The word laser is an acronym for light amplification by stimulated emission of radiation. A laser is a single wavelength source of high-energy light that can be accurately focused to transmit that light on to a very small area. The use of lasers in skin rejuvenation has given patients many options for softening the signs of aging without “going under the knife” or undergoing facelift procedures. Lasers can also be used to improve imperfections in the skin due to other medical factors besides aging.
There are basically two different types of lasers: ablative and non-ablative. Ablative lasers vaporize the top layers of damaged skin. Ablative laser procedures generally produce significant effects with just one treatment. Because the top layer of skin is destroyed, down time is necessary for ablative laser procedures. Non-ablative lasers work deeper in the skin without removing or otherwise damaging the top layers of the skin. They also stimulate new collagen growth. The lack of down time required for non-ablative laser procedures offers significant benefits to patients. However, non-ablative laser procedures usually require multiple treatments to have significant effects.
The use of lasers in facial cosmetic procedures has revolutionized skin rejuvenation. It has also greatly increased the options for patients who desire to look younger or to improve their appearance but are not willing to undergo plastic surgery. Lasers are currently used for the following cosmetic treatments:
• Fine lines and wrinkles
• Skin tightening
• Pigmented lesions (sun spots, age spots, melasma and other forms of
hyperpigmentation)
• Removal of precancerous lesions such as actinic keratoses
• Vascular lesions (broken blood vessels on the face, veins on the legs, spider nevi,
hemangiomas and birth marks such as port wine stains)
• Tattoo removal
• Acne and acne scar removal
• Hair removal
Different types of lasers are better suited for treating different types of conditions. The Fraxel or other fractionated lasers may be the best for treating wrinkles around the eyes. The CO2 or Er:YAG are well-suited for treating acne scars. IPL may be the best to treat vascular lesions and to improve the skin’s texture and color. The good news is that so many different types of treatments are available. If you are interested in laser skin rejuvenation procedures, consult a licensed, experienced dermatologist or plastic surgeon in your area.
