The RHA Collection of facial fillers introduces a 4th dimension to facial aesthetics. This new facial filler which restores volume and reduces wrinkles includes the new added feature of adapting to the individual facial dynamics of each patient.
This new product describes the fourth dimension this way. The first aspect of hyaluronic acid fillers addressed wrinkles and folds at rest, where the next dimension was addressed by restoring volume at rest. The third dimension of fillers addressed static expressions. With its new technology, RHA is designed to adapt its effects to facial dynamics. This new technology, Preserved Network Technology, preserves the HA chain length, which more closely resemble your natural HA, presenting a more natural effect at both rest and in motion. The result is a dermal filler with a unique combination of stretch and strength that makes it resilient like your natural, youthful HA.
RHA has a proven clinical effectiveness of up to 15 months.
