This serum is a watery, gel-like consistency that sinks into skin like a dream. While I LOVE oils, this more water-based formula really feels like it’s penetrating the skin and supporting the cells many layers down. Within a few days of integrating this into my routine, I noticed the very fine lines (from dehydration!) along my forehead disappear entirely, and my skin was plump and hydrated like never before! One of the wonderful things about Pai’s products is their gentle ingredients, and this serum in particular is designed not to irritate sensitive skin. The Back to Life Hydration Serum gets its hydrating power from hyaluronic acid, coconut extract, and a blend of three indigenous Australian berries. I love to layer this over a hydrating toner (Josh Rosebrook Hydrating Accelerator and Indie Lee CoQ10 Toner are my favourites), applying immediately after misting while the skin is still damp. You only need the smallest amount, so don’t over-use as I did in the beginning! One pump covers my whole face and neck. I follow with an oil, like the Pai Rosehip BioRegenerate Oil or Kahina Argan Oil.
