Revitalash is one of the first eyelash enhancers that hit my radar. It was developed by an opthalmologist whose wife had lost her lashes due to chemotherapy for breast cancer. It is considered a cosmetic product, so is sold over the counter.

At over $100 a tube, Revitalash is, by far, one of the most expensive otc products, likely because it was the first to market, though I am guessing the cost will go down as competitors come up with similar products.

My sister used this product and her eyelashes DO look longer and thicker, so at least I've seen proof that it works.
