- Makeup usually possible next day
Rejuran I is often chosen by patients who want gradual, natural rejuvenation and improved skin quality.
Which Treatment Is Better for Under-Eye Hollows?
For mild hollows and early aging signs, Korean practitioners often recommend under-eye filler first due to its simplicity and minimal downtime.
Rejuran I is preferred when:
- Skin quality improvement is the main goal
- Fine lines or thin skin need gradual restoration
- Patients want subtle, natural rejuvenation
Many Seoul clinics combine:
- Under-eye filler for immediate volume and contour correction

This combination allows both instant results and lasting rejuvenation.

This approach balances immediate correction with gradual, long-term skin improvement.
