I use this Night Cream over PCA Skin-C and am diligent about washing my face at night and in the morning. The combination of the two creams have help to make my skin healthier and brighter. The only downside of the Skin Collagen Hydrator is there is not enough in the 1.7oz jar. Need to make at least a 2.0 or larger size please. Otherwise I would give this a 5 star rating.
