Strengths: Inexpensive compared to prescription lash-growth product Latisse; works on eyelashes and eyebrows.
Weaknesses: Given that the "active" cosmetic ingredient in RapidLash bears a chemical similarity to the drug ingredient in Latisse, it is possible, though not proven, that RapidLash could have the same side effects. Those side effects include stinging or burning along the lashline, redness at application site, and potential discoloration of the iris. Again, these side effects are potential issues based on how RapidLash is suspected to work. They should not be construed as a given or as a recommendation to avoid using RapidLash; rather, they are something to watch out for and, should they occur, discontinuing usage of RapidLash is advised (something the company behind RapidLash states in their product brochure).
