Maximum benefit is usually achieved with an average of 3 to 5 treatment sessions spaced about 2 to 4 weeks apart.
Wear sunscreen of SPF 30 or higher, avoid direct sun exposure for at least 3 months after your last treatment, and wear a wide-brimmed hat when you're in the sun.
During the first 24 hours after a treatment, your skin may feel as though it is sunburned, and it will appear pink or red. You can wear make-up to reduce the sunburned appearance. Your skin will naturally bronze over the next week or two, and as you continue treatment, the sunburned-to-bronzed appearance will repeat. As with a sunburn, your skin will flake and exfoliate normally. Use a moisturizer to reduce the appearance of dry flakes.
