Yes, smooth implants are superior to textured, for one reason and one reason alone: they are not going to give you that rare lymphoma. It comes down to microns. Smooth is 0 to 2, Motiva SmoothSilk is 4 and behaves the same, and macro-textured is 40 to 90. There has never been a documented case of primary ALCL in a smooth or Motiva surface.
I'm going to do something I almost never do: answer a question definitively. I usually live in nuance, but on this one I'll plant my flag.
Yes, smooth implants are superior to textured implants, for one reason and one reason alone: they are not going to give you that rare lymphoma. Full stop.
Let me explain exactly what I mean, where Motiva fits in, and why the micron numbers are the whole story.
The lymphoma I'm talking about is BIA-ALCL (breast implant–associated anaplastic large cell lymphoma). It's rare, but it's real, and the single biggest thing we know about it is that it has been driven by surface texture. The more aggressively textured the implant surface, the higher the signal.
That's why, on the specific question of "smooth vs. textured," I can be unusually black-and-white: choosing a smooth surface takes that rare lymphoma risk off the table in a way textured surfaces don't. For the full picture of the rare cancers associated with implants, including BIA-ALCL and BIA-SCC, I've broken those down separately, but for this comparison, ALCL is the deciding factor.
Here's the part most people miss. "Textured" isn't one thing, it's a spectrum, and the depth of the texture in microns is what actually matters:
And this is the key point: I include Motiva SmoothSilk in the "smooth" category. A 4-micron surface and a 0-to-2-micron surface behave the same way. They are worlds apart from the 40-to-90-micron macro-textured implants that drove the ALCL signal in the first place. I've made this exact point before, that Motiva's SilkSurface is not the same as a macro-textured implant, and the micron math is why.
There has never been a documented case of primary ALCL in either a true smooth implant (0-2 micron) or in the Motiva 4-micron surface.
That's a significant fact, and it's why I group them together.
A lot of the BII community online pushes back on Motiva by saying something like, "That implant's only been on the market for a year, we don't know enough yet."
That's simply not accurate. Motiva has been used around the world for over 15 years. And smooth implants more broadly have been around for many, many decades. So the idea that we're working with brand-new, untested technology with no track record is just wrong. We have a long real-world history with both of these surfaces.
I always want to be straight with you, so here's the honest qualifier: it is certainly always possible that we could see cases of primary ALCL in either smooth or Motiva implants in the future. I'm not going to promise you something the data can't.
But as it stands today, in 2026, there have been no documented primary ALCL cases in true smooth implants or in the Motiva 4-micron surface. I'll always update my position if the evidence changes, that's what being evidence-based actually means, but I'm telling you where the data sits right now.
Given all of that, my position is straightforward:
The macro-textured surfaces are the ones tied to the ALCL signal, so for that one reason, I consider smooth implants the superior choice. If you're weighing your specific Motiva options, that's a great conversation to have at a consultation, but on the smooth-vs-macro-textured safety question, I'm comfortable being definitive.
Smooth implants are superior to textured implants for one reason: BIA-ALCL. That rare lymphoma has been driven by aggressive surface texture, and choosing a smooth surface takes it off the table.
I don't use or recommend macro-textured implants, and on this particular question, I'm happy to be as definitive as I ever get. Don't let online fear-mongering talk you out of an implant with a long, well-documented safety record.
