If you're struggling to convince Flux to generate a photo of a woman who looks under 30, this is the LoRA you need. It otherwise won't mess with your images too much, and, much like vanilla flux, it's mostly idealized (there are already Flux loras that generate more realistic photo portraits, and that's not what I was aiming for here). Flux seems to have a lower age limit on people in photo generations of like 27 or so. This LoRA changes that to 18-22. Turn the strength up beyond 1 and it'll make people look more idealized, but not under 18
