I have definitely seen a difference in my skin color, puffiness gone under eyes and dark circles are much better. I use it under my day and night creams.

Great product! Recommended in a Instyle article as one of the best vitamin C. I'm on my second order. My face is extremely soft, hydrated and brighter. Great price as well.

I`m sure there are more potent vitamin C serums but this one is potent and well worth the money. Doesnt irritate my sensitive skin and it`s fragrance free.

I really wanted to like this because of all the positive reviews, but this actually made my skin worse, resulted in Acne breakouts on my cheeks and jawline which I never get!Would not recommend if you have sensitive skin.

Works as described. My skin looks great, smooth and even toned. Almost 60 yrs old, and this is a new part of my skin care routine that helps my skin look flawless!

Love this product! Not oily or greasy at all and goes on super smooth! Love how it makes my skin feel. This is my second bottle and I intend to keep purchasing it! Great price too!

I've been using this product every morning and night for two months. My skin is definitely brighter and firmer, and my fine lines are definitely less noticeable. This serum has even seemed to help with healing my breakouts more quickly.

My skin is really looking this serum. I use it with the Vit C moisturizer and the Vit C cleanser. Use all three in the morning. Skin is softer, clearer and brighter.

I`m liking the serum. I like how it feels as I apply it. I`m seeing some results, but I am African American so I feel my dark spots will take longer to see more results. But I will continue to use until I`m out and will order more :)

It completely broke me out. I'm so upset because I really wanted this to help lighten dark spots and it essentially just created more after I broke out.
