In-fold, out-fold, and in-out fold are double eyelid styles defined by where the crease starts relative to the inner corner. In-fold starts inside the corner for a natural look, out-fold starts above it for a Westernized appearance, and in-out fold blends both for a tapered, defined shape.
- In-fold: The crease starts inside the inner corner, creating a subtle, natural Asian look.
- Out-fold: The crease begins above the inner corner, resulting in a bold, parallel Westernized appearance.
- In-out fold: A hybrid style starting narrowly at the corner and widening toward the outer edge.
- Settling time: Patients should expect 1 to 3 months for the new crease to fully settle.
Bookimed Expert Insight: Data from top Seoul clinics like JK Plastic Surgery Center and HERSHE shows that in-out folds are increasingly the standard for first-time surgeries. While out-folds achieve a high-glamour look, they carry higher asymmetry risks on uneven lids, making the hybrid in-out technique a safer, more versatile choice for most eye shapes.
Patient Consensus: Patients often recommend viewing surgeon portfolios filtered specifically by fold type before deciding. Many find that while out-folds make eyes appear significantly wider, the in-out fold remains the most reliable option for achieving a balanced, tapered result.
