A Study of the Efficacy of Erbium:YAG 2940nm in Combination With 1064nm Laser on Facial Rejuvenation

The 1064 nm laser can penetrate deep into the skin to explode pigment particles, destroy blood vessels and heat the dermal collagen by targeting melanin and haemoglobin.(1) Frac3®: 30-35 J/cm2, 1.6 ms pulse width, 4mm spot size, unilaterally accumulated 2000 shots; and (2) PIANO®: 160 J/cm2, 5s pulse width, spot size 9mm, unilaterally accumulated 20000 shots, to increase and maintain facial skin temperature to 39-40oC.

Er:YAG 2940nm have been considered as a good treatment of facial aging, especially in wrinkles.(1) Smooth®: 9-10 J/cm2, 7mm spot size, which is sequentially delivered to upper and lower labial mucosa and buccal mucosa to unilaterally accumulate 5000 shots; (2) SupErficial™: 0.5-1.0 J/cm2, 7mm spot size, a single pass
