Dermal undermining (scarification) of active rhytids and scars: enhancing the results of CO(2) laser skin resurfacing.
Active and passive rhytids develop as part of the aging process. Active rhytids become more prominent with facial animation. Efficacy of CO(2) laser resurfacing for active rhytids is enhanced by scarifying beneath the active rhytid before resurfacing. Scarification can be performed with a sterile hypodermic needle.
