Pianting normals creates artifacts

I've been trying to correct some small imperfections in the normal map using Substance Painter, but every time I paint, small artifacts end up appearing (they look like small grey-ish dots).
It's not immediate either; they take a while to show up and can be painted over, but they reappear regardless. Any idea what could be causing this?

Hi! I can't tell what's causing the spots. Honestly, in this situation, I would simply adjust the model so it bakes nice in the first place. The baked normal map shows gradients in that area so getting values right painting is impossible and will likely show in the shading. And every time you tweak the model and re-bake,  you will also have to re-paint.

Okey, thanks! I'll adjust the low poly then.

You might have to tweak both, high and low. But it's a bit hard to get the full context from the images shared.

With unwanted projections from adjacent geometry, I'd look into Painters "match by name".
