Lips shading, how can i improve the transition between the face and the lips?

When i make adjustments to the lips, reflectivity or gamma or other stuff the seam between the face and lips becomes sharper and more obvious, how can i reduce this effect so its a cleaner seperation?

Instead of fixed values for dual lobe, you can plug in some textures and paint them to smudge the borders.

Do you have an example of how I could do that or what it would look like? im not sure exactly what this means.

is this what you meant?

1. Create a new image (2048x2048, 32-bit float, black background)
2. Connect Image Texture's Color output → Dual Lobe Weight input
3. Switch to Texture Paint workspace, select this image as active
4. Set brush to Soft/Airbrush, low strength
5. Paint white-to-black gradient across the lip-face boundary to blend the values smoothly

Yes, you can then use that texture as a multiplier for any lips channel.
