done" look that nearly every patient says she does not want. Cohesive gel implants, particularly anatomical (teardrop) profiles, distribute volume more naturally in a narrower base width.
Second, the feel difference is meaningful in thinner patients with less existing breast tissue. When there is minimal natural tissue to cover the implant, the texture and firmness of saline becomes more perceptible. Cohesive gel mimics natural breast tissue better, particularly in the upper pole.
“The 'natural result' every patient asks for is mostly determined by implant placement, profile, and volume selection relative to the patient's frame — not just the implant type. But when two options are otherwise equal, cohesive gel consistently gives a better feel and shape outcome in Indian women with smaller base widths.”

The Rupture Conversation
Saline has one advantage that cohesive gel does not: rupture is immediately obvious. If a saline implant deflates, you see and feel it within hours. The saline is absorbed by the body harmlessly.
With cohesive gel, rupture is "silent" — the gel stays cohesive and in place, so you may not notice it has occurred. Detection requires MRI imaging. The current FDA guidance for silicone implants recommends MRI screening at 5 to 6 years post-implantation and every 2 to 3 years after that. In India, this is not yet a widely followed patient-education point, which means many women are not being told about the screening recommendation at the time of surgery.
Round vs Anatomical (Teardrop): A Separate Decision
Both saline and cohesive gel implants come in round shapes. Only cohesive gel comes in anatomical (teardrop) shapes — because the gel must hold its form to maintain the teardrop profile.
Round implants provide more upper-pole fullness — cleavage volume. Anatomical implants provide more lower-pole fullness with a subtle, natural slope. For women who have had children and want volume restoration without a prominently augmented upper pole, anatomical cohesive gel is typically the better match.
What Actually Determines the Look
Patients often arrive having decided on a specific implant type before they have been assessed. The honest answer is that implant type matters — but placement (sub-glandular vs sub-muscular vs dual-plane), volume selection relative to breast base diameter, and the surgeon's understanding of the patient's proportional goals determine the final result more than any single implant variable.
The implant type is the starting point of the conversation, not the ending point.
