The formula is supposed to have "buildable" coverage that is "hydrating" and will help "smooth out the skin's texture." The doefoot applicator made it practical to apply the highlighter onto the face for spot highlighting, but for those who prefer to mix a liquid highlighter into other products (like primer, moisturizer, and foundation), it may not be as useful as a dropper, though I think you can get enough product off the doefoot applicator for mixing if desired.
The highlighter was thin enough to feel like a liquid, work for spot highlighting or mixing in with other products, but still had medium pigmentation. It spread beautifully over the skin with a brush or fingertips, though I prefer fingertips when working over a base (like foundation) to gently pat and spread the product and using the edges of my fingertip to diffuse the highlighter. The formula did exceptionally well over foundation and never lifted mine up (and I used some drier, more matte formulas with it). The highlighters lasted between eight and nine hours on me.
I was surprised that the product actually came in a glass bottle, as I would have expected plastic, and in a way, I might have preferred plastic for fear of the glass breaking in a bag, though it's not uncommon for liquid highlighters to come in a glass bottle.
