No Filler! — Collagen Volumizing InjectionCOVA: No-Filler Tear Trough
COVA: No-Filler Tear Trough
COVA Collagen Volume Needle is a PDO-based treatment that stimulates your body’s natural collagen production, restoring volume that lasts. Unlike traditional fillers, this innovative technique not only fills hollow areas but also triggers new collagen growth — delivering immediate, natural-looking results. Because COVA is less likely to migrate than fillers, its effects remain stable and long-lasting. With your own collagen supporting the skin from within, you can enjoy lasting results without the risk of unwanted shape distortion. *VAT not included

Collagen Volume Thread Injection – What is COVA?
Traditional fillers add volume by injecting a gel-type substance beneath the skin.
COVA, however, works by stimulating skin regeneration and collagen production, allowing volume to build naturally over time.
As time passes, the skin gradually becomes fuller on its own — creating a more natural look and feel.
While fillers may sometimes shift or form lumps after injection,
COVA is absorbed evenly within the skin, reducing these concerns.
COVA is made of PDO (polydioxanone), a material that naturally dissolves in the body and is widely used in medical procedures.
Fillers can appear unnatural or carry a higher risk of overcorrection in delicate areas such as around the eyes or mouth.
COVA is suitable even for thin, sensitive skin, providing smoother and more natural results.
Side effects sometimes associated with fillers — such as vascular blockage or embolism — are not seen with COVA, making it a safer alternative.
Compared to Juvelook Volume and other collagen injections,
COVA offers added structural support, delivering stronger and more immediate volume improvement.
