The light is changed into heat energy. The heat then destroys thin sections of skin, layer by layer. As the wounded area heals, new skin grows to replace the damaged skin that was removed during the laser treatment.
Some lasers only tighten the skin by heating it but do not destroy the skin.
Why It Is DoneLaser resurfacing may be used to remove or improve the look of:
- Superficial scars from acne, surgery, or trauma that are not growing or that are getting thicker.
- Color (pigment) changes or defects in the skin, such as liver spots, port-wine stains, or café-au-lait spots.
Ablative Laser ResurfacingWith advances in laser technology, it is now possible to significantly improve aged or sun-damaged skin. Ablative laser skin resurfacing is one of the most effective cosmetic procedures for improving aging skin. The procedure works by delivering an intense wavelength of light to the skin, which removes the outer layers of aged or sun damaged skin. In addition, the laser stimulates the underlying skin, resulting in collagen formation and an improvement in wrinkles. As the lasered skin heals following the procedure, new skin forms that is smoother and tighter.
Ablative lasers are used to treat:
- Fine to moderate wrinkles
- Liver spots or age spots
- Uneven skin tone
- Sun-damaged skin
- Acne or chickenpox scars
Fractional laser resurfacingFractional laser treatment is a non-invasive treatment that uses a device to deliver a laser beam divided into thousands of microscopic treatment zones that target a fraction of the skin at a time. This is analogous to a photographic image being enhanced or altered pixel by pixel. Fractional laser treatment has bridged the gap between the ablative and non-ablative laser techniques used to treat sun-damaged and aging skin. Whilst ablative laser treatments work mainly on the epidermis (surface skin cells) and non-ablative treatments work solely on dermal collagen (mid-layer of skin) only, fractional laser treatment works at both the epidermal and dermal layers of the skin.
Fractional laser treatment is used for the treatment of:
- Facial lines and wrinkles (rhytides)
- Sun damage
- Skin pigmentation associated with photoaging Surgical and acne scarring.
