longer lashes but not thicker or denser [SEP] i used this butecare serum for months to write this reviewthings i liked i did not notice a change in density of lashes or thickness of existing lashes the serum is watery so i had to gently massage it in after applying otherwise it moved like tears on my eyelids i woke up in the mornings with sand like dried particles in the corners of my eyes which i do not normally experience when i am not using this product
