I generally tend to include mine in my mods just in case anyone wants it. For The Elder Scrolls V: Skyrim Special Edition on the PC, a GameFAQs Q&A question titled 'Anyone know a mod that allows permanent edit to an NPC's appearance Neck seam trouble with weight.'. You can use it to make followers with the preset's look, give NPCs the preset look, etc. We are going to use this to make the face of the preset. This will generate a file in your Skyrim installation folder called 'YOURCHARNAME.NPC'. Once you have your character looking like how you want the preset to look, hit the tilde key, otherwise known as '~', and type 'SPF YOURCHARNAME', of course substituting the 'YOURCHARNAME' for the name of your character. You can decide whether or not to save your game after this it doesn't really matter in the grand scheme of things.
Make sure that you are out of the ShowRaceMenu. RaceMenu allows you to modify your characters with greater detail. However, you can download SkyUI and RaceMenu to go with it. Create a character that you would like to share, or open your old save. The only way to change the appearance of NPC or replace it is mods. There is no point in having an empty mod enabled. Whatever you named your mod, you need to go to the mod manager you are using, whether it be the launcher or the Nexus Mod Manager, and uncheck your mod in the load order. I named my mod Solding_CharPreset for the character I am going to be sharing. When you are finished saving, exit out of your Creation Kit.
