I almost gave up on this product after finding it had a really gritty texture when applied after other products. I mixed it in with the ASAP Super B complex and it made a world of difference! The product was definitely good for brightening once I got over that little hurdle, would recommend.
I like the packaging because it makes me feel better about the stability of the vitamin C. The texture on the skin is mattifying which is interesting. It does not layer well with my HA but if i mix the HA with my moisturiser it is ok. Vitamin C does sting a little on dry patches but once applied it does not irritate.
