Laser resurfacing is indicated in patients who have sun damaged, wrinkled appearance to the skin sometimes associated with uneven skin tones and/or large pores. Acne scarring, surgical or traumatic scars and stretch marks can all be softened with laser resurfacing.
History of Laser Resurfacing
Laser resurfacing of the skin can be done in several ways. The older C02 lasers delivered a beam of laser energy that covered the entire surface of the skin. Healing took place slowly and while the heat of this laser did tighten the skin, it did so with late complications of permanently lightening the skin color such that there was a line of demarcation where the laser treatment ended. Several years ago, the concept of a fractional approach was introduced. In Fractional Laser Resurfacing, the laser is applied in very small channels leaving a fair percentage of the skin untreated such that healing can take place more rapidly. There are two different types of fractional lasers. Non-ablative fractional lasers such as the Fraxel® and Affirm® (the one we have) use wavelengths of light that do not remove this column of skin. The energy causes a micro-channel of injury that, as it heals, causes new collagen to grow improving the texture of the skin. The non-ablative lasers work slowly and more subtlety and require multiple treatments due to the small percentage of skin surface that can be lasered in each treatment session. In contrast to non-ablative technology, both C02 and Erbium lasers can be delivered in a fractional approach. Both of these wavelengths actually remove the column of skin exposed leaving a proportion of the skin untreated to allow for faster healing. The C02 wavelength has characteristics that for every amount of skin column that is removed, about the same amount of skin is heated and injured. This injury causes the tightening effect but also has the deleterious side effects seen in the old C02 lasers: namely persistent redness and loss of skin color. Erbium (Sciton Profractional®) also removes this micro-channel of skin, but does so without the attendant heat. This laser can be adjusted to add the heat of a C02 laser or mimic the wavelength characteristics of the Pearl® laser. We can adjust the level of heat for each area of the face. We may use some heat to treat acne scars or tighten eyelid skin. We can also remove all the heat to remove wrinkles around the mouth or treat off of the face in the neck or hands.
This Sciton Profractional® laser is truly customizable for each patient’s unique requirements of effect and tolerance of downtime. Like the other fractional lasers, repeat treatments are additive to the overall effect. Usually 2-3 treatments will suffice.
The Affirm® laser requires no anesthesia other than the cold air blowing on the face through the handpiece. Most patients treated with the Affirm® laser can return to their prior activities the very next day.
Sciton Profractional® laser patients require some type of topical cream anesthetic applied 40 minutes before the procedure. Depending of the depth of the laser treatment, other types of local anesthesia including local nerve blocks or tumescent infiltration of dilute local anesthetics under the skin may be necessary for a comfortable treatment. The down time of this laser is completely adjustable to the patient’s needs. We usually combine a MicroLaserPeel® in which the superficial layer of the skin is removed with the fractional treatment done in the areas of the face and neck where wrinkle removal and skin discoloration need to be addressed. The skin after the Profractional® treatment may ooze for a few hours then appear like a moderate sunburn with some swelling of the treated area. Healing can be from 2-3 days to 7-8 days depending of depth and percentage of skin that is treated. Repeat treatments can be done in a few weeks. Usually 2-3 treatments are required for maximal effect but results are seen in just one treatment.
Sciton Profractional® laser treatments often times are combined with the Affirm® laser where one aggressive Profractional® laser is done first, then a series of Affirm® laser treatments are done spaced out over many months to keep the ongoing new collagen forming over a longer period of time and enhancing the overall result. Dermal fillers such as Resylane®, Juvederm® or Radiesse® or neurotoxins such as Botox® or Dysport®can be added to the treatment regimen to enhance the overall result by filling folds and minimizing movement wrinkles. We will also sometimes recommend BBL® intense pulsed light treatments for brown or red color removal after the Profractional® laser has healed. Combinations of BBL® with MicroLaserPeel are popular short recovery (1-2 days) procedures done in the Skin Spa by Salzman.
