Resurfacing lasers are good for tightening pores. The ablative options include the fractional CO2 and Erbium:Yag, the non-ablative options include the Thulium, Erbium:Glass and the long pulsed ND:Yag lasers.
Which combination and frequency to treat them depend on your individual condition, but usually the non-ablative options are repeated no earlier than every 2 weeks, and the ablative options no earlier than 4 weeks.
