Platysmal band Botox at 53 - will it smooth or tighten? (Photos)

Hi, I’m 53 and recently consulted with a local PS for a mini facelift. He was great but did suggest I wait a couple of years. He said these droopy lines on my neck might benefit from Botox. I’m skeptical but I am thinking of trying. I already have microneedling done on face and neck every 3 months. Can these loose bands be tightened or smoothed with Botox?
