I have sensitive skin and even using perfume will cause rashes so I am very happy that this serum doesn't cause any adverse reaction. I have used it for 2 weeks now and I did notice my skin seems smoother. I put it on after I washed my face and it absorbed very quick into the skin. Then I put on moisturizer. I only use it at night.

Although I haven't been using this product long enough to see the full benefits yet I have noticed an improvement in the brightness of my skin. In the bitter cold winters my pale skin looks so dull and I do believe this product has helped brighten it up. I see a little improvement in discolorations but I suspect that benefit takes more time. My only complaint is that this serum makes my face feel a little sticky and I need to add more moisturizer than usual following serum application so my foundation will apply easier. But it's not annoying enough to discontinue using this serum. I've used way more expensive serums that delivered the same result. I'd buy it again...

I bought my first bottle of this product in the fall, and just ordered two more bottles. I require Vitamin C for my rosacea, and this serum has a higher potency that the much pricier Vitamin C in the skin care line at my day spa. I am at the point in my life where my skin care regimen is multi-layered, and the thinner viscosity of this serum is the perfect weight. After two months of use, my skin is brighter and the fine lines have softened. I highly recommend this serum.

His serum is light and feels great on your skin! A little bit goes a very long way. My skin looks brighter feels smoother and that dull look I felt like I had is gone within a week.

So far so good. I really like this because it does a fairly good job of brightening my face and making it seem less sallow. The serum is also fairly lightweight which is nice compared to some oilier stuff I've used in the past.
