While it does not provide as many options for advanced selections and photo manipulations as Photoshop, Lightroom has a number of tools that allow you to do the majority of your post processing without needing to open Photoshop. Lightroom 5 introduced the radial filter, and there were some small enhancements made to it in Lightroom 6/CC. The radial filter can be used to make selective adjustments quite easily for a wide variety of different purposes. In this video Simon Plant provides an introduction to the radial filter and shows how it can be used to improve a sample photo. If you are not very familiar with the radial filter or if you rarely use it with your photos, this is a video that may be of great help to you.
