Dr. Lam offers two types of lasers: non-ablative (no-downtime) and ablative (removal of old skin and a week or so of downtime). His non-ablative laser, KTP and Nd:YAG, helps with rosacea, redness, uneven color, pores, and mild texture problems. Dr. Lam uses two ablative lasers: the Cortex and the 2940 nm. He finds the Cortex to be ideal for lighter problem of skin aging; whereas he uses the 2940 nm primarily for deeper wrinkle problems, especially those around the mouth.
