is this for me
Who it’s for
Even if none of these describes you, we will look again at the consultation.
- How deep the tear trough hollow is, any tendency to puffiness, and whether Renefil’s combined HA and PN formula suits the area
- Containing PN does not make Renefil the same as Rejuran. Its HA–PN formulation and product properties require a separate plan. Under-eye darkness may involve hollows, protruding fat, pigmentation or skin quality. Product instructions, eyelid function and previous treatments guide suitability. Inclusion in this menu does not mean every product is injected directly under the eyes.
Suitability requires an examination. Skin thickness, health and previous procedures may make a different approach more appropriate.

the qd standard
The same treatment, never the same plan.
Rather than a fashionable name or a fixed package, we weigh the structure found at examination, safety, recovery and the limits within one plan.
- DIAGNOSIS FIRST
Cause before name
We first separate out the tissue and the function behind your concern.
- LESS, PRECISE
Only as much as needed
Rather than an excessive change, we plan the smallest scope with a clear role.
- HONEST LIMIT
The limits, explained too
We explain the change you can expect, the alternatives, individual differences and the risks.

Look at the examination and the plan rather than the treatment name. First, what the clinic checks before deciding — at QD Clinic in Gangnam, Seoul, the first thing we look at for this treatment is “How deep the tear trough hollow is, any tendency to puffiness, and whether Renefil’s combined HA and PN formula suits the area”. Second, whether it explains why it recommends that scope and method, compared with the alternatives. Third, whether it reviews your progress with you when results are expected. Our doctor goes through these three points at consultation before the treatment is decided.
