You won't do your eyelashes any good with an eyelash curler. They are mechanically and roughly pressed into the desired shape. The effect only lasts for a short time and your eyelashes can break. Lash lifting, on the other hand, works like this: The Lashlift Lotion #1 gently opens the structure of the eyelashes. Once brought into the desired shape, the structure is closed again with Lashlift Lotion #2. The effect lasts 6-8 weeks depending on eyelash growth.
