The formula is supposed to be a "high-impact, low-maintenance lip stain" with "vibrant, bold color" and a "satin-matte finish." In the initial launch at least, there are only three shades available, and while they were noticeably different initially, they all tended to have more of a fuchsia-like stain left behind that looked more similar than not. Each shade was intensely pigmented with semi-opaque to opaque coverage in a single layer. The consistency was firmer, thinner, and felt almost gel-like as they applied to my lips, and they didn't drag but did need firmer pressure compared to their other lip products (not in a painful or uncomfortable way).
The product was quick to stain, and the stain itself was intense and richer with more coverage--by no means a faint stain or anything resembling a light stain leftover from a more pigmented red lipstick or the like. The stain lingered and lingered into the next morning for two shades, which I had to remove by using a microfiber cloth and remover to get most of the product off.
This product, in general, will work better for someone who is less concerned about wearing drastically different colors from day to day as a result of how long-wearing the stain portion was. The issue I had was that after a second meal, the stain was noticeably uneven and not something I'd want to keep wearing. The lip colors seemed to last five to six hours, while the stain certainly went on and on and was "decent" in how it appeared for another five to seven hours (depending on what one ate/drank and how often). I'd recommend reapplication at that point or tapping some more on the center of lips and blending outward if good wear is necessary for more than that length of time.
They were comfortable to wear, lightly hydrating in the way that it seemed to help my lips retain their moisture over time without adding enough hydration that my lips felt better after 12+ hours of wearing a shade. They had a faint, sweet, lemony scent but no discernible taste. Also, the product is not transfer-proof, but the stain itself is transfer-resistant (some will come away on a napkin).
The average rating based on all reviewed shade(s) in this formula is shown below.
This high-impact, low-maintenance lip stain lays down vibrant, bold color with a satin-matte finish. It combines the precision of a lipstick, the hydration of a balm, and the long-wearing color of a stain.
