No irritation at all
No stinging on my sensitive cheeks, which is rare for me. Scent is almost non-existent and the finish is comfortable.

Simple and effective
Pump is easy to control so I do not waste product. It plays nicely with the rest of my routine and never pills.

Skin looks calmer
Results were gradual rather than dramatic, but my skin definitely feels smoother and looks more even in the mornings.

Subtle but steady results
My dry patches settled down and I stopped needing a heavier cream on top. Packaging could be sturdier for travel.

Gentle and it layers well
Took about a month to notice a difference, so patience is needed, but the texture change is real and I will rebuy.

Good value for the size
Nice cushiony feel and my makeup sits well over it. Only note is the price, but the bottle lasts a long time.
