Wow, what a duo! The wow wow wonder has a lovely texture and my skin slurps that serum so quickly! The retinol cream is more easily absorbed when I use my gua sha and face roller tools. I am definetely starting to see the difference on my skin: more even tone, less blemished, the dark spots are more faded, my pores are less open, my skin is soft and glows!! I'll be repurchasing these products again!
