One pencil for three steps of eye makeup
The Double Effect Waterproof Eye Pencil brings together three steps of Korean eye makeup. It can be used as an eyeliner, blended over the lid as a shadow, or applied under the lower lash line to define the aegyo-sal, the soft, slightly raised area beneath the eyes that is a signature of the Korean makeup look.
The seven shades for Amazon US range from defined to soft. They include 01 Midnight Black, 03 Cinnamon Mocha, 04 Glam Latte, 05 Champagne Gold, 06 Baby Peach, 07 Matte Black and 08 Matte Brown, covering both shimmer and matte finishes. The pencil has earned more than 290,000 reviews with an average rating of 4.7.
Wear assessed in independent studies
The pencil’s wear was assessed in a 24-hour study by Intertek Korea, conducted on the forearm. In the study, 95% of participants said the pencil did not come off with water or sweat. A separate waterproof evaluation was conducted by P&K, also on the forearm.
