I started using this product about 2 years ago. My esthetician used it on me during my facial. I liked the smell of it. I asked for a sample. I used it in place of a night time moisturizer. I have oily skin, but I still wanted something for my skin. My esthetician told me that this serum basically helps bring your newest skin cells to the surface. I LOVE IT! A little bit goes a long way and it is not thick or slimy. My skin absorbed it quickly. It has a nice citrus type of smell. I don't typically use it in the morning, unless I am not going to wear make up that day. This product keeps my skin feeling soft and I can tell that is so much more smooth than when I don't use it. I use it after I cleanse and tone my skin.
I purchased this product at my local Merle Norman for around $40. For me, one bottle of 1 FL OZ. lasts about 8 to 10 months.
