The best vitamin c serum. I like how light it feels and goes on smooth.

I love this vitamin C-Serum since the first time I bought it. I’ve tried different ones, but I always go back to this one.

I really love this product. The texture is great and it makes my skin feel very smooth. I think it’s a good compliment to the other products I use.

I have been using this serum for many years. I like it's thickness and I think the results are worth the cost.

[This review was collected as part of a promotion.] I have been using this product for years after every face wash. It has a great smooth texture and goes on light; only a tiny bit is needed therefore lasts a long time.

I will continue to use the product until I feel it stops working.

Is a excellent product for face

I have used this product for the past 6 years. The product in this bottle is different than the past - looks different, smells different. It probably didn't affect the activity, but I loved the orange aroma it used to have. The worst problem though, is the new formula seems to cause a burning feeling on my skin. I am holding it now, using a different Vit C product, and will try this again. However, I think this will be my last order of this serum. I miss the old formula, it was a favorite part of my skin care routine.
