Bad "lines" when print almost horizontal surface on bottom of model

Hello, i would like to ask, if there is any solution for this. I was printing head of a funko-pop figure with 0.2mm layer height with PLA material.

It needed supports at its bottom side. I have used organic supports on build plate in Prusa Slicer. After printing and removing supports, there was plenty of filament "lines" stuck there which can be hardly removed, or cant be removed at all. Its mainly at the very bottom, where angle toward print plate is very sharp and gaps between layers are biggest.

I have cut the original model to made only its bottom portion for testing. I tried Variable Layer Height in Prusa Slicer at those places, setting it to lowest layer height it allowed (0.07mm, green portion of the model) for problematic part of the model, but it went the same. I have to use grid type supports as Prusa Slicer told me that organic supports arent compatible with variable layer height print.

Is there any way to improve or solve this and print that portion of the model nicely round? Thanks
