Revitalash was an absolute game changer for me. I used it religiously each morning (wait a few minutes for the product to dry before applying makeup), and noticed results about 4 weeks in. After about 6 weeks the results were even more dramatic - my lashes are much longer and thicker and have also noticed less breakage after removing mascara. After about 8 weeks I was really happy with the length and volume so started using less (about 3 x a week instead of daily) for maintenance. Could not recommend this product more - I have been asked a few times if I have extensions and even my dad commented on my lashes (so that says something hah!). Tip - a little goes a long way, you only need the tiniest amount. Also, you need to use consistently for 4 weeks, be patient and the results will come.
