"This vitamin c truly makes your skin glow! I love this product and will never be without. I use it twice daily and my skin has never looked better and that’s saying something as I’ll be 46 years old in a couple weeks! Highly recommend!"
"I have mature, oily, acne prone skin and have found that I just prefer a 20% THD Ascorbate over other forms of Vitamin C. This serum is light, absorbs well and layers very easily with other products. No pilling with makeup etc. I love the additional anti-oxidants/actives in the ingredient deck and incorporating this serum (alongside a couple others) into my AM routine. I do find this a little more hydrating so tend to use it more in winter than summer."
"The only Vitamin C my sensitive skin can handle. Love that I can also use this under my eyes. Fantastic product"
"Recommend this product. Not irritating my skin but leaves skin moisturized and soft. It is in carrot orange color and has a fishy smell, but i gues that’s how it supposed to be."
"I’ve been using C-Boost consistently since they started to ship internationally and I incorporate this product at night with my Truology Vita-A Serum, absolutely Love the new delivery system and I’m hoping that the other products will eventually all be like this, it’s much better than the twist cap, which I did have a couple of the twist caps break on two of my Barrier Creams and One on my Vita-A2 Serum, other than that, my skin has never looked so good and I hardly wear makeup anymore, I feel confident enough to leave my home with no makeup, just a tinted sunscreen."
"This is my go to vitamin C serum. My skin is brighter and it’s very hydrating. I’m 66 years old and people cannot believe my age. I have been using this for a year now and I cannot be without it. It’s difficult to find a vitamin C with this awesome ingredient deck."
"This Vit C is the BEST in its class. It’s like a blanket providing hydration , moisture and glow. It not only protects your skin but changes and enhances it!! I used several bottles of this and will repeat purchase for sure. It’s amazing in the winter esp for me. I love it!!!!"
"My pigmentation seems lighter and my skin is calmer as well. Goes well with other products as well."
"This is my new favorite vitamin C. I have rosacea and this has cleared some of my redness and does not irritate my skin like other vitamin C serums have. Cant recommend enough for sensitive skin!"
"Since using this and other Brianna recommended products I get so many compliments on my skin!"
