Early verdict · Few reviews so farWhat the gurus are saying
The sealed pump and pure-hyaluronic formula with no scent or other additives earn consistent praise, especially from those using it for microneedling, the pump design keeps oxygen out and prevents contamination from repeated dipping. Reviewers also highlight the value, at around $25 for a large container. One thing to keep in mind: both have struggled to find it in stock.
