3d animation

I want to be able to show how my products work on the skin. I would like an animation that zooms into a person's face, and then into the skin, to show the different layers of skin. I then want a before and after, before - showing the skin in a bad condition, and the during/after shows how the products works and leaves the skin in a better state. We will start with one animation but looking to expand this to 5 in total. Something similar to this:

1. Cleanser:
a. Pre product applied:
i. Skin surface: shiny skin surface, reddened skin, groupings of reddened small spots, visibly larger pores.
ii. Underneath skin surface: build-up of dirt, dead skin, excess oil (clogging pores), some clogged pores are inflamed, with bacteria and as a result some have red/inflamed spots, damaged cells.
b. Product applied/post: Show how the water softens the skin and opens pores slightly, then foaming cleanser lifts, dirt and impurities, while also removing excess oil, and leaving a thin layer of moisture. Kills most of the bacteria in the spots, and reduces the redness of spots slightly, and reduces slightly the size of pores visibly, significantly reduces shine/excess oil on the top of the skin. Skin cells start to renew.
