Palo Alto Laser and Skin Care, your safety and comfort are always our top priority. Discomfort varies person to person and laser to laser. To make your treatment more comfortable, we use topical numbing prior to any laser treatments with any discomfort. To make your experience even better we offer the latest in comfort therapy-the Pro-Nox. The patient administered analgesia system is safe (it is used during labor) and clears out of your body within minutes, so there is no need for anybody to pick you up or drive you.
