Inducing a "diffusion"-like blur to smoothen sharp data peaks

Hi there, I'm currently working on a 2D-axisym. model of a droplet on a wall. The droplet consists of a certain species which starts building depositions on the wall, where the concentration of that species on the droplet-wall-interface is >50%.
The problem is that the meshpoints on the wall, where the species concentration is >50% are not very well distributed (only 1 / 2 meshpoints do have concentration >50%) and so there are really high, rather "unphysical" peaks of the concentration. So depositions are also build badly distributed.
At the moment to solve this issue I've induced a normal distribution (gaussian) to the concentration to get better distributed depositions. But this step of course is also "unphysical".
So my question is:
Is there a possibility to blur the >50% concentration peaks, so that it "diffuses" to the adjacent meshpoints as well? (As it would do when I solved a diffusion-equation for the problem itself) The blur should only affect the deposition building, but not backfire on the concentration itself.
Thank you very much in advance! I searched in the COMSOL community for approaches but I couldn't find any.
