YES! A few patients do notice their skin feeling tight immediately after the treatment as if the skin has been exposed to the sun or wind. You might experience a slight dryness of the skin depending upon your skin type. An effective moisturizer is applied after the treatment to prevent this drying of the skin. The skin might appear slightly red for the remainder of the day. Initially, you may feel a very mild scratching sensation as the diamond tip makes contact with the skin. As the treatments continue, this experience compares to a deep massage. Mild redness may occur for ½ an hour to one day depending on the aggressiveness of the program.
