The Rodan + Fields AMP MD micro-needle roller was designed as part of the Rodan + Fields Anti-Age regimen and was originally paired with the Rodan + Fields Anti-Age Night Renewing Serum which is carefully formulated to be safe when absorbed into the skin. Clinical trials showed an amazing 100% improvement in the overall appearance of the skin of those who participated in the study using the Anti-Age Night Renewing Serum with the micro-needle roller.
