Refillable Skincare Packaging Product Research Survey

Hi all,

I am an Industrial Design student currently doing my final major project on a refillable packaging solution for a premium skincare product, for the next stage of the design I need to verify what refilling route I should go down. As a result I have created a survey to help me validate my decision and would love to get the most amount of responses as possible and would appreciate any help. This is the link to survey

Thank you all. Furthermore this is an interesting product that has inspired this project which is available in the UK. Are there any other refillable packaging solutions you guys have come across?
