What I really love about this formula is that it contains growth factors, biotin, and peptides which help strengthen and promote healthy growth. Boasting visible results in up to 8 weeks, the RapidLash ®Eyelash Enhancing Serum is an effective, yet gentle lash serum, designed to promote longer and fuller-looking lashes. It helps hair grow stronger, thicker, and longer in the long term and the reviews speak for themselves. The serum is enriched with Hexatein 1 Complex, a uniquely-concocted blend of six high-performance ingredients: peptides, biotin, amino acids, panthenol, soybean oil and pumpkin seed extract.

So many lash serums on the market use them (the main one being Latisse) so it's just something to look out for if you have sensitive skin or eyes.

This innovative high-performance serum formulated with advanced polypeptides helps enhance the appearance of lashes with a simple once a day application. Utilizing our exclusive Hexatein® 1 Complex, RapidLash® targets the eyelash needs from every angle: from moisturizing factors and nourishment, to boosting the appearance of more voluminous-looking lashes.

These serums for the brow and lash growth help reduce shedding while supporting the body's ability to anchor the lash and brow follicle to the root system.I have several friends who use it and completely swear by it (they have the best lashes of out anyone I know), but it's only available via prescription which can be a bit of a pain.

GrandeLash has gained a cult following over the years (especially among WWW staffers) because it really works. Although it took me a while, I now have a solid handful of serums that really help out my normally short, sparse lashes. The consumer studies indicate an agreement rate of 88% in improvement in the appearance of lashes, and 86% agreement rate in fuller, thicker, stronger and longer looking lashes.
