What is the percentage of Vitamin C in Quench?
Quench is not a standard Vitamin C Serum, it is a combination of three different formulations of Vitamin C and other supporting ingredients designed to increase the effectiveness of the product over standard Vitamin C formulations yet is well tolerated by all skin types, even sensitive skin. Each category of product has its own unique percentage and therefore we cannot give you a standard concentration comparison that you are used to seeing.
Can vitamin C irritate my skin?
While there is a lot of chemistry involved when formulating a vitamin C serum, we use 3 different forms of Vitamin C and other supporting ingredients designed to increase the effectiveness of the product over standard Vitamin C formulations yet be well tolerated by all skin types, even sensitive skin.

I set this aside until I finished a bottle of serum from another brand. I was shocked and upset when I finally used it to find that there wasn’t any seal to protect the serum. The serum released with just a pump down — does that mean it was oxidising during the shipping process and storage? The serum itself is smooth but will need more time to see its effects. Will update my review later.

I am thrilled with the Trifecta line of products from Dr. Karam. the Rinse is excellent; cleans thoroughly but doesn't dry. Quench has helped with skin texture and the Illuminate has been very effective. Again all products do not dry, and in my case of combination skin with breakouts, it's been excellent. No clogged pores, oily feeling or breakouts.

I don’t usually write reviews but this product is so nice. My skin has never been smoother and I’m getting regular compliments on my foundation which I have to explain ‘it’s not my foundation you’re liking.’ I’d highly recommend to start here if you’re curious about the products but don’t want to invest too much money on your first purchase.
