Does Latisse Work Better Than Revitalash?

My suggestion would be to use up your Revitalash (we used to sell it but no longer do) and then switch to Latisse.
Latisse is the same price (actually $5 cheaper than we used to sell Revitalash for) and it works better because the active ingredient that is used in Latisse was removed from Revitalash in the recent past based on a lawsuit between the two companies that produce the products.

There are many over-the-counter eyelash products available.  Latisse is the only prescription strength one available and the most popular we carry in OC Dermatology.  While some of the other products (called "lash conditioners") work well to grow lashes, nothing grows them as long as Latisse.  If the other products did work as well, than they are illegally including prescription bimatoprost (or a similar prescription product) in the formula, which would make it a prescription product if not legitimately. 

We have have carried both in our office, however, currently only sell Latisse. We have had a higher patient satisfaction with Latisse.

Latisse is approved by the FDA and grow eyelashes longer, thicker , and darker.  Revitalash grows eyelashes longer and thicker but not darker. The onset time for Latisse is different for each patient.

Both products work. Latisse has been studied and has passed FDA approval. There are controls in place in Latisse production because of the FDA regulation that ensures that the product you purchase is sterile and has the specified amount of active ingredient in it. I am not knocking Revitalash, I used it before Latisse was available, but it is not FDA approved and therefore not as carefully regulated. If your Revitalash is fresh, it is hard to suggest throwing it out, it is expensive. I would recommend switching to Latisse when you need more product
