If she really does use Transmutation (can be Conjuration), it involves the creation of an aura construct or tangible shape and this can then "compress" her body. The matter was not altered by the aura but by the pressure of the construct. Emission, for example, does not change matter by definition, but can blow things up into small pieces of the same matter that the thing hitted was composed initially.

The two basic types of abilities of a Transmuter don't match with Texture Surprise, not without the explanation being unnecessarily more complicated and stretched than with the use of Conjuration. Also, if Hisoka changes the matter with his aura, how could he managed to use Texture Surprise on his false limbs which are incontestably made of aura?
