So very silky and effective. I use this in my morning skin care routine after washing and before sunscreen. I've noticed a difference in how my very dry skin retains moisture throughout the day. Also effective on the hands.

I love this stuff! I have very sensitive skin and this is a stronger C Serum than I was previously using. I was afraid that it would be too strong, but I have had no problem using it once a day. It’s a great price, too,

Best of all but it came without a box, I don't know why!

Been using about a week noticeable change the 1st day.

Product leaked during shipment . Cleaned up bottle. Had lost over 50 percent of product., Reason 4 stars GREAT Product. Have sensitive skin it feels fabulous. Too soon to know results. Would but again. Manufacturer need to work in bottle seal.

Oddest shipment ever received from a Sam’s order. Arrived separately from my other purchases. Item was shipped in a wool ball box and wrapped in newspaper. Have not used product to rate it specifically.

Goes on well, easily absorbs. I thought it would have been a thicker substance, but isn't. I haven't noticed a real WOW look on my face and neck.... so haven't seen much of a change in my skin or that it's even doing anything. Has no smell.

I know it says 20% C but I have used another brand that seems to be much better at fading spots.

I received this product damaged. The bottle had leaked during shipping and 1/4 of the bottle had been absorbed in the cardboard package. The product says imported but does not list country of origin. It also does not list the percentage of vitamin C. The first ingredients are water, glycerine and proeylyne glycol. The manufactured date was 4/21/2017 so this was not fresh. I will be returning.

Label ingredients state Niacinamide (Vitamin C). Niacinamide is B3 NOT C. Later they list Ascorbic Acid. That is the Vitamin C! I don't trust a company that can't even get the value of their ingredients correct.
