The cream texture and finish is the most impressive thing. Feels like there is nothing on my face after applying. My skin texture improved in a short time and some red acne scars are fading.

Female with sensitive skin. Bought this for my husband first but decided to try it myself. Been using for one month and can see improvements. Texture is very light and does not clog pores. My skin looks brighter. Good purchase if you want something fast and free from hassle. I bought a second bottle to stock up.
