Eyelash extensions, false and magnetic eyelashes, and even some mascaras can all weaken lashes over time. This is why I prefer eyelash serums. My eyelashes thinned after my second pregnancy and I'm thankful that GrandeLASH helped. I do recommend using these products cautiously, not over applying and taking breaks after a few months!! Thanks to @marieclaire for talking about this and rounding up the best serums that can help your lashes shine! #lashes #eyelashes #lashhealth #hair #hairhealth #hairgrowth #eyelashserum #growthserum #boardcertifieddermatologist
