This is the first eyelash serum I've tried, I couldn't compare it with any eyelashes serum in the market. The serum is easy to apply using the dual brush, the ball-tips brush is very helpful for the serum to reach the eyelash roots easily, useful for lower lashes, while the screw brush helps the serum to spread evenly in between each lash. The liquid is unscented, lightweight, not sticky as it has non-oily formulation, the watery texture feels so refreshing (be extra careful when applied, wash with water if it gets into the eyes).
After about three weeks of applying this serum, the eyelash grows slightly thicker and longer, I could notice the lower lashes had grown a bit longer, compared to previously almost unnoticeable lower lashes, (too short and thin) and now they're slowly coming back. I'm excited to see how long it will grow until this serum gets empty. I'm happy to use this serum every day without burden because it is comfortable and not irritating the sensitive skin on eye areas. It is stated that this serum could also be used for thin eyebrows and hairline but I didn't try anywhere else except for the eyelashes.
