I got 2 freebie sample sets of the serums. It includes the pink - Vitamin A serum, Purple - Chlorella Serum (for dark spots & redness) & the Blue - Hydration.
I have been using it regularly for about 3 months now & it has made my skin look near perfect which is crazy. I have normal to dry skin (being an old bag lol). Before I tried it, I had this one patch of dry skin below my cheek that nothing would get rid of it. I also had several red dots that appeared out of nowhere, not even acne-like. After using the 3 serums for about 3 weeks my skin just got better & better up until now where its just flawless skin. I use it after my Chanel Gel Purete cleanser which I love & have used for many years. I use the pink serum let it soak in a bit, then the purple serum let it soak in & then the blue. I just put some on my finger, rub it together with my other fingers & pat it into my skin including my under eye area. My skin is so soft & hydrated now. It also has made my skin look pore-less & so even. It did not irritate or break me out at all - ever & my skin gets sensitive with a lot of products.
This is the only product from them that I have used. They have a new serum that I want to try next. Everybody's skin reacts differently, but they get really great reviews from others too. Hope that helps dear!
