-> Normally, i fixed a black eye at first. As it shows in comparison screenies (at the end), a little graze near the nose is visible. In fact, speaking of bruises, i removed excessive unwanted spots and improved the quality for a black eye. I did the same for the rest.

-> This is the mask map (Alpha) which covers bitmap/diffuse up. For example, at black eye, These gray spots don't show much in game, while white ones do. The more spots turning black, the more you see less visible.

-> The area extended, unwanted spots, too 'sharpened' details,... i improved all of them, on both mask and bitmap. Depending on bruise areas like 12 rounds (full face), i didn't remove most excessive areas, as it's more than getting punched all sides of face.

-> This works with LMCC. If you want to make your own overlays with tints, check at sample api tint injections. Make sure your overlay orders don't conflict with mine at the same id's, as long as you have this mod installed.

-> I use id: 33 for custom category. For templates, tints, id: 27502 - 27539.

-> 3 types (Colors): Fixed, improved and Blood. For black eye, broken nose, fat lip, 12 rounds.

*Note that you can use many overlays at once, but always make sure you adjust opacity against excessive bruising tints!

-> Install Looksmenu, and then this mod. Install it with your manager, select options with FOMOD, all done.
-> Once you open your game, in console command, type: SLM 14. If you have your NPC/companion, SLM "copy Your highlighted code here", no quotes.
-> Open "Extras", find "Facial Damage Fixes", add bruises, adjust opacity, whatever you want. Save and exit.
