at can I say this seem like really let my eyelashes getting healthier and strengthen. I have using it around 1 month twice per day. Normally I could see few eyelashes on my face without any signal. But after using this serum, look fall lesser. My eyelashes thicker somemore. The most thing that I love is the ball tip brush. Definitely can apply closely to our hair roots. Freaking amazing! Unfortunately, this do not contain lengthening and curl. 

Overall, this product consider not bad to use. Shall formulate this serum to benefit length and curl.
