There are so many eyelash and brow growth products on the market that they are beginning to merge together. In some cases, quite literally: Cilea and Nutra-Lift Lash Renue are identical. Now Fusion Beauty’s StimuLashFusion Intensive Night Conditioning Lash Enhancer ($89) has arrived and it took me an hour or so, but eventually I discovered that it is more or less the same as Skin Blends Lashes LTD.

Actually, it is – apart from a teensy reordering at the end of the ingredients list – the same thing and will be added to our list of product twins (identical formulas marketed by different brands and with widely differing price points). And, it turns out to be my first product triplet. Yep, it is also identical to NutraLuxe Lash ($79). In this case, you will save yourself nearly $20 by buying LTD rather than StimuLashFusion. Personally, I don’t care for any of them since the active ingredient is a prostaglandin, methylamido dihydro noralfaprostal, derivative with potentially unpleasant side effects.

Both StimuLashFusion and LTD have seem to have begged and borrowed from several other products. There isn’t necessarily anything wrong with that. Some of the ingredients that it has picked out seem to work in other products. For example, Hydropeptide Lash (which I tested successfully and nominated a TIA best product of 2009) has several hexapeptides, although not specifically the hexapeptide 11 that is in StimuLashFusion. You can also find a hexapeptide in ModelCo. While we are on the subject of peptides, it also has Matrixyl (palmitoyl pentapeptide-4), although I haven’t found any evidence that it stimulates hair growth.

Like Rapid Lash and many other eyelash growth products (check out our round up), StimuLashFusion has hydrolyzed glycosaminoglycans, which binds well with water and helps keep things moisturized. Pumpkin seed is in some other recent newcomers, Cilea and Nutra-Lift Lash Renue.

Whether StimuLashFusion will make your eyelashes grow remains to be seen, but you can be sure that you’ll be seeing double.
