Applied mask again last night, applied moisturiser afterwards, and this morning my skin looked fairly bright. Still a bit flaky. Got a couple of new spots yesterday afternoon so I also applied a dot of the mask to those overnight. They'd calmed down by this morning.
For a cheap treatment, it seems to be working well so far. Certainly hasn't made my skin any worse.
Verdict so far: my skin is improving but I still look better with the facemask ON!
applying again tonight. I know I probably shouldn't apply every night but I have nothing to lose so I don't care
