Abstract

Abstract: To investigate the efficacy and safety of combined treatment with a serum comprising a micro‐diamond suspension and micro‐gold cage with a 1064 nm picosecond neodymium‐doped yttrium aluminum garnet (Nd:YAG) laser for facial skin rejuvenation. Topical serum was applied to the entire face and allowed to penetrate the skin and hair follicles for 20 min. Each participant was then treated with a 1064 nm picosecond Nd:YAG laser on the face. Photographs of each participant were taken at baseline, immediately after treatment, and 2 weeks after treatment using an imaging tool (Mark‐Vu®; PSI PLUS, Suwon, Republic of Korea). Global improvement scores by two blinded investigators and participants' satisfaction scores were also assessed. The melanin index (MI), transepidermal water loss (TEWL), and skin hydration were evaluated using a device. Parameters associated with skin rejuvenation were assessed using Mark‐Vu®. Adverse events were observed and reported by participants and physicians during the treatment and follow‐up visit. At week 2, 40% (4/10) of the participants showed more than moderate clinical improvement in the investigator's global improvement assessment. No significant differences were observed in the MI, TEWL, skin hydration level, or skin parameters of Mark‐Vu®. At week 2, 40% of the participants reported a high satisfaction score and minimal side effects. The novel topical facial serum comprising micro‐diamond suspension and micro‐gold cage is safe and effective when combined with laser treatment for facial rejuvenation.
