“Love the product, I had used other famous brand of Vitamin C, but always irritate my skin so badly. This product is very gentle, gives my skin hydration and it helps my sebaceous glands not getting oxides easily”
“I’ve had trouble finding the right Vitamin C serum for my sensitive skin until I found this one!!!! Doesn’t irritate my skin & gives n mye a well needed glow, highly recommended!”
“Like every product I use - the Efficia C is giving my skin glowing healthy look and leaves I moist. It also is a good make up foundation. I actually prefer loose powder from Synergie.”
“I have noticed since using effica c along with other synergie serums, my skin appears brighter overall. A small amount of application seems to go a long way,”
