Eyelash serum prescribed by a doctor to support healthy eyelashes. - Brand: EMAKED - Tested: Ophthalmologist Tested - Product Type: Eyelash Serum - Formula: Physician Formulated ✿ For those concerned about pigmentation, applying a thin layer to the lash line is less likely to cause pigmentation. I have been using it, and my eyelashes have gradually become thicker and longer, so I think it works, although the effects may vary from person to person. Thank you for viewing. Please refrain from purchasing if you are overly sensitive. m(_ _)m
