Its great that this is a 3 in 1 product but I find I only use it mainly as a mask.
I do have blemish prone skin, but I found the scrub too harsh and drying to use daily.

As a mask I use it twice a week, leaving it on for 10 mins then washing it off. This definitely tightens pores and helps control oil. It also helps with getting rid of blackheads.
I only use it once a week in winter as it can get too drying.
Cant say I have noticeably less breakouts with this but does help with drying existing ones out. The mask does some exfoliating as its washed off as well. Leaves a fresh clean feeling.

I would not advise it for dry skin though.

This bottle lasts me about a year so definitely value for money.
