While this works well, it smells awful. I'll use the rest of what I have but will change to something else when I'm finished.

This product is absolutely amazing. Dark spots fade easily. I have purchased this product on repeat. Make sure to store in cool dark place. The open bottle of product can oxidized if not used with 2 months. This works very well on dark acne or scars. I get bad dark spots with mosquito bites and this product fades the spot. I will continue to buy from this product line.

This stuff smells like rotten tuna! Bottles are very small however the texture is very smooth & it's light yellow in color...after researching ingredients there are absolutely too many ingredients in this serum...it was like reading a paragraph in a book!

Works great I use it with the Deep Vitamin C Capsule Serum. Zero irritation,I feel super hydrated, it’s small but you don’t require a lot and it’s lightweight and doesn’t feel like to much it melts into the skin.But question… is it supposed to smell like a fart?

I didn’t want to make a review just after a few weeks. But it’s now actually well over 4 months of continue use. I use once in the morning and then if I’m going out I use sunscreen. I love active Vit C serum. For years I have use Paula Choice, Naturium and the expensive ones too. I believe you have to switch Vit C every now n then. Let me start with, I thought this Vit C serum would be moisturizing. It wasn’t. It did dry my face so you have to moisturize after. The color has a deep yellow tint. Not a big deal. First few weeks I didn’t see any diff. It took maybe a month til I notice a diff. I don’t know if that’s good or bad. But after a month my face did glow and brighten up. No skin irritation. Quality excellent. It comes in 3 small bottle which was a love/hate, but more love. I love that it came in small bottles so I didn’t have to worry about the Vit C turning brown. 1 bottle last 2ish weeks so it didn’t oxidize before I finish the bottle. You have to buy those thin splatchers to scoop the last remaining product in the bottle. The package comes in 3 small bottle. Leave the 2 in fridge to prevent oxidation, while you use the other one. All in all I love this product and definitely order again. Keep in mind to wear sunscreen and moisturize after every application.
