Smooth or textured implants — what is the actual difference?
The difference is the shell surface: smooth shells glide in the pocket, textured shells grip tissue — and textured surfaces have been linked to a rare lymphoma, shifting practice toward smooth.
Every implant question eventually reaches the shell. A smooth surface lets the implant move naturally within its pocket; a textured surface was designed to adhere to surrounding tissue, originally to hold shaped implants in position and to influence scar-capsule behavior.
What changed the balance
The FDA has associated a rare lymphoma of the immune system, BIA-ALCL, predominantly with textured-surface implants, and certain heavily textured models were withdrawn from the market in 2019. The condition is uncommon and treatable when caught, but the finding pushed many practices toward smooth round implants.
Texture still has defenders in specific anatomic situations, and regulations differ by country, so the choice is not automatic. What fits an individual chest — including how each option behaves long-term — deserves a walk-through with a board-certified specialist rather than a shorthand answer.
