I know someone asked about using copper peptides with the LightStim. I found this on NCN Skincare site. If you’re new to Copper Peptide, use your DPL for 2 months before you apply CP first. Never use a product that contains an acid prior to your LED treatment. There is a lot of info. on this site if anyone is interested in reading it. http://ncnskincare.com/blog/category/matrixyl-3000
