Final answer:
For wide-set eyes, define the inner parts of the brows to make them seem closer, while for close-set eyes, extend the tails of the brows outwards and use lighter shades to create the illusion of wider space between the eyes. Brow gels, powders, and pencils help achieve these effects and create fuller brows.
Step-by-step explanation:
For individuals with wide-set eyes, the goal in defining eyebrows is often to create a sense of closer proximity between the eyes. This can be achieved by defining the inner parts of the brows more heavily, using eyebrow pencils or shaders to bring the start of each brow slightly closer than where the natural brow begins. It's also important not to extend the tail of the brows too far out, as this can accentuate the wide-set nature of the eyes.
Conversely, for those with close-set eyes, the approach involves creating the illusion of a wider space between the eyes. This can be done by being more conservative with adding definition to the inner edges of the brows and instead focusing on extending the tails of the brows outward with a brow pencil or powder. Brow gels can be used to keep the hairs in place and to add texture, particularly toward the outside of the brows, to further the effect of widened eyes. Applying a lighter shade of brow powder or eye shadow in the inner corners can also help enhance this effect, giving a more natural look to the brows while also playing with the perceived distance between the eyes.
