ObagiProfessional-C Vitamin C Serum – Helps Brighten Skin Tone and Minimize the Appearance of Fine Lines & Wrinkles – Safe for Sensitive Skin

Q: doesn't this contain propylene glycol and isn't that antifreeze?

The short answer is yes and no. Propylene Glycol is something that can be used to either prevent something from freezing or change the temperature at which something freezes and it is part of a group of substances which can do that, BUT I believe you’re thinking about the kind of anti-freeze commonly used in vehicles, the one which we're all warned against drinking because it can be poisonous to humans and many pets. That substance is Ethylene glycol not propylene glycol and ethylene glycol is considered poisonous because unlike propylene glycol which is either excreted from the body in urine or turned into lactic acid (something our bodies have no problem processing), when our bodies try to process ethylene glycol it starts to affect the central nervous system and can ultimately result in kidney failure (from the buildup of compounds the kidney can’t effectively process) and ultimately death. Propylene Glycol is generally considered safe for human consumption and exposure up to certain limits, but if you consume too much or are allergic to it then you could have an adverse reaction. For more information here’s what the CDC has to say about the extent to which propylene glycol could ever be a problem: https://www.atsdr.cdc.gov/phs/phs.asp?id=1120&tid=240 And here’s a great basic discussion about the differences between Propylene and Ethylene glycol and the science around the safety of propylene glycol: https://www.healthline.com/nutrition/propylene-glycol#section4

Q: Why is the serum I received yellowish brown when it should be clear?

I’ve experienced the same change in color of my vitamin C serum. My skin anesthetist said vitamin C turns yellow over time when it’s exposed to heat and light because it begins to crystalize. I asked her if the color change indicates a loss of potency. She said there is no consensus but most experts consider any loss in potency insignificant compared to the benefits of using the serum.

Q: Okay. There are two 20% C-Serums. What is the difference between Professional C-Serum 20% and Medical Professional Serum 20%?

One serum contains 4% hydroquinone and the other doesn't, however this one is advertised as containing it but when I received my shipment nowhere on the ingredients was it listed. For the extra price it should have had what I was paying for. It will go back, if I wanted just the 20% C I could have gotten it for $20.00 cheaper. Hopefully this was just a shipping error and not the seller it's self. Since I won't know for sure I am getting a refund. On the products themselves, I have used both serums and they are very nice, the one I wanted is better, gets rid of sun spots and really makes your skin glow.

Q: I have mature very oily skin. Does it make your skin oily and break-out?

Hi There, this is not oily, it is a water based serum that absorbs into the skin. I would gradually add it into your skincare routine to avoid irritation being that it is a medical grade 20% vitamin C.

Perfect serum

I’ve been using Obagi products over the years. Vitamin C serum plays an integral part in maintaining my skin healthy clear luminous . Always layer this with moisturizer. / oil to seal skin hydration . Once a day is enough but sometimes during cold seasons - I include retinol during the night anc Vitamin C during daytime ! They work well as my skin care routine !

Brightens and Smooths – My Go-To Vitamin C Serum

I've been using the Obagi Professional-C 15% Vitamin C Serum for several months and have noticed brighter, smoother skin and fewer fine lines. One bottle lasts me around 6 months with daily use, so it’s definitely worth the investment.The serum starts out clear and gradually turns yellow over time, which is normal for vitamin C. To help limit oxidation and prolong its effectiveness, I keep it stored in a cool, dark place. The one pictured is 6 months old and at the end of its use.It absorbs quickly and layers great with my other skincare. A must-have in my routine!

Obagi 15% Vit C serum

It goes on easily and feels very good and moisturizing. Soaks in pretty quickly. I didn’t find it sticky at all. I didn’t find the scent offensive. It’s pretty mild smells rather fresh and clean. We shall see how effective it is as my dermatologist recommend this for me for age spots and dry scaley skin.

Works wonderfully

I did notice the scent was stronger and it was a slight different color than the one I got from my Med spa but my skin is looking incredible like it did when I used the one from there and I can feel the same effects from it that I did from the other. Ex. It tingles in the morning if I had sun the day before. My face doctor told me to hold off on tretinoin for awhile and only use this and my skin looks amazing! Many compliments. I would buy it again!
