collagen induction therapy is really just the clinical name for what microneedling does, theyre describing the same underlying process rather than two separate treatments. the term collagen induction therapy tends to get used more in professional or medical contexts to emphasize the mechanism behind the treatment, which is literally inducing your skin to produce more collagen through those controlled micro injuries. microneedling is more the common everyday term people use when talking about the actual device and procedure. so if a provider uses one term over the other dont worry that youre getting something different, ask them directly about their device and needle depth since thats what really matters for results rather than which name they use
