    Edit/update at the bottom. Vitamin c is one of the gold standard ingredients in skincare for generating collagen in the skin. It can be just as effective as tretinoin. Unfortunately, my skin...

    Excellent product. I was skeptical at first, but after just a few applications my skin looked firmer, smoother, and brighter. I have sun damage on my chest—the skin there is rougher and redder than...

    I literally just re ordered this for a second time. I really like it and as I was nearing towards the end realised I definitely don't want to be without it. I am really satisfied with this for the...

    I'm not new to the C serum game, and gave this a try for a couple of reasons. I had most recently been using Ole Hericksen for well over a year. I felt as of recently it really had not been doing...

    This serum came highly recommended from skin care board (thanks ladies - xoxox!) It's a great Vitamin C serum for sensitive/acne/reactive folks as it has only 2 ingredients instead of a laundry...

    Liking it! I believe a good C serum should be part of any anti-aging routine, so when this came so highly recommended by the experts on the skincare board, I was on board. To begin with, it is an...

    This serum has been an absolute life saver for my skin! I've tried vitamin C serums in the past, & they have irritated my skin something terrible. I am 2/3 through this bottle & have already...

    No one is more shocked than I am at how much I've been enjoying this serum! I had in my mind that my skin simply couldn't tolerate L-AA, at any percentage or frequency, after the two serums that I...

    My skin is very finicky but this does not cause me any breakouts at all. I have combo skin and I noticed my skin looks a lot smoother, hydrated and tightens my pores! I was not expecting any of...

    A nice serum that smooths and clears my skin making it glow. It does smell horrid though. It does cause breakouts on my oily skin areas so I only use it in my dry, or normal skin areas. It does not...

    I had to stop using this after about 2 weeks. My face broke out like crazy and was very blotchy. This serum is also very oily and sort of just sits on top of your skin. It only has 2 ingredients,...

    I've got to be on my 4th or 5th bottle of this. I absolutely adore this product. The bottle is nice and dark to prevent sun damage to the vitamin C and the dropper is really convenient. The...

    I'm on my second bottle. Obviously I like it. Doesn't break me out. Seems to help even-out my skin tone. I'm happy with it so far. First, I put on the CSI CoQ10 toner. Then the Vit. C...

    Purchased the CSI Vitamin C + youth serum to try and help fade some red marks and various freckles/uneven tone. This is a preliminary review as I have only been using this for less then 2 weeks but...

    Excellent product. I am on my second bottle. Seems to tone & firm the skin. Makes my nose pores very small . . . a totally unexpected plus. Doesn't creep into the eyes. Compares very favorably...

    I've used expensive serums and prescription creams including triluma and retinol, so I think I have a good sense of how potentially good skin products should work. This to me is a great addition...
