What the gurus are saying

A brush that lets you place lash glue precisely is what keeps winning fans, along with a reputation as one of the most accessible glues around. Gurus say a few uses can be squeezed from one set of lashes if you let the glue go tacky first. The catch: one clear batch reportedly dried visibly tinted, so patch-test before the big day.

"I'm going to use my beloved geo glue. And I'm just going to take my time. So, look, they're like tiny little sprigs of lash. And because they're so small, the glue dries pretty quick. So, I can just pop them on. I'm actually going to take some of that duo glue on the back of my hand. Not ideal to get off, but it makes it so much faster. And then I can just dip into the glue on my hand and then apply the little lash."

"I love using the Duo lash adhesive and have used it for years. They make a dark glue and a clear glue, and because I have a soft lash line I chose the clear. But this time the clear glue is not drying clear, which has never happened to me before, so [...] maybe I got a bad batch. I wish I'd used the dark glue and had to cover the lash line with liner. Let this be a lesson to test your glue before the day of."

"This is the Duo Brush On Lash Adhesive and this one works really great for me. You need lashes and you need a lash glue and with these types you can get at least like five uses out of them."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Retinoids

Retinoids are among the best studied ingredients in dermatology, with solid evidence for acne and for the fine lines and rough texture that come from sun exposure. Dryness and flaking in the first few weeks are common and usually settle.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.

Vitamin E

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
