I've been using this for several weeks. It hasn't been effective at all. There is no reduction in shine. I don't like that it seems that it would be easy to spill (very liquidy with pop off lid). Messy in general. It also seems like it would be easy to get bacteria into the bottle since you have to continually shake it and the liquid in the bottle is exposed to whatever is on your fingertips at the time. Peter Thomas Roth's mattifier has worked well for me and it lasts much longer (worth the price of 3x more than this...It lasts more than 3x as long and application is much more user friendly). PTR product is very effective. I also tried Philosophy's "Never Let them See you Shine" - Also ineffective (and I am a very loyal Philosophy customer).

Love this! Really keeps shine at bay! I use this under my origins nude and improved, concealer and skin refining powder and it keeps my face fresh and oill free all day!

This product is very effective for me and very economical to use, even though the container is small. I use it in the T Zone only. Keeps me oil and shine free all day long, use under my makeup.

I've used this produce for many years -- probably since it came to market --to control shine in the usually oily T area, especially the nose. It works terrifically, and lasts throughout the day.

I've tried other products to give me a matte finish on the oily areas on my face, most of them much more expensive than this one, this one works best.

No results whatsoever. I actually think my face was more oily a very short time after applying. Wish I could return it.
