      How to wear it

      Spray two or three times on pulse points: wrists, neck and behind the ears. Extrait is concentrated, so a little goes a long way. Let it settle rather than rubbing it in.

      Fragrance is personal

      Because scent is so personal, we can’t accept returns based on fragrance preference. That’s why every scent comes in a 10ml try size. If your order arrives damaged, defective or incorrect, contact our support team and we’ll make it right.

      What “inspired by” means

      Adverse Reaction is Barrett’s own extrait de parfum, created to capture the character of Side Effect. We are not affiliated with or endorsed by the house that makes the original; its name is used only to describe the scent.
