Cellulite or lax skin? Can this only be treated with Qwo? (Photo)

I have seen two people (a surgeon and a nurse injector) and both claimed that these horizontal lines on my thighs are long cellulite bands that could be eliminated with only a couple rounds of qwo. I am worried after seeing such bad reviews on qwo and only about 50% of people saying it's worth it. I am also not sure if this is actually bands or if this is likely lax skin. Any advice?? (Please overlook the small lump on my left buttocks as that is herniated fat from a past injury and not part of the horizontal lines I am talking about)
