Canfield's VISIA Complexion Analysis System provided standardized conditions that were crucial for the comparison of treatment results using a NIR 1064-nm neodymium: YAG laser in Asians. The original research, published by Dr. Yohei Tanaka of the Shinshu University School of Medicine, tracked the results in 50 patients over a period of 90 days to evaluate the effect on pores, skin texture and wrinkles. VISIA's precise imaging system and analytical software were critical elements in the evaluation.
