It's not a miracle worker - ie, my spots haven't miraculously disappeared after using this - but it does help to calm break-outs, minimize their appearance and I really do feel like it does something positive to my skin. I bought a smaller 125g pot which costs £4.95, but I'll definitely be investing in the larger 315g pot at £8.75 because of the longer shelf life! I've used the mask maybe 5-6 times already, and my tub is still 3/4 full. You don't need to use a lot of the product, and I tend to use it just on my problem areas (chin, jawline and t-zone).
What do you reach for when your skin is throwing a tantrum?
