Great product!
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!

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.

C-Boost
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.
