Strange lips visual bug

[Blinder]

Hi there.
First time posting,since most of the time I can find a solution to a SSE problem by myself,but this one has me baffled.
Been scouring the internets for a day to find a fix,to no avail.

So,my problem:
I get this weird visual cornery thingy underneath my character's lips.
It's visibly ONLY on elven races.Nord-Redguard-Imperial are tottaly fine.

It's visible in both vanilla and high-poly face parts.
Any kind of input would be appreciated.

Things I tried and failed:

Installed and Uninstalled a couple of skin mods,so I was sure it wasn't my skin mod to blame....(SG Body Renewal)
Reinstalled Seductive Lips HD (with the fix for SG ofc).
Checked the Sculpt in Racemenu,for edges to smooth,but they were literraly NONE.
Reinstalled Aesthetic Elves.
Double-checked my load order.

So I am at my wits end.
Thanks!

Well, I found out the cause.
To anyone who is also looking into this,or will look into this, here's the solution:

In your skin's folder (\textures\actors\character) there are a bunch of folders named after races and body parts filled with dds files.

In your elven folders (darkelffemale - highelffemale) there are two dds ones named femalehead_msn.

 

Just throw them in your recycle bin and replace the with the femalehead_msn from your \textures\actors\character\female folder.

Simple copy & paste, nothing more.

And Ta-da! Profit!

My character looks awesome as ever!
