Clear VS Dark Eyelash Glue... What's the difference?

(Just as a note, I am specifically talking about Duo lash glue in this post. I have not used some of the new brush on lash glues that are coming out, so this post does not reflect those)

When 99% of people use clear eyelash glue, you may wonder to yourself why they even make a dark one or what the purpose for it is. I mean if it dries clear why would you want to put something dark on instead? It could smear & leave ugly dark smears everywhere, right?
I used to think the exact same way. I only used the clear Duo & didn't get the purpose of a dark lash glue at all.
Then one day I came across > this < blog post by Makeup By RenRen. One sentence changed my life " If you use clear glue, make sure to go over any shiny spots with black liquid liner. " This was something compleatly foreign to me. I hadn't really thought about the fact that clear lash glue was shiny before. The next day I searched my local beauty store for dark lash glue & it was not as easy to find as I thought. Even though many stores carried Duo, few carried the dark one. Eventually I found it at K-mart (of all places & for a far better price too). I went home & tested a small patch on the back of my hand. It dried to to the most beautiful light grey satin finish. It changed my life forever.

So long story short, dark lash glue doesn't leave you with the high shine that comes from traditional clear lash glue. It's great for when you want to add a little bit of extra volume or length with false lashes but don't want to add liner on the top lid to cover up glue patches. It also works great for blending in those pesky shiny clear lash bands that are sometimes hard to cover. It is so much easier to blend over with a little bit of eyeshadow as well. I also find that it makes it much easier to place false lashes right on top of your own lashes & blend them together nicely.
Now, I do use a slightly different technique to putting on my lashes (both on myself & clients), which may make it easier for me to use dark glue to begin with. I will put a link to the video below that shows how I do it (I use disposable eyeliner brushes so I can just toss them instead of trying to get out the lash glue)
All in all, I almost exclusively use dark tones lash glue now & find it to be a much better option in so many different ways.

I hope that this helped some of you & that you give the dark lash glue a second look now.
