Monophasic Hyaluronic Acid
Monophasic fillers consist of a smooth, homogeneous gel formed by cross-linked hyaluronic acid chains. This uniform structure resembles jelly and allows for smooth injection and even distribution within the tissue. The result is a natural feel and appearance, minimizing the risk of lumps or irregularities.
Biphasic Hyaluronic Acid
Biphasic fillers are composed of cross-linked particles suspended in a non-cross-linked liquid. This combination creates a unique texture that can be likened to sago. The dual structure offers both volume and flexibility, making these fillers versatile for various aesthetic treatments.
