Ultherapy Prime is famous for having almost no downtime, which makes patients curious about what does happen in the months after. KATE CLINIC in Hongdae lays out the timeline.
Day 0-2: subtle and social
Skin may look faintly flushed for a few hours and feel tender when pressed. Makeup is fine the same day; most patients go straight back to their schedule. Saunas and hard workouts wait 48 hours.

Week 1-2: the quiet phase
Any tenderness fades. Some patients feel occasional tingling, a normal sign of the healing response, not a problem. The early tightness from the day of treatment may seem to soften; this is expected, as the real remodeling has not yet peaked.
Month 1-3: where the result is built
New collagen forms progressively, and this is when jawline definition and cheek support become visible in photos. Most patients see the clearest difference around month two to three, often after they have returned home from Seoul.

After month 3: maintaining it
Results are typically enjoyed for around a year, gradually easing as aging continues. Many patients schedule a maintenance session annually. Duration and degree of change vary by individual.
One practical note for travelers
Because the effect matures after you fly home, KATE CLINIC offers photo-based follow-up for international patients. Consultations can be arranged through Clinic in Korea.
