There are many different types of lasers, some with significantly different properties, and within each type of laser there are multiple brand names that may have slightly different bells and whistles to go with it. It's no wonder that it can be difficult as a consumer to sort them all out, and that's why this is such a great question. Often times, physicians push one laser as the best, because that is the one they have.A great analogy is pants: there are slacks, jeans, suits, even shorts, and within each of those there are an abundance of brands that make them. You are usually looking for a specific kind of pant, usually in a certain color, and you have a unique size and cut that is best for you. Once you're at that point the pockets or buttons or pleats may be slightly different, but at least you are in the right category. The best laser question you can answer is, what are you looking to get out of your laser: wrinkles, pigment, scarring, redness, all of the above? As an example: for wrinkles, you can do fully ablative, fractionally ablative (CO2 and erbium) or fractionally non ablative lasers. Your downtime is going to vary between each one, and your downtime is going to be directly proportional to your results - more downtime, more results. Your physician should have this discussion with you first and foremost to determine your goals, then start to discuss multiple options with varying downtime and results. Most respectable laser practices will have multiple lasers and multiple options, ask them how many options they have for your particular goal. Seek out a Dermatologic surgeon, oculoplastic surgeon, plastic surgeon or facial plastic surgeon who is board certified and fellowship trained in one of these core four cosmetic specialties.
