FaceDescription: Two types of lasers exist: ablative and non-ablative.

Ablative lasers remove and resurface the skin, with excellent results, but require significant downtime to recover from pain and side-effects. Non-ablative lasers pass light through the skin without removing it; multiple treatments are required for good results but little downtime or discomfort exist.

Laser hair removal is most effective on dark-haired, fair-skinned people. Underarms and face respond best to treatment.

How it's done: Light is directed at the hair shaft, destroying it and preventing new growth. You will need several treatments to target hair in varying stages of the growth cycle.

Complications: Risks include temporary skin sensitivity, redness and skin discolouration.

Recovery: Two days.

Cost: $200 to $2,000 per treatment, depending on the size of the area being treated.
