This is the best Vitamin C serum I have ever used (and I have used many...from the most expensive brands to homemade and in between). It's 20% vitamin C and the pH level is low enough to work as an exfoliant. Most Vitamin C serums I've tried had a ph level that was too high rendering it ineffective, but this is the perfect ph level to work and work very well. It quickly lightens PIH marks and evens and brightens skin tone.

The best way to use this product is at night because sunlight will break it down. I do use it at night and also during the day when I am not going to be outside at all or exposed to sunlight. I wash my face and then apply the serum and wait 30 minutes before continuing with my skincare routine. Waiting 30 minutes is very important because that is how long it takes for the Vitamin C (same thing with any BHA or AHA product) to work, after 30 minutes it has already naturally neutralized itself. I keep this serum in the box and keep it refrigerated to keep it from oxidizing quickly. It's best to use the bottle within 3 months. If it turns a dark orange color, it has oxidized and should be thrown away.

I am thrilled with the results of this product and will definitely continue using this to keep my skin tone even and bright. Love this serum!

I really adore this product. You know they say you should consume 1000mg vitamin C. I personally take my Vitamin C every night plus I apply it on my face. Just a few little dabs rub it in. Our faces need nutrients also. Ever hear of strawberry scrubs? Full of Vitamin C. This bottle will last you few months. Worth the price. I'm 42 years old and my nephew who's 5 just asked me yesterday "how old are you" when I told him he was like but you don't have Grey hair and you look beautiful like my mommy. By the way who's 27. Don't want to confuse people saying this will take 10-15 years off off face but it does help give a youthful appearance after continous use. Besides wouldn't you want healthy skin?

I had an awful experience after taking too much biotin - my cheeks broke out with this terrible cystic-like acne. I began using African Black Soap with this serum and the results are amazing!! I am so happy with my skin and any dark marks I once noticed have since disappeared.

Awesome product!
