Cellex-C Advanced-C Serum
I have tried other brands of Vitamin C facial serums and find Cellex C to be one of the the best.
i have been using cellex c since it came out in the 1990s. as i recall, it was the first of these types of products and in my mind the best. i have tried others but always come back to cellex c. it really brightens aging skin!
Wouldn't be without this product. It is amazing. Use it diligently with the Hydra 5 B and you won't be disappointed.
