This was my first time trying at a AIO and I was super excited to use it after checking the ingredients list. It's been about 2 weeks since I've been using it  (twice a day - morning and night). It didn't take long for me to notice an improvement in my skin's condition, it's much more hydrated and brighter. Also, I think it makes my brightening serum work much better! No problems with "stickiness" since I always apply products on top of this. Would recommend for its price and size!
