Has anyone ever gotten electromagnetic or light therapy done?

My OBGYN just got a so-called "DAFNE system" machine. It is of italian origin and produces treatment with red light, blue light, and more to promote collagen growth, blood supply and tissue regeneration, as well as pelvic muscle strengthening or relaxation. It is mainly used for incontinence and hypertonic pelvic floor issues, but it also has some dedicated programs for vaginal dryness, and for dyspareunia and vestibulodynia.

My gynecologist wants me to do 5 sessions a week apart to start, possibly extending to 5 more.

Is this snake oil or?

I started reading up on it but I honestly can't read so much anymore so here, strangers, share your thoughts
