Hooded eyes occur when excess skin folds over the crease, creating a "hood" that can obscure the eyelid. Treatments like eyelid surgery or non-surgical procedures (e.g., Botox) can help lift the area for a more open look. Makeup tips for hooded eyes include applying matte eyeshadows above the crease, using eyeliner close to the lash line, and blending eyeshadows upward to create the illusion of lifted eyelids.
