No, no at all. The skin is such a huge organ, subcision deals with only a small part of it. It won't cause drastic changes, except for shallower scars, that is.

Skinnystrong, I'm just wondering if you've had experience with subcision specifically because a DR. actually told me it can thicken the dermis over time when used in conjunction with PRP or fillers. I'm not sure if this is a good or bad thing tho.

Yes I have experience with subcision. "Thicken the dermis" may be the phenomenon some describe as the "donut effect"? Where the scar is overcorrected because of the filler? Am I right? If so, it really is a matter of controlling the filler amount, and giving your skin time to recover in between sessions.

And that's also the general rule in any skin treatment - treatment, rest, treatment, rest. Over doing too many things in a short space of time, like within a month, will cause skin issues.
