The Good C Vitamin C Serum

I got a sample of this product (thank you to Nordstrom for this option to choose and get free samples with the cosmetics order, without spending your money for products which may not work). I applied it before bed (after washing my face with Lancome Cream Radiance cleanser, Clinique Clarifying solution, and couple Laneige products: Water sleeping mask and Water bank moisture cream), I noticed how micro fine this serum was and that there was a good chance to be absorbed especially in my neck area (I have hard time to find products which are absorbed and work for my neck). I felt a bit of drying (i applied it too generously on face and neck), that's why I applied a bit of Bobi Brown extra repair moisture cream on top of it. Next morning I really loved the result, I could notice some good youthful effect on my face, especially in my bottom part of the face which is difficult to get with creams for me, and I noticed a very good effect for the lines on my neck (my dermatologist said that I'm developing those fine lines due to the way I sleep: on the side with my head on the raised arm.. bad habit, I'm trying to use travel neck pillow on top of my regular pillow instead of my arm now to keep my arm down). Very promising serum which I'm planning to order after my sample is gone. I attached the pic of my neck to share if anyone has similar problem (sorry for my everyday pj look these days :), I like my comfy Nordstrom Moonlight nightshirt by the way)). I have low iron and it could be that my skin is in need of good source of vit. C which can explain its good effect. Overall seems to be an amazing product for me and great find.
