When searching for nasolabial fold filler prices, many people are often surprised by the significant price differences between clinics.
Before comparing prices, there's something you should check first. You need to consider whether filler is the right choice for your current nasolabial fold condition, or if COVA (PDO volume thread) might be a more suitable alternative.

Why Do Nasolabial Folds Appear?
Nasolabial folds are structural changes where the fat and collagen beneath the skin decrease, causing grooves to form between the cheeks and mouth area.
Repeated facial muscle movements, loss of cheek volume, and decreased skin elasticity are the main causes. For this reason, treatments that replenish volume are closer to a fundamental solution than approaches that only address the surface.

The Principles and Limitations of Fillers
Nasolabial fold filler involves directly injecting hyaluronic acid (HA) into the nasolabial lines to fill the sunken areas.
The advantage is immediate volume restoration visible right after the procedure. The duration typically ranges from 6 to 12 months, varying depending on the amount injected and individual metabolic rates.
A drawback is the potential for migration. HA fillers can shift in unintended directions or clump together due to pressure or massage after injection. Depending on the product, some individuals may experience a foreign body sensation or an artificial appearance.

The Principle of COVA
COVA is a procedure that involves injecting a component called PDO (Polydioxanone) into the dermal layer. It is also known as a volume thread.
The PDO component gradually absorbs within the skin, stimulating collagen production, and ultimately forming volume with your own collagen. Since the injected component is fixed in the tissue, there is no risk of migration like with fillers.
Immediate effects appear more slowly than with fillers, but because it's a natural plumping process, there's no artificial sensation.

When treated with a sufficient amount, the duration can last up to 1 year. If the initial treatment amount was not sufficient, it can be supplemented with an additional procedure after 2 weeks.
Filler vs. COVA: Which is Right for Which Situation?
Fillers are suitable when immediate correction is needed. Since volume is visible on the day of the procedure, it's chosen when there's an important event or when rapid changes are desired.
If you are concerned about migration or a foreign body sensation, COVA is advantageous. PDO is fixed in the tissue, so there is no migration, and the process of converting to collagen is natural.
From a cost-effectiveness perspective, even if the initial nasolabial fold filler price seems low, the cumulative cost will differ if repeated treatments are needed every 6-12 months. COVA, when administered in a sufficient amount, can last for 1 year.

If you have already received repeated filler treatments but feel the results are unnatural, or have experienced migration or clumping, COVA becomes a realistic alternative.

Bruising or swelling may occur after the procedure but subsides within a few days. Since the procedure is performed after applying anesthetic cream, the pain is not severe.
Kkeut Clinic's Unique COVA Treatment Approach
Kkeut Clinic clearly explains the comparison with COVA even to those who initially search for nasolabial fold filler prices, right from the consultation stage.
We do not unconditionally recommend COVA. We comprehensively assess the depth of nasolabial folds, previous treatment history, and desired pace of change to determine and present whether filler or COVA is more suitable for your current condition.

Frequently Asked Questions
Q. How should I compare nasolabial fold filler prices and COVA prices?
A. Nasolabial fold filler prices vary depending on the amount injected and the product used. An accurate comparison involves considering the duration of effect and the frequency of repeat treatments, rather than just comparing initial costs. At Kkeut Clinic, we guide you through options tailored to your individual condition after a consultation.
Q. COVA is said to last longer than nasolabial fold filler; when do the treatment effects appear?
A. Unlike nasolabial fold filler, COVA does not provide immediate volume on the day of treatment. As PDO gradually converts into collagen, you will experience a natural plumping effect over several weeks to months. If the amount from the first treatment is not sufficient, Kkeut Clinic offers additional supplementation after 2 weeks.
Q. I've already had fillers; can I switch to COVA for my nasolabial folds?
A. Many choose COVA after their existing fillers have been absorbed. Even if you first learned about COVA while searching for nasolabial fold filler prices, the priority is to assess your current condition and determine the best course of action during a consultation at Kkeut Clinic.
