What Exactly Is the Epicanthal Fold?

It is a normal crescent of skin over the inner eye corner that can visually shorten the eye and pull a double fold downward at the front.

The epicanthal fold is a small web of skin running from the upper lid down across the inner corner of the eye. It is extremely common in East Asian faces and is a normal anatomical feature, not a flaw. Its practical relevance appears when planning any eyelid procedure.

How one small fold changes the whole impression

By covering part of the pink caruncle at the inner corner, the fold makes the visible eye shorter and the gap between the eyes look wider. It also anchors the front of any double eyelid line, which is why crease plans must negotiate with it rather than ignore it.

The fold ranges from barely visible to prominent, and its tension differs by individual, so its impact on your look is not uniform. If you wonder how much yours matters, a consultation with a specialist can show how the inner corner and a potential crease would interact.
