That's great, is it not okay to stop using the product when the desired length is achieved?I have tried other brands of lash growth product and they have all made my eyes itch. Dermal md and this Pro version don't cause me any issues and my lashes are longer! It goes on easily and I have been using it every night. Now that my lashes are at the length I like I will switch to every other night like I did with the original formula.
