The Bye Panda Eyes! Vol. Def. Mascara by essence is a tubing mascara that Harper highly recommends. In their video review, Harper mentions that this mascara is great for achieving a clean girl makeup look. They demonstrate the difference between applying the mascara with and without curling the lashes, noting that curling significantly improves the results. Harper applies a second coat and states that it looks even better. Overall, Harper suggests curling the lashes before using this mascara and believes it is worth recommending. The mascara's tubing formula ensures easy application in small tubes. However, since Harper did not compare it to other tubing mascaras, it is difficult to assess its performance in comparison to similar products.
