I love this range, weirdly Peter Thomas Roth stays below the beauty editor radar but it deserves to be on every shelf in the UK. Everything I've tried from it has been wonderfully effective, with something just a little bit different about the formulation and packaging.
This mask is NOT for the faint hearted, it is very active, I use it as a deep-clean once a week. Do not use if you have sensitive skin. One thing I would say is when applying, massage it on gently (it contains physically exfoliating beads), as the ingredients start working it warms up and feels mildly uncomfortable and if you have exfoliated your face with it while massaging it on this will be stronger. Once your skin is used to it go for your life, you will work out a happy medium.
I find this exhilarating, the mild discomfort energises my complexion and makes it bloom. My make up then looks airbrushed on after this. Genius!
