Fuller, Stronger, Longer Safe for lash extensions! PLA’s first Lash and Brow Serum is here! The application of our eyelash growth serum at the base of the eyelashes results in the extension of the Anagen stage of the growth cycle, thereby lengthening and volumizing the eyelashes! Our product was tested in a clinical trial with proven results showing positive effect on eyelashes after consistent use. Directions Apply twice daily, once in the morning and once in the evening. Stroke the serum on to your eyelid. Apply along the lash line, similar to a liquid eyeliner. Replenish applicator for each eye. Allow to dry for 1-2 minutes. Results may vary.
