Clinical Experience of Spectra-Peel (Soft-Peel) on Japanese Patients
American Society for Laser Medicine and Surgery 2004 Abstract
Takahiro Fujimoto MD, Avenue Roppongi Clinic Tokyo Japan
Objective
The purpose of this clinical study was to determine the effectiveness of non-ablative facial rejuvenation process using Dual pulsed (Q-switched and 300 us pulsed) YAG laser and carbon based lotion as laser activating chromosphere, focusing on skin texture improvement and pore size reduction.
Materials and Methods
58 human subjects ,skin types ⅡtoⅣ, Ages 30’s to 50’s with enlarged facial pores were treated with three to five laser sessions at our clinic.
Cosmetic skin rejuvenation was accomplished using a wavelength of 1064 nm, fluence of 1.8 to 2.3J/cm2, a pulse duration of 300um (long pulse) and 5nm (Q-switch), a pulse repetition rate of 10 Hz and fixed beam size of 7mm.
The treatment involved applying carbon suspended lotion to the skin surface and irradiating Nd:YAG laser full face, first with long pulse mode followed by Q-switch mode.
Treatment sites were evaluated regarding skin texture, pore size, fine wrinkles and spotty pigments at base line.
Results
At 8 months follow-up the investigators reported improvement in skin texture, pore size, fine wrinkles and spotty pigments compared to base line.

Conclusions
Topical carbon suspension assisted Nd:YAG laser treatment combining long pulse and Q-switch mode offers a safe cosmetic method of improving skin texture, especially pore size reduction.
