    I use this product when I don't have time to do the full Obagi system in the morning. Vitamin C is an essential serum for the skin. The product is easy to apply and very light. After cleansing, applying the toner and then the C serum. Be sure to use moisturizer and do not forget the sunscreen. Obagi has a excellent line of products for all skin types.

    This product is either old and/or not authentic. Vitamin C serums should be clear or a champagne color. This serum from Overstock is yellowish/brownish in color indicating it's oxidized. Shame on you Overstock! When the price is to good to be true, buyer beware!

    Absolutely love this serum. It was recommended to me by a colleague whose skin always looks astonishingly youthful and bright. I found it for a great price here on Overstock, and have not looked back since. In fact, I have a entire skin care routine with another brand but this is the ONE product that I can not live without! My skin has improved texture and elasticity, and it looks healthier and brighter each time I use this serum. I whole heartedly recommend Obagi Vit C serum to anyone! (For information’s sake, I am 49 years old and have normal skin)

    I have been using the Obagi System Professional-C serums on and off for years. I recently moved and let my skincare routine go for awhile. I just recently re-incorporated the Obagi C serum back into my morning routine and I feel good about it. It has always done me good in the past, particularly with skin clarity and tone. I think over a longer period of time it will also impact the firmness of my face and neck. I recommend this particular brand because it is less sticky than some of the others out there.

    I have used Obagi products for many years and started the Professional -C 20 serum several years ago. I have seen a difference in the small visible lines on my face.....they are not as noticeable or some have disappeared. The texture/tone of my skin has improved greatly. I highly recommend this product and all products by Obagi.

    This is a professional quality serum for a better price that a very popular brand that is more expensive and seems very similar. I will buy Obagi Vitamin C serum again.

    One of the best (if not the best) skin brightening serums on the market. I was first introduced to the obagi vitamin c serums at a doctors office. Note it takes getting used to because it will peel your skin when you first start using this, but what is underneath the peel is absolutely amazing. After about of month of biweekly use it stops the peeling process and just brightens your skin. People always ask me how do I get my skin to look so great...this serum has been my fix for the dull patchy skin that I used to have.

    I have been using the Obagi system for years and the Vitamin C 20% serum is my favorite. It makes my skin feel great. I use it in the morning and RetinA .008 at night. Together, they have helped brighten and plump my skin. I took a chance and purchased this at almost half of what I pay for it at my plastic surgeon's office and it is exactly the same.

    I have been using this Serum for about two years after my dermatologist recommended it. I use it every morning under a 50spf cc cream and at night after taking off make up and before I apply moisturizer. I can honestly say that at 60 my skin looks better than it did at 50 or even 40. It is a simple routine that really works. This Serum has a slightly oily feel when applied, but totally absorbs within a few minutes. Over time, any discoloration or unevenness in my skin tone completely cleared. I never want to be without this product - well worth the money!

    The lid on this product is loose and will not seal tightly which makes a *** Vitamin C serum USELESS and exposed to air constantly. The lid will not screw tight and leaks constantly. Very disappointed. No expiration date in sight.

    I loved this product. I’m using it only a week, but I already see a big improvement in my skin. It has a little tingling sensation when you apply it which indicates that product is working. The box and the bottle didn’t have an expiration date, but did have the same lot number on the box and a bottle. I called the Obagi customer service and asked them about that, and by that lot number they said that it expires in 2021, two years from the time of purchase. The product itself is authentic. I’ll buy it again.

    I first tried this product from my doctor. I wanted to improve the lines and skin tone on my face and chest. The first day I applied it on my chest I could see the lines to be less prominent. After about a week my face had a better tone. I love this product and would recommend to try it!

    Love this serum -- keeps my skin glowing and refreshed. I use a bottle then go off it for a few months as my skin gets used to it, so i need to alternate to something else for awhile. When I return to it my skin loves it all over again like new.

    Outstanding product that I have used for approximately 14 years. Thoroughly protects my sensitive skin without causing dryness. I use it on a daily basis and find that it works best with a little layer of moisturizer over it.

      These are brand new and unexpired products. Yes, they are authentic.

  • Q:

    "what is the expiration date on this product and the number 5 brightening pm lotion by obagi as well. thanks"

    • A:

      Hello julestobin, the Obagi System Professional-C 20% 1-ounce Serum, does not have an expiration date. Have a great day.

    • A:

      If Vitamin C has no expiration date, it may be synthetic. My Vitamin C turned brown and smelled bad when I didn't use it quick enough!!! Not sure you are evidence-based on saying there is no expiration date.

    • A:

      I contacted Obagi customer service about a bottle of vitamin C serum that I purchased last year. (Not through overstock), and I would like to share the response I got back, hoping it may help answer some questions. Being an avid user of this product, the coloration of the newly purchased bottle made me question. While there was no expiration date, they were able to look up the Lot number. 13K1174 This was mine. This is the response I received. "The product shelf life would be 3 years and based on this lot number this product was shipping late 2013, so it is going into its 3rd year. The product can go from clear to pale yellow with age and also if not stored correctly as it will be sensitive to heat and sunlight exposure. If it does become a deep orange brown it would be oxidized and while it would not be harmful it would not likely be very or as effective. We would recommend returning to the point of purchase to exchange. " I hope this is helpful.

    • A:

      I have been using this for over 10yrs and is by far the purest and most effective C serum out there.
