What's the Best Laser for Skin Resurfacing?

I risk the disagreement of many of my colleagues who have and use fractional lasers in their practices, but I would be able to submit evidence that this is indeed a correct statement. First, I will state that there is nothing WRONG with fractional lasers or resurfacing--they do make nice changes in the skin and are generally appreciated by patients who have these procedures. BUT . . . laser surgeons who charge a lot, and promise even more, can risk the wrath of patients who feel their fractional laser results are not a good value for what they paid, or who required more healing time than "advertised."

I have taught laser surgery, including resurfacing, for over twenty years, nationally and internationally (Korea, Canada, Caribbean), and have performed thousands of laser cases in my practice. (I am in private practice,  do not have academic affiliation, publish sparingly, but have taught nearly a hundred laser courses and thousands of physicians of various specialties over these years). Now, just the facts, Ma'am.

Ablative CO2 laser resurfacing came first, gave great (dramatic) results, but fell somewhat out of favor as hypopigmentation (skin color lightening) occurred a year or so after treatment. Wrinkles, spots, and sun damage still gone, but line of demarcation where treatment stopped, and lighter skin color where treatment was done. Bummer!

Ablative Erbium-YAG laser resurfacing came next, but treated much more superficial layers, so skin healed faster, with less redness, but with less dramatic changes. If the doctor promoted this as "better than CO2" and charged as much, patients were unhappy, but not because the laser had a "problem" other than milder results. Bad doctor "marketing!"

By the time that third-generation combination CO2/Erbium-YAG lasers came along about ten years ago, the herd of dermatologists, plastic surgeons, and other laser doctors had moved on to the "non-ablative" lasers or therapies such as Thermage, N-lite, Cool-touch, Smoothbeam, Fotofacial, and many others. These all "worked" to varying degrees, but usually with very minimal results. Prices dropped, and so did most of the hype, and "the herd" of doctors that need the "latest and the greatest" moved on to Fractional lasers.

Fractional lasers started with Erbium wavelength lasers (old lasers in new boxes) with scanner handpieces re-purposed to treat the skin in tiny polka-dots. Bridges of intact skin were left untreated, which is said to promote faster healing and less down-time (partially true). Actually, less skin treated = less result, which required multiple treatments, which = more procedures, more healing and MORE cumulative downtime. Oh, and the total cost adds up to a tidy sum usually! The results are real, but with superficial layer and polka-dot treatment came mild results (sometimes with a "pebbly" texture from improperly-spaced polka-dots). More, give us more!

The next fractional lasers returned to CO2 wavelengths, which penetrate deeper, and still treated skin in tiny polka-dots. Fortunately, unless the energy was turned up too much, or the polka-dot density too tight, hypopigmentation changes were limited, and the results were indeed better. Still only in the fraction of the skin treated, still requiring more than one treatment for results that could approach that of well-performed third-generation combination CO2/Erbium-YAG ablative resurfacing (which very few doctors even had then, or have today), and still adding up to a tidy sum for only "fractional" results. BTW, it still takes a week to heal fractional laser treatments, and if you add up the time for multiple procedures, doctor's visits, and cost, HOW can this be "LESS DOWNTIME"?

So at the risk of being contrarian, I would submit that a properly-performed ablative dual-wavelength CO2/Erbium-YAG full-face laser resurfacing remains the BEST one-time laser resurfacing procedure available. With proper skin care, I routinely have patients healed in 7-10 days, and with minimal (truly) redness easily covered with standard make-up. The results are much more uniform than any fractional polka-dot treatment, multiple treatments are not necessary, and healing doesn't take any longer than most fractional treatments. Smoothness and outcomes are superior, and downtime is certainly less than any multiple-session protocols! I even purchased a second CO2/Erbium-YAG laser for parts--they are no longer available. But the marketplace delivers what the public (and their doctors) demand. I know from all the courses I have taught over the years, that many, if not most, of the doctors that use lasers don't even understand the basic laser biophysics of how laser energy interacts with tissues--they just want to know "what is the basic setting, where is the trigger, and how much can I charge?"

Enough said, my soapbox is sagging! Caveat emptor!

Fractional laser is an amazing and highly effective treatment in our office. We use the laser treatment to help with acne scars, large pores, fine wrinkles, tissue collagen loss, scars, sebaceous hyperplasia, active acne, and for brightening dark pigmentation. Although there are very strong fractional lasers such as CO2 laser, we use lighter treatments for corrective skincare and maintenance of results. Our Thulium fractional laser, clear and brilliant laser, and Ultra Thulium laser are excellent options in our clinic. We also perform CO2 fractional and erbium depending on skin tone and tolerance for downtime. Patients do have to use a Melarase cream before and after treatment to help further reduce pigmentation after laser. Dark spots can improve with these treatments. I recommend fractional laser for incisional scars as well, especially after plastic surgery.

Fraxel and/or CO2 are best for resurfacing, but Erbium is a good alternative. I always combine lasers with microneedling/PRP for more robust outcomes. For skin tightening, I recommend a combination of Ultherapy with RF treatments and Sculptra for skin tightening. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer

The laser we recommend for optimal skin resurfacing is the Profractional laser by Sciton, which is an Erbium YAG laser device. This laser works by breaking down the beam to smaller “baby beams,” which allow healthy tissue to repopulate more quickly and therefore resurface your skin.  A short and long pulse width allows the settings to be adjusted to be more or less aggressive, depending on your skin type and what concerns we are addressing. Your skin texture can go from “burlap to silk,” and collagen can be stimulated as well.  

There is no one "best" laser for skin resurfacing. In my practice, I utilize several different lasers depending on the patient, skin type, area of concern, goals of treatment, and potential available down time. I most commonly utilize a fractional CO2 laser or an Erbium:Yag laser for skin resurfacing. I find that I am able to get very aggressive results with minimal down time using these devices. There are MANY different types and name brands of lasers out there. Be sure to find a doctor that you trust and can show you legitimate before and after results of patients who have been treated with the laser that they recommend so you can understand the types of changes that are possible and expected.Best,

I often get asked what the best laser is for skin resurfacing.  Not all lasers are the same.  There are different modalities that exist, such as CO2 lasers, erbium lasers, etc.  However, most lasers do work to achieve similar results.  For instance, some lasers may focus on pigment, some on redness, and some on improving texture and tone.  Some lasers are can be aggressive while others can be almost as mild as a peel.  Although your dermatologist and/or favorite Medspa may carry two different brands of lasers, each of the lasers may be appropriate for you, depending on the issues you desire to address.  Consult with knowledgeable provider who will tell you whether or not you are a good candidate for laser resurfacing.
