1. An absorbent article configured to transfer an active agent to a wearer, the absorbent article comprising:

  • a liquid-permeable layer;

    a liquid-impermeable layer;

    an absorbent core positioned between the liquid-permeable layer and the liquid-impermeable layer; and

    a compressed substrate positioned between the liquid-permeable layer and the liquid-impermeable layer, wherein the compressed substrate defines a x-direction, a y-direction, a z-direction, and an altered upper surface, the altered upper surface defining an initial surface area, wherein the compressed substrate comprises a compression molded web and an active agent, wherein the compressed substrate is configured to expand in the z-direction upon contact with a liquid to form an expanded substrate without substantially expanding in either the x-direction or the y-direction, and wherein the altered upper surface of the expanded substrate has an expanded surface area that is at least about 110% of the initial surface area of the compressed substrate.
