All three of these bottles have 30ml of product, but I thought that it was really interesting that the Ole Henrikson bottle was HUGE. That being said, the Ole Henrikson bottle is airless so it’s not going to oxidize the product as you’re using it.
Does packaging make a difference in what you buy? I know we feel that dropper bottles are more science-like and so the stuff inside must be better, but you’re letting air into a product every time you use a dropper bottle and that might not be a good thing. Vitamin C is unstable to light so… something to keep in mind when you’re purchasing it.
