Which filler is better, Neauvia or Skinfill?

Neither of the products you name ate FDA approved for injection in the United States.

Speaking generally, there is no 'best filler'. The 'best choice' depends on several factors including the region to be injected, the technique to be used, the planned depth of filler placement, the skill, reputation and experience of the injector, and the desired duration of correction. I would suggest you focus more on the person behind the syringe rather than what is in the syringe-that petson should guide you regarding the best filler choice for your specific needs.

Best,
