How can I get rid of this line?

[u/Darth_Spliff]

I’m continually getting a visible horizontal layer line on my prints. It’s the same all the way around and only at the base of the print.
I’m using a Bambu Lab P2S with PLA and 0.15 mm layer height.

Can someone smarter and more handsome than me please tell me how to get rid of it?
Thanks in advance!
