This is a slider Lora, so you can choose whatever weight you want, so experiment and find what suits you best. A positive weight makes the character older.
The mature version makes the character look mature/younger without going all the way to make them look very old.
"Old" version works the same on the younger side, but makes the character look extremely old.
(Check the preview images to see the example.)
Recommended weight: from -2 to 2+
No trigger word is needed
