Started using the product about two weeks ago. Haven't seen any noticeable results yet...however, I feel that I need to give it more time. Will update once I've used it for at least 6 weeks. At least I haven't had any adverse side effects, and product is easy to apply. Doesn't sting or smell or anything, just goes on easy like liquid eyeliner. I apply before bedtime nightly. Stay tuned for update in about a month.
