I teach makeup/skin care classes, and this product is No. 1 on my "Must Use Daily" list. It's been my personal favorite for years, and my own skin is testimony as to the efficiency of what I teach! It's as close to "miraculous" as a treatment can get!

This is a great product. I use it on my face as a night cream. I am 74 years old, but people say my skin looks like I am 50+.

This has long been one of my favorite products. Your company provided it at the lowest cost of any on-line retailer. It arrived very promptly, well-packaged.

good vitamin C serum

This a good oil-based vitamin C serum - especially for me with dry skin. I was initiated into using this product by a lady in a sundry shop selling natural skincare. She said the skin gets better and clearer with time. This is true. I find my facial skin becomes very smooth. I buy from iherb because it is best priced. Thanks.

Good for hyperpigmentation and moisture

I think this product is good for hyperpigmentation as well as moisture. But I think the product has made me break out in some pimples and whiteheads due to it being a big oily. But I have kept using it anyways and those problems are clearing up.
