I'm using it for 2 to 3 years now and I'm really happy with the results

This is by far the best vitamin C serum I have tried! I am on my second bottle and love how my skin looks! Such a difference!

I am only using this item for 3 weeks and haven't really seen the result

I love love love this stuff! Best vit C I have used.

I have been using this serum for a solid year now and I am very pleased. It has an oily base to it that absorbs easily into the skin and feels nice under my SPF moisturizer.

i am obsessed with this stuff. i've had it for over a week and have noticed: bright, glowing, soft, smooth, and moisturized skin. my pores have decreased in size, which is a big reason for loving it so much. i can't recommend it enough. i'm eager to see the long-term results. patience is key!

This product is simply amazing!! I've tried other brands for significantly more money and I'll never go back! I've been using this product for two weeks now and already see significant improvements! I'm very disciplined with my skincare routine so I follow the directions and use it consistently! My skin is glowing!

Good product but be careful of skin reactions. I love Neostrata products and have used them for years. I think there needs to be more instruction to use the vitamin C sparingly until you know your skin can tolerate it.

It is amazing how my skin looks young and fresh and moistrazid

I absolutely love this product. It came with the face wash and I used it immediately afterwards and honey my face was so smooth and soft and super clean without feeling dry and it was super absorbent without feeling like it was greasy or sticky. Wi
