It is 20 percent vitamin C, which is high. Some people need to start at 10 or 15. I like it. I put it on my face in the morning before I apply sunscreen.

I have seen a difference in the overall tone of my skin. I have previously been using another serum & had amazing results. Adding this one along with that one to my regime only boosted those results.

I've been using this product for a month and my skin looks amazing! It's soft and scars/marks are less visible. I love the results so much I have purchased the Retinol serum. I can't wait. Thank you!

My skin is relatively sensitive with a combination of dry and oily skin. But, I have noticed a smaller pore with brightness increase, after using this serum!

I think the product it working great! I was also really impressed with the customer service this company has. Very professional and informative. Excited to try more products with this line.

Literally, few days I see a difference in hyperpigmentation. It goes on nicely and dries quickly. I`m always afraid that something is great in the beginning but stops working. But let`s see.

I was super excited to try this product after reading all the reviews. Unfortunately this serum caused more breakfout on my face and I've stopped using it.

I will be posting pictures soon but this product is amazing! Like I really seen a difference in a week! The only things is my fave gets a little dry once it dry! But I love it and i will e purchasing more

This serum is life!! I use it daily and it keeps my skin glowing along with the rest of my facial routine. Def recommend. Be sure to apply a thin layer or else it leaves skin tacky

I originally bought TruSkin Vitamin C Serum for dark spots on my face. It has helped a little on the dark spots, but what I found was that it tightened my skin. I have bought my second bottle now and will continue to buy this product.
