Yes indeed. Acetone goes deep. Deeper than Eddie Murphy going undercover in Bevery Hills Cop.
It can also shrink. A lot! Ive done many tests on this. Its why you need to be very careful with exposure times and why brushing is less prone to warping than dipping which can play havok with hollow models.

These photos show the effect of acetone on a part that I left on purpose in acetone for way too long (more than an hour), just to try what would happen. It got weak, lost its spring-effect, and cracked. Its strenght recovered somewhat in the next months when drying, but not fully. Now I broke it.
So you can see how deep the acetone penetrated and cracked the model. The inside seems to be still chemically affected, as it broke in a weird way, with very different inner and outer fracture surfaces. This is yellow PLA/PHA from colorFabb. The fracture surface is ca. 6mm x 4mm.
