Laser is actually an acronym standing for: Light Amplification by Stimulated Emission of Radiation. Using selected beams of light, many skin conditions can be treated and cosmetic enhancements performed in a selected fashion. Dr. McGillis has worked with lasers long before they became widely available and has taught other physicians how to use them. She has assisted in starting laser centers in Singapore and advising many others. Lasers are used to treat leg veins, tattoos, wrinkles, hair removal and for removing brown spots to name a few.
