This product is exactly what I needed. Seems I always have a shiny nose and powder just wasn't doing it. So, a little dab of this on top of my make-up does the trick.
I have used this product in different ways, and it works. Have used it in humidity as well, it definitely cuts down the shine instantly, but requires re-application.
Before makeup : After moisturizing the face, I let the skin soak it in, and then apply the mattifying gel. It instantly cuts down the shine. I apply it only on the T zone. It does not feel like you have too much on your face since only very little needs to be used. It spreads easily too. After applying the gel, I give it an extra minute or two, and then apply the foundtion / BB cream, in dabbing motion.
After makeup: Again, I apply only on the T zone. This time I let the foundation/BB cream soak in the skin, and then apply the gel in patting motion, with my fingers. It instantly mattifies the skin. I will share that initially I applied the gel in sweeping motions and ended up mixing the gel and the BB cream, which wasnt nice of course :)
