This is an Olay Total Effects campaign, executed by Saatchi & Saatchi in Dubai. The campaign touts a minimalist and clean-cut background, and depicts numbers representing the ages of various women. However, one digit is disguised behind an Olay product, which confuses viewers and forces them to  "keeps guessing" how old she is. Also see other advertisements from this campaign that ask  "Is she 31? or 20?"
