Ada reviewed the Vegan Collagen Lash Serum Primer by Pacifica in a video review for Flip. She demonstrated the application process and showed the before and after results. The primer appeared white when applied, but once mascara was added, it blended well. Ada mentioned that the primer can be used alone to promote lash growth or as a base for mascara. Overall, the product seemed to enhance the appearance of her lashes. However, she did not mention any specific benefits or drawbacks of the primer.
