Display date in dd/mm/yy format, not whole number, in a vlookup

I need to see a "dd/mm/yy" format in my TextBox, but a whole number is appearing.

I tried some dd/mm/yy in the code, but it doesn't solve the problem.

Me.txtDate.Value = Application.WorksheetFunction.VLookup(AssetTag, Sheets("Assets").Range("A2:N1087"), 9, 0)
