A consultation with a qualified physician can help determine if you are an appropriate candidate for laser skin resurfacing, and which laser is best suited to your skin type and/or condition. There is no one-size-fits-all laser, and the latest laser is not necessarily the greatest for you.
Make sure the physician you choose has your complete medical history and a list of any medications, supplements or herbal products that you take. If you have a history of cold sores, fever blisters, herpes, chicken pox, shingles or other viral infections, tell your surgeon. These viruses lie dormant in your body between outbreaks and can flare up after laser skin resurfacing.
