Prostaglandins — they’ve been doing the info-mercial circuit lately, getting in their 15 minutes of lash blasting fame, and RapidLash Eyelash Renewal Serum ($50) is the product du jour!
RapidLash makes some very bold claims…
Potent Polypeptides help amplify the length, thickness and volume! Powerful Polypeptides provide effective protection against breakage and naturally support longer, stronger more voluminous lashes.
Vital proteins and vitamins help replenish and fortify! Panthenol and rich minerals join forces to help replenish and rejuvenate lashes with essential proteins and vitamins that provide strength, shine and enhance lashes.
Moisturizing and rejuvenating agents help add shine and flexibility! Unique moisturizing agents provide extreme hydration to lashes by locking in moisture while improving elasticity and durability.
The product contains bioengineered octa/copper/oligo peptides, an “effective combination of amino acids,” according to CEO Robert Trow, to help “amplify volume by strengthening and rejuvenating” lashes and brows, and isopropyl cloprostenate, a fatty acid (LOL!) derivative, to help “promote cell regeneration.”
I’m thinking about giving it a try, but I’m seeing a couple red flags in the product marketing that make me wonder, like the frequent use of the phrase, “promotes the appearance of,” as in “promotes the appearance of natural lash and brow growth.”
There’s some wiggle room in that sentence. If they’d left out the word “appearance” and had just said “promotes natural lash and brow growth,” I’d feel a lot more confident in the claim.
Used to treat glaucoma, prostaglandin analogues are molecules manufactured to bind to a prostaglandin receptor. They have the side effect of making eyelashes grow, but they can have other less attractive side effects as well, like eye irritation, impaired vision and may even change eye color (eek!). Some lash growth products have even begun marketing themselves as prostaglandin-free.
