It's working great so far! [SEP] I have been using GrandeLash for over a year now with a lot of success. So I don't know how this product works for first time users. The only thing I can say is that this product is maintaining the outgrowth I have from using the other brand just fine. I haven't had any eye stigmas or irritaton from this serum either. I have been using it for over a month now and I like it a lot. I would have to recommend it.
