This serum is a pricier pick, but it contains proven skincare ingredients to help weak eyelashes grow stronger and longer in as little as 30 days.  Are eyelash growth serums safe? Hello- I stopped using R&F lash boost about a year ago because I just didn't want to pay for it anymore. Since then, my lashes have been feeling out. They grow back but seem to cycle every couple of months they will all fall out again. I have been to several doctors to check blood levels and everything has come back normal. Could this be related to the lash boost and if so, when will it stop? I have not been able to wear makeup for about a year because when I take mascara off, I loose so many lashes, it just isn't worth it. Please tell me there is an end in sight.

Lash serums are packed with enriching ingredients designed to both strengthen the lashes and potentially stimulate growth. So the point of them is to nourish, fortify and even lengthen your natural lashes. Pure Organic Castor Oil Without Any Bells Or Whistles Neutrogena’s eyelash growth serum is another affordable option that promises results in as little as four weeks. It’s infused with biotin and peptides and includes a fine-tip applicator that you use twice daily. The lash serum is ophthalmologist tested, with 9 in 10 women reporting better-looking lashes in four weeks.
