There is actually only 1 filler that is designed specially for the tear trough and that is the Teosyal Redensity 2 from Teoxane Labs of Switzerland.
Usually many patients have accompanying dark eye circles at the tear troughs , therefore Teoxane invented this winning combination of premium Swiss hyaluronic acid that is a lightweight gel, semi-crosslinked, slightly-hygroscopic , spreads easily and mixed with 7 amino acids, 3 anti-oxidants (glutathione, N-acetylcysteine, alpha-lipoic acid), 2 minerals (zinc and copper) and 1 vitamin (B6).
Lightweight and semi-cross linked hyaluronic gel means that it doesn’t cause much mechanical pressure on surrounding tissues, as the tear trough area is a delicate area.
Slight hygroscopy means very minimal swelling which is great for treating the undereye area. Spreading easily also means the filler can be easily massaged to spread throughout the dark circles and tear trough , allowing for a homogenous diffusion and integration.
The patented complex of the amino acids, anti-oxidants , minerals and vitamin also makes the skin cells stronger and firmer and reduce dark eye circles.
It is little wonder that this Redensity 2 (I code named it the Panda Eyes filler) is so popular worldwide that even doctors who usually use other brands of hyaluronic acid will specifically buy this filler from Teoxane labs to use for the tear trough and dark eye circles.
Therefore , technically, there is only one specially designed filler for tear trough and dark eye circles treatment.
