This Review Title is Works to protect the skin after a treatment and the content is: I'm  new to the Zeriod brand but have had very good experience with Japanese and Korean skincare brands and products. This Zeriod Dermarenewal Revitalizing Ampoule is geared towards sensitive and combination skin. The tube is small but I only need a little drop. The ampoule is quickly absorbed into the skin and protects and hydrates.  It is for additional protection to the skin after a procedure, so I don't use it daily.  Instead, I would use it after a facial or an intense exfoliation..There are other information for this review, one is This reviewer did not purchase it and the other is 1 people think this review is helpful.
