One session is recommended, with one or two a year thereafter. Firmness and contour tidy up over two to three months, because collagen builds while the heat points at different depths heal. It holds a long time, so the next session is scheduled after watching for two or three months.

The difference is using two kinds of RF together to heat the deep layer and the surface in one pass. One reaches the layer that supports the skin while the other concentrates near the surface, targeting two depths at once. Cooling in three stages to reduce the load on the surface is another feature.

It feels hot during the session, but cooling runs alongside to keep it at a tolerable level. Because cooling happens in three stages, little strain is left on the surface. There is no downtime and you can wear make-up the same day; just skip the sauna for a week until the heat has settled.
