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).
Nasolabial folds are deep wrinkles that form on both cheeks next to the nose. They start as shallow shadows and gradually deepen. We have summarized how the filling method differs from the lifting method, and ways to prevent them in daily life.
How do nasolabial folds deepen?
Skin aging begins in the mid-20s, and from the 30s and 40s, collagen decreases, leading to a loss of volume and elasticity. During this process, nasolabial folds deepen, extending from the side of the nostrils to the sides of the lips.
It is known that collagen decreases by about 1% each year after the age of 20, so a decrease in elasticity is a natural change.
Filling method vs. Lifting method
Nasolabial fold procedures are broadly divided into methods that replenish volume and methods that lift elasticity.
| Approach | Method | Characteristics |
|---|---|---|
| Filling | Volume replenishment in sunken areas | Tends to show immediate changes |
| Lifting | Induces collagen regeneration with heat | Improves elasticity over time |
Filling method
Filler is a procedure that fills sunken areas to refine volume and lines, and is used for deep nasolabial folds. The amount is determined by the depth of the indentation, and it is important to inject precisely at the appropriate depth, as excessive injection can lead to inflammation.
Ask which method is right for my nasolabial folds
Lifting method
The ultrasound method, represented by Ultherapy PRIME, works by creating heat coagulation points at a certain depth within the skin to induce collagen regeneration and tighten the skin.
- Used for overall areas such as around the eyes, glabella, mouth, nasolabial folds, and double chin
- Expects improved elasticity as sagging skin is tightened
- Results may vary by individual
Since various methods may be used in combination, it is recommended to consult and choose based on your skin type and preferences.
Prevention methods in daily life
Habits that prevent existing wrinkles from deepening are also important.
- Lie on your back instead of sleeping on your stomach or side
- Reduce habits of resting your chin on your hand or pouting
- Avoid frowning frequently
- Exercise the muscles around your mouth by pronouncing "a-e-i-o-u" or puffing out your cheeks
- Quit smoking to reduce skin aging and repetitive use around the mouth
- Maintain moisture around the mouth with hydration and nourishing creams
- Manage to prevent rapid volume loss due to excessive dieting
Conclusion
For nasolabial folds, what is right between filling and lifting varies from person to person, and results may differ individually. While practicing preventive habits together, please consult to find the method suitable for your condition.
