This one right here - my holy grail.
Bought it with the mindset that I would use it once a week, as a deep moisturizer treatment, ended up using it almost every night.
I do have an oily T-zone but so far, no breakouts. If I do get some, I'll stop using it so frequently but I'm still going to try to find a way to insert it on my routine now and then, because seriously, the skin is SO soft Show more

If you’re super duper mega oily and live in hot, humid weather, then this toner is definitely for you. It’s incredibly effective in terms of oil control. I have combination skin, and this toner really helps manage the oiliness in my T-zone.
It’s doing such a great job at oil control that even my cheeks, which aren’t oily, ended up feeling dry. Clearly, it’s really effective at controlling oil.
This brown liquid is so golden! It keeps my skin pretty matte/satin-ish all day. I live in Florida, so its always humid and hot for the most part and with my combo skin, I tend to have a shinier t-zone daily. So once I started to realize that my t-zone wasnt looking overly shiny after a few days after first use I checked the bottle again and saw that it has sebum control. Love!
