Hi April! Thank you for your interest in the Lash Sensational Boosting Eyelash Serum. Yes, you can use this product on both sides of your lashes. For best results, use this product twice a day, in the morning and at night. Then, apply a layer of the serum to lashes, from root to tip and along the base. Allow to dry before applying mascara. We hope these tips helped and you can continue to use our products with great satisfaction!
