    Laser Resurfacing


    What is a Laser?

    Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The laser beam can gently vaporize and/or ablate skin tissue to improve wrinkles, scars and blemishes, seal blood vessels or cut skin tissue. The laser has the unique ability to produce one specific color (wavelength) of light, which can be varied in its intensity and pulse duration. The newest laser systems have become remarkably precise and selective, allowing for wonderful results while being extremely safe.

    What is CO2 Skin Resurfacing?

    CO2 Laser resurfacing improves wrinkles, acne scars, and aging and sun-damaged skin, and is one of the most significant medical breakthrough in skin rejuvenation. Using a wand-like laser hand piece, undesired skin cells and wrinkles literally disappear in a puff of mist and are replaced by fresh skin cells. One of the laser's most significant advantages over traditional procedures such as a facelift is that treatment is relatively bloodless. The procedure also offers more control with respect to the depth of penetration of the skin's surface, therefore allowing for an increased degree of precision and safety.

    Who is Qualified to Perform Laser Surgery?

    Plastic Surgeons and Dermasurgeons have extensive experience with laser surgery and were among the first specialists to use lasers for skin renewal and treating a variety of skin disorders. Since results are technique-sensitive and entail an artistic component, it's important to select a surgeon with demonstrated laser expertise

    What Conditions Can Laser Resurfacing Treat?

    Laser resurfacing is performed in the surgeons office to help:

    • Erase fine lines and wrinkles of the face
    • Smooth and tighten eyelid skin
    • Improve crow's feet around the eyes
    • Soften pucker marks and frown lines
    • Remove brown spots and splotchy, uneven skin color
    • Improve and flatten scars
    • Repair smoker's lines
    • Improve skin tone and texture
    How Does the Erbium (Er) Laser Work?

    The high-powered erbium:YAG laser produces energy in a wavelength that gently penetrates the skin, is readily absorbed by water (a major component of tissue cells), and scatters the heat effects of the laser light. These unique properties allow dermatologic surgeons to remove thin layers of skin tissue with exquisite precision while minimizing damage to surrounding skin.The Er:YAG laser is commonly used for skin resurfacing in patients who have superficial to moderate facial wrinkles, mild surface scars or splotchy skin discolorations. Skin rejuvenation with the Er:YAG laser offers the advantages of reduced redness, decreased side effects and rapid healing compared to some other laser systems.

    How Do Non-Ablative Lasers Work?

    Unlike laser resurfacing technologies that heat and remove the top skin tissue, non-ablative or non-wounding lasers actually work beneath the surface skin layer. This novel approach appears to stimulate collagen growth and tighten underlying skin to improve skin tone and remove fine lines and mild to moderate skin damage. It offers the patient the benefits of few side effects and rapid healing with virtually no "downtime."

    What Can Be Expected During and After Treatment?

    Discomfort is usually minor during the procedure, and your dermatologic surgeon can discuss the administration of any pain medication prior to treatment. Following skin resurfacing, the treated areas usually are kept moist with ointment or surgical bandages for the first few days. The skin is typically red or pink and may be covered with a fine crust. The treated sites must be protected from sunlight after the procedure. Once healing is completed, sun block lotion should be applied. In some cases, a pink surface color may remain for several days to several months. Make-up can be worn after about 7-14 days.

    Are There Side Effects or Complications?

    Each year thousands of laser resurfacing procedures are performed successfully. Significant complications are rare, and the risk of scarring is low. Some patients may be at risk for varying degrees of pigmentation loss, particularly with the CO2 laser. Common minor side effects may include crusting, mild swelling, redness or brown discoloration at the treatment sites. These are usually minimized by surgical techniques and pre- and post-operative regimens.
    We encourage the use of Dermacia MD Lycogel® Camouflage products to help with healing and to minimize post treatment redness
    What Are the Limitations of Laser Resurfacing?

    Laser resurfacing is not a substitute for a facelift, nor can the procedure eliminate excessive skin or jowls. However, by tightening loose skin, laser resurfacing can improve certain folds and creases. Laser resurfacing offers an alternative to traditional resurfacing methods like dermabrasion, and can also work well in conjunction with or as an additional treatment to other cosmetic skin procedures such as chemical peels, blepharoplasty (eyelid) surgery and liposuction of the face and neck.
