Ardell Professional Magnetic Gel Liner makes false eyelash application less stressful. The liner's magnetic properties allow the eyelashes to adhere to it, even without traditional lash adhesive.  Key Ingredients The key ingredients include iron oxides that create a magnetic attraction to the eyelashes and a gel liner that provides a smooth application. It contains Methyl Trimethicone, which aids in the rapid drying of the eyeliner and quickly evaporates from the skin. Additionally, the isododecane plays a vital role in ensuring a matte finish and retaining moisture simultaneously. It also causes the eyeliner to spread quickly on the skin with an intense pigment.  Effectiveness This product is also long-lasting, waterproof, and smudge-proof, ensuring that your eyelashes stay in place for an extended period. Additionally, it gives you a smooth and precise finish, which can last for all-day wear. Customer Reviews  According to one customer, the waterproof gel eyeliner is difficult to remove, even with coconut oil. It is also thicker and harder to apply, but the brush can help.
