After even a single treatment, your skin will be visibly refined, and polished. Your pore size will appear smaller and your skin should appear healthier and well-hydrated. Effects last up to 2-3 weeks. These treatments are good to do before a big event, as they will make the skin look renewed and fresh. If you are doing these treatments in a series, you should expect to do them about once every 4 weeks. These treatments are safe to do for any age or skin type.
