Review on Eyelash Growth Serum Multipurpose Collagen by Carrie Robinson

I bought this product because of a Facebook ad that said I would get a refund for this product. I've tried it a few times and haven't noticed any change in eyelash growth yet - will update if anything changes. It's definitely cheaper than other serums, which are often $80-$90, so that's a plus. I'm thankful it didn't sting my eyeballs at all - some products have been reported to do so, I'll still be careful when applying. I'd say I'm somewhat optimistic at the moment.
