This is a guide to filler compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).

The face is often the first place to show the effects of time, and among facial features, the under-eye area is where changes are felt most quickly. Many people wish to address under-eye hollowness through collagen regeneration, so we will summarize common discussions from the consultation room.
Why do the under-eyes hollow quickly?
The under-eye area is a part of the face that is relatively quick to show the effects of aging.
- It is an area with frequent facial movements and thin skin.
- When it hollows, it can create shadows and easily make one look tired.
- Changes accumulate along with a decrease in collagen.
Recently, there has been an increasing trend for even younger age groups to consider early management.
Characteristics of Collagen Regeneration Methods
Collagen regeneration methods utilize PLLA ingredients to help collagen gradually fill in hollow areas over time.
- Unlike fillers, it provides gradual rather than immediate changes.
- As changes appear slowly, a natural progression can be expected.
- It can be used not only for the under-eyes but also for nasolabial folds, cheeks, and jawline.
It is good to be aware that it takes some time for you to feel the changes.
Points to Consider When Proceeding
This method promotes collagen production rather than filling with artificial foreign substances, so it settles gradually.
- It is important to predict the process of change in advance and plan meticulously.
- Design based on extensive experience influences the results.
- The under-eye area is particularly delicate, requiring a cautious approach.
Through a consultation with Dr. Choi Byeong-geun, please confirm the appropriate approach for your condition. If you are curious about under-eye management, please inquire via chat.
In Summary
Under-eye collagen regeneration is a method considered by those who desire natural changes. As it settles gradually, the process of predicting and planning the changes is important. If you have any questions, please feel free to inquire via chat consultation.
