The only women's bath product I really see a difference with is those jarred creams with abrasive material in them (like strawberry seeds or sugar; not micro plastic beads). They're the only thing aside from Lava brand hand soap that actually exfoliates my skin so I don't have weird hard spots of gunk in my pores along the outside of my thighs. My ass is so, so smooth now.
Can also vouch for shae butter + walnut shells. One of my friends makes them for fun and they leave you smooooth. Might not be good for pores though, especially for oily skinned folks. I'm basically 50% paper man, so I need all the moisture I can get.
Also gotta be careful with oils in the bathtub/shower. They leave the floor deadly slick.
