In the video, a person is seen applying eyeliner to their eyelid. The individual uses a black eyeliner pencil to draw a line along the upper lash line, starting from the inner corner of the eye and extending outward. The person then proceeds to fill in the line, creating a bold and defined look. The eyeliner appears to be of a gel-like consistency, which allows for a smooth and precise application. The person's eyelid is already prepped with eyeshadow, adding depth and dimension to the overall makeup look. The video is shot in close-up, focusing on the eye area, and the person's hand is visible as they apply the eyeliner.
