The video features a woman demonstrating how to apply eyeliner. She starts by applying a base layer of eyeliner on her upper eyelid, then proceeds to add a second layer on top of the first one. The woman uses a brush to blend the two layers together, creating a smooth and even finish. She then applies the same technique to her lower eyelid, using a smaller brush to achieve a more precise and detailed look. Throughout the video, the woman provides clear and concise instructions, making it easy for viewers to follow along and replicate the technique.
