Sun takes its toll on the skin, but the effects need not be permanent

During ablative laser resurfacing, an intense beam of light energy destroys the outer layer of skin (epidermis). At the same time, the laser heats the underlying skin (dermis), which causes collagen fibers to shrink. As the wound heals, new skin forms that’s smoother and tighter. Ablative laser resurfacing typically takes 30 minutes to two hours, depending on the technique used and the size of the area treated.

After ablative laser resurfacing, the treated skin will be raw, swollen and itchy. The yellowish liquid that oozes from treated areas may form crusts. A thick ointment may be applied to the treated skin and covered with an airtight and watertight dressing.

Nonablative lasers damage collagen beneath the skin and stimulate the growth of new collagen, tightening underlying skin and improving skin tone and appearance. No skin is removed.

Nonablative laser resurfacing typically takes less than an hour, depending on the technique used and size of the area treated. To achieve desired results, a series of treatments is typically scheduled over the course of weeks or months. Results after nonablative lasering tend to be gradual and progressive, rather than immediate and dramatic. You’re more likely to notice improvements in skin texture and pigment than wrinkles.

Downfalls/possible risks: Ablative laser resurfacing can cause various side effects, including itching, swelling, stinging and redness for about two weeks. The degree of redness is related to the depth of the resurfacing and can be intense and last for several months. Bacterial, viral or fungal infection may also result, the most common being a flare-up of the herpes virus.

Nonablative lasering also can cause side effects, including infection, flare-up of the herpes virus, hyperpigmentation, mild swelling and redness.

Cost: $500 to $5,000, depending on the type of laser treatment and how many treatments are needed.
