In cosmetic arts, which technique is commonly used to enhance the eyes?

The technique commonly used to enhance the eyes is eye shadow application. This method involves adding color and dimension to the eyelids, which can help define the eye shape, complement the overall makeup look, and draw attention to the eyes. Eye shadow can be applied in various styles, textures, and colors to create different effects, ranging from subtle and natural to bold and dramatic.

In contrast, eyebrow tinting primarily focuses on altering the color of the eyebrows, which can frame the eyes but does not enhance the eyes directly. Facial waxing is a hair removal method that targets other areas of the face and does not specifically apply to eye enhancement. Hair highlighting is related to enhancing the hair by adding lighter shades but does not have any direct impact on the eyes. Therefore, eye shadow application is recognized as the most effective method for enhancing the eyes in cosmetic arts.
