Equipment does matter to some extent, but you're right to be skeptical of marketing. The Cutera XEO is a legitimate medical-grade laser system that's been around for years and has a good track record for vascular treatments. What makes it effective is the specific wavelength it uses, which targets blood vessels efficiently while minimizing damage to surrounding tissue. However, the skill of the practitioner matters just as much, if not more, than the equipment itself. When choosing a provider, look for someone with proper credentials, plenty of experience specifically with vein treatments, before-and-after photos of their work, and someone who takes time during consultation to assess your individual needs rather than pushing a one-size-fits-all approach.
