Used this for my wedding

Firstly, I have acne prone, dehydrated, sensitive skin. I have a lot of dark almost black scars from my acne and was wanting a vitamin c serum that had a high concentration but that didn't break the bank. Ladies and gents, I've found the one. This sinks and hydrates so deeply into my skin that my very extensive winter skin care routine was halved by including this item. It's light but still packs a punch. I have also used this during very hot summers and it never broke me out, just this, eye cream, and some sunscreen as my moisturizer and I was done. Speaking of eyes, I put this underneath my eyes for some collagen production and I don't think I've ever seen my under eyes so bright. I've also put this on active breakouts and it never irritated them unless they were open wounds, and I think it helped decrease the darkness of the scars later on immensely. This also helped with the look of my pores, preventing furure breakouts, and evening out my entire skin tone. I love this thing so much that I used it for just a month before my wedding and the difference it my skin was unbelievable. It made me glow from within and I got so many compliments. Now, there are some cons to it as well. It does need to be stored in the fridge bc of the high % of vitamin c, it can be a bit sticky and tacky feeling, it also smells like wet cat food which put me off so much but once I saw the results none of these things bothered me anymore. I will repurchase this again and again as the ONLY vitamin c serum that I need. The only time I won't use it is when I use retinol otherwise I love this thing.
