How To Use: Step 1: Clean your face and remove eye makeup. Step 2: Apply a thin layer of Xlash on your upper lash line, right on the roots of your lashes. Step 3: Use Xlash daily for at least 28 days, preferably longer. Step 4: Once you have achieved long, full and healthy lashes, using Xlash 2-3 times a week will suffice to maintain your results.
