Which of the current ARTISTRY® serums is the best replacement for the Alpha Hydroxy Serum?

This depends on your skin concern.  To reduce open pores and for a more even-textured and refined skin we suggest ARTISTRY® Intensive Skincare Advanced Skin Refinisher.  As an anti-ageing treatment we suggest the Intensive Skincare Anti-Wrinkle Firming Serum for nighttime use only.
