Good to know. I'm coming to the end of my second tube of Jan Marini Lash (original formulation). I was wondering what I was going to use next because the original JM is getting harder and harder to find because they are expiring. I have read that the new JM lash product is not as effective. I was going to try Latisse, but maybe LiLash will do the trick. And, yes, your lashes do go back to normal when you quit using these types of products. I took a short break in between my tubes of JM and my long lashes thinned out/fell out back to the way they were before.
