Laser resurfacing - What can go wrong?

The complications of laser resurfacing are essentially the same as those of chemical peels and dermabrasion, says Patrick Hudson, a New York based plastic surgeon. Here's a brief review of some of the problems that may arise.

Sensation of heat:
during the first week, many patients complain of intense heat. This is less common when occlusive dressings are used.

Scarring:
severe burns resulting in scarring are always a risk.

Infection:
(bacteria) and yeast infection may be more common when occlusive dressings are used. Serious infection can increase the depth of the burn and lead to scarring.

Hyperpigmentation:
increased pigmentation (darkening) may occur in about one in four patients. In many cases, it is temporary, but can be permanent. To minimise the risk of pigmentation, surgeons recommend a sunscreen with a SPF of at least 16, and avoiding sun exposure.

Hypopigmentation:
a decrease in pigment in the skin is seen in about one in 20 patients and may be permanent.

Herpes:
it is possible to develop herpes infections in the treated area during the early recovery phase. Some surgeons recommend the use of prophylactic anti-herptic medicine.

Breakouts:
Some patients experience a mild eruption of small pimples in the early recovery period. Others may develop "whitehead? or milia which are easily treated.

Tooth injury:
the teeth must be protected or the laser can damage the enamel.

Eye injury:
the eyes must be protected with a shield to prevent damage such as corneal ulcers.

Ectropion:
when the eyelid is treated with laser, an excess tightening of the skin may occur. This may result in a pulling down of the lower lid, called an ectropion. This is more common in patients who have laxity of the eyelid before surgery

Lagophthalmos:
although it's rarely permanent, tightening of upper eyelid skin may prevent complete closure of the eyes.
