    A Must in My Routine

    Posted by Jeannine on 16th Dec 2013

    I've been using this for several years as part of my morning routine (wash face, Vit. C serum, moisturizer with SPF, makeup). Maybe once or twice a year, I try out something else, and I can tell the difference and come back. The Vitamin C serum really works. Combine it with an evening retinol product, and you'll take 10+ years off your age easy.

    You can't go wrong with this C Serum!

    Posted by Debbie M. on 13th Aug 2013

    This is an excellent C serum of the same caliber (and often offering a better texture) as Skinceuticals, Cellex-C, IS Clinical, etc. Why pay 2-3 times as much for the same thing. You can't go wrong if you are looking for an ascorbic acid product!

    Love this serum!

    Posted by Mary Ellen on 13th Aug 2013

    I saw this recommended for hyperpigmentation, my major skin concern, on MakeupAlley, so I decided to give it a try. I'm very glad I did. Three drops of this simply formulated, clear, light serum is enough to cover my face and neck completely, and it does not interfere with sunscreen or makeup application. I have had no stinging, irritation, or redness from using this, which, of course, made me wonder if it was doing anything. It is. I've been using it daily for three months now, and my skin is consistently hydrated (even in the heat and sun of an AZ summer), looks brighter and more even-toned, and I have noted some fading of my melasma. Pure Skin Formulations' customer service is great, and the price is extremely reasonable. I highly recommend this serum to others.

    Well formulated. Great value. This product can compete with the best Vit C products out there...for less than half the price.
