One of my best buys - I've recently taken to the Dermalogica facials and as a result have bought a few products. This came with a small sized exfoliator and face spray so I felt I got my money's worth (though Dermalogica products are definitely expensive!).
I've been giving myself a weekly treatment - exfoliator followed by the mask which I leave on for a couple of hours until bedtime. It leaves the skin feeling so soft - I've even made my husband touch my face to show him how divine it is! I'm not sure about the photodamage or ageing thing - I never seem to see a difference in either. but my skin is definitely soft, hydrated and glow-y.
Highly recommend this product.
