Acrylic retarders are made from glycol which slows the drying process by holding on to the water, if you add too much you can get shiny patches and/or tacky paint, the paint can also lift when you paint over it.
If you want to use a retarder I think Winsor & Newton Blending Medium would be a better choice. You get much more if you compare the bottle sizes and price. Works very well together with acrylics.
But I don't use the stuff myself when I'm painting figures.
