Why beauty products suit CGI ads
Three things make perfume and skincare hard to shoot. Glass shows everything around it, so much of a shoot goes on controlling reflections. Liquid and cream move and change, so a good splash takes many attempts. The product is small, so a macro photograph has very little in focus.
In 3D these are choices. A reflection is a light we place. A splash is a simulation, which is a calculated version of how liquid moves, and it can be run again with a different shape. Focus is set where we want it. This is why CGI for beauty products is common in fragrance and skincare advertising, and why a perfume CGI video can show a bottle rising through liquid or locked in ice.
