Review of Rimmel Lash Accelerator Serum by gerlygerl
After having success with the more expensive Physicians Formula Last Boost Serum, I realized that this Rimmel lash serum has the same active ingredient as the PF serum (Myristoyl Pentapeptide 17) plus some other goodies like caffeine, which is supposedly good for stimulating hair growth in general though I've only ever seen it used before in products made for the hair on your head.
Results: My lashes are longer and stronger. They don't fall out as often, which is great! It took a few weeks to notice a difference, but since it's so quick and easy to apply at night, and the product isn't too expensive (<$10), I kept at it. My tube has lasted me 4+ months, and I still have probably 1/5 left, so you get a lot for your money.
Compared to Physicians Formula Last Boost Serum: The PF serum, which I've used in clear, doesn't sting quite as often as the Rimmel can, but both have given me the same results. The PF is thinner, which is both good and bad - that means it can be used 2x a day including in the AM under makeup without issues (I never had any), but it also meant that I was never sure that my lash line was coated enough.
Both products are great, but for me, Rimmel has the edge due to the addition of ingredients like caffeine, biotin, sodium hyaluronate, and an additional peptide, Biotinoyl Tripeptide 1.
