Best eyebrow serums

I recently posted here a few months back to improve my eyelash and eyebrow length. I've looked on Amazon at Augustinus Bader, Obagi, & Rodan + Fields serums. Augustinus Bader has mixed reviews, Obagi is exclusively eyelashes, and Rodan + Fields only has reviews on Amazon for lashes growth in lashes.

I really want to grow out my eyebrows to shape them better! I used to shave them but I never got enough arch. I also have a bald spot from a childhood injury on my left brow.

Would love recommendations for brow serums that work please!
