Unlike eyeliner, only the hairline is thickened during eyelash line thickening, which creates a more open look and makes you look fresher in the morning. Another aspect is that eyelash line enhancement can also be left to fade again without hesitation if you decide against it at some point. Why don't I offer eyeliner? If you opt for eyeliner, you will have it forever. Unlike eyebrows, for example, you can neither have this area of the eye lasered nor use a remover, and an eyelid line that still opens the eye at the age of 25 can also make it look droopy at the age of 55.
