It`s okay at best. I have used different brands of Vit C serum and seen noticeable results so I was expecting the same from this product. After two months of use, I still don`t see a difference.

I have a very sensitive skin and was skeptical about using any new product but the Truskin serum has worked well for me and I would recommend it to people

I didn't think this would work, but I swear my face never looked better. The woman who does my facials asked what I've done different and this is the only thing I have changed.

I have started using this serum and can see some difference. skin becomes little dry after applying it but it`s every effective. One can use 5 to 7 drops and it is enough to cover the entire face.

It`s a great serum! Lightweight, it made my face softer. I like this brand serum better than the different brands i purchased from the past. So far so good, no complaints! And good customer service too!

I liked everything about it. I also use the C-plus which is even richer than just the C. I think the retinal ingredient iseven more effective. Both products are amazing and people are shocked when I tell them I just turned ninety!!!

I love this stuff! I've been only using it for about a week and a half and already seeing results. My skin looks more youthful, bright, and is so soft. Customer service is beyond excellent as well. I am a forever user now.

This has really helped my acne scars and makes my skin glow! It also didn't make me breakout which was a huge relief because my skin is crazy sensitive.

I am on my fourth bottle! This stuff is amazing. I ran out once but I won't make that mistake again. It keeps my face feeling refreshed and vibrant. Highly recommend.

I use this during the summer months to counteract the effects of the sun. Great ingredient list. Effective in preventing damage and even lessening minor fine lines.
