Editor's note

Tightlining is the dark art of eye makeup. Done at all, it changes the look. Done well, no one can find what changed. The cut crease works differently: its effect is architectural, and there is no hiding it — the intention is visible or the technique failed.

What 'eye definition' actually means

Eye definition covers any technique that changes how the eye reads in the face — its apparent size, shape, depth, or lift. The goal is the same: the eye should read as more present than it does without makeup.

Cut Crease

The cut crease is an architectural eye technique. A sharp demarcation is drawn or pressed between the lid colour and the crease, creating a visible division that reads as structure from a distance.

Tightlining

Tightlining is the dark art of eye makeup. Done at all, it changes the look. Done well, no one can find what changed. The product goes inside the upper waterline — between the lash roots — so that the lash line appears thicker.
