VISIA is an in-depth analysis of your individual facial characteristics. The VISIA scans your skin, looking at its strengths and weaknesses. VISIA scans measure your skin pigmentation, pore size, and porphyrins (evidence of bacteria lodged in pores). It also scans UV spots, sun damage, texture, and wrinkles. Developed by Canfield Imaging Systems, this multispectral imaging system provides some of the most comprehensive information on skin health today. In addition to identifying areas requiring treatment, the VISIA skin analysis can track treatments to determine whether those treatments are having the desired effect at the cellular level.
