DOES ACTIVATED CARBON STILL WORK IN SOAPS, SHAMPOOS, TOOTHPASTES, &C.??

If activated carbon works by adsorption, how can it still adsorb skin grease, bacteria, dead skin cells, &c., if it's already incorporated into the wet gunk; i.e., the shampoo or whatever? I can understand putting activated c in foot powder since it's dry, but won't mixing it into a wet product plug up the pores and prevent adsorption on the skin? Thanks a million in advance for the answer! :D Can't find anything on Google about this... Never bought anything with act. c in it --- except for foot powder --- for the past five years since my secondary level teacher broached this topic in class...
