ISNTREE - tenaciouskace review for C-Niacin Toning Ampoule

I have been on a hunt for a good niacinamide serum since my not so pleasant experience with The Ordinary. (10% was too much for me) With an oily-combo pigmentation prone skin, I know that Niacinamide as an ingredient will really help me in targeting those concerns. A little over a week ago, my skin decided to flare up bec it's that time of the month, had some redness and some pesky pimples on my chin and around my jawline. That was also the time that I received this ampoule, and I thought "this is actually the perfect time to test this out!" Fast forward to now, exactly 7 days after using the ampoule, I can already see some improvement. This is very impressive bec I know that it will usually take weeks-months for you too see significant results from a product. And it actually blew my mind that in that small amt of time, this product has already worked its magic on my skin. (speaking from my own exp) Isntree C-Niacin toning ampoule contains 70% Sea Buckthorn fruit extract, a fruit containing high levels of Vitamins C and E. It also has 2% Niacinamide. With a lot of controversy surrounding vit c and niacinamide being used together in one routine, formulating them together in one product is a genius idea, it gave me peace of mind. They used sea buckthorn instead of pure L-ascorbic acid to make it more stable and less irritating. Korean skincare FTW! This ampoule is very lightweight and fast absorbing, it won't give you that tacky feeling after application yet you will still feel very hydrated.
