How to bring polygons on a 3d model (Blender 3D) to a normal view for subsequent animation?

Question

3D

Making my first serious 3d model (human, high poly). It turns out quite tolerably (when smoothing), but the trouble with polygons is triangles, curved-oblique quadrangles, somewhere (for example, on the eyelids) there are a lot of them and they are very small. I read that the wrong topology will lead to animation problems. So, is it possible to correct the topology without losing shape using blender or additional modifiers? I like the result, but I really want to animate
Thanks in advance for the answers

Answer 1

Try
remesh modifiers
Simplify
and then subdivide the surface from above
And do not use high-poly meshes in animation at all, make a second model on top of the high-poly one, then bake normals and textures, do rigging and your high-poly model will be indistinguishable from a normal one that will not eat a lot of resources....
