Skin booster and RF lectures at ASLS Vietnam Hanoi 2025
His lectures covered HA and PLLA combinations to stimulate collagen from the dermis to the ligaments, and 6.78 MHz monopolar RF.
Dr. Chang-Hwan Cho spoke at the International Congress of ASLS & VSAPS in Hanoi on July 5–6, 2025. He presented approaches to skin rejuvenation using high- and low-molecular-weight HA complexes and PLLA–PN complexes, including three-dimensional collagen stimulation from the dermis to the ligaments. He also discussed 5 cm², 6.78 MHz impedance-matched monopolar RF with six pulses and seven cooling cycles. The talks were well received by Korean and international attendees.
