Review (4/5): It does works but not sure if it is worth the price...
I purchased both the nighttime and daytime samples. Overall great products but the price is a little steep in my opinion. The Pixi brand has a great alternative glycolic serum, vitamin c serum, and oil blend for much cheaper and works just as well. I did however really enjoy the B-hydra serum and am considering purchasing again. The vitamin c serum had a weird smell though that was off-putting but did slowly fade acne scars over time.
