I am venturing into the world of false lashes for the first time and I've just ordered two pairs of Ardell lashes. I'm unsure about which adhesive to purchase. Can anyone recommend a good one? I have heard that Duo is good but I've also heard some horror stories because it contains latex and also apparently formaldehyde. What about the Revlon one? I've heard that this is good as it's latex free but I've also heard it's very messy and hard to remove from the false lashes. Any advice would be much appreciated. TIA.
