Not likely. All our lashes grow to a certain length naturally on their own. RbyNLash®, not only supports that growth, it strengthens, fortifies, and conditions the lashes to help maintain the growth during its normal growth cycle. Chemical-laced lash serums use ingredients such as bimatoprost or prostaglandin analogs to force the lashes to grow outside of their natural growth cycle, which can cause lashes to fall out or even break when stopping those products.
