[Help] Removing lips from making holes on a diagonal surface

Hi, I’ve been making a microphone to improve my modelling skills, and am currently making the handle portion of the mic. However, I’m noticing that little “lips” are created along the surface due to the mesh structure and application of the subdivision surface modifier, as seen in Figure 1. How can I go about solving this issue?

Thank you in advance!
