The first effect of tightening, smoothing and brightening of the skin may be visible immediately after the treatment. Over the following months, the skin's appearance - its hydration and texture - should gradually improve due to increased fibroblast activity and the body's process of producing new hyaluronic acid, collagen and elastin. It is important to remember that every body is different and effects may vary due to individual conditions. Clinical studies have shown as much as 224% increase in hyaluronic acid after a full treatment series.
