Best vitamin C serum
I’ve been using ZO products but they only have 10% vit C serum , so I switched to original Obagi 20 % which I believe is better for my skin ! My skin looks glowing and brown hormonal patches are almost gone .! I love the smell and how fast it penetrates the skin , and it lasts a long time !

Excellent product
Since I started using Obagi Professional-C 20% serum, my skin is noticeably smoother and brighter without any dryness or irritation.

Love Love Love
I love the Obagi Professional-C Serum. I've been using it for a couple weeks already feel like my dark spots have lightened, my skin looks brighter and smoother. I have not had any bad reactions from the product and lately my face has become sensitive. My skin has become pretty oily in the past 6 months (hormonal) and this serum feels so light. I also apply to my neck and chest. I've been using it every morning and night. I bought a bottle for my mom to try just recently. She uses a different brand Vitamin C but I'm sure she will be switching to this one after trying it. This is one of those items I want to overbuy in case it goes out of stock or discontinues. So great!

Best C Serum around
I’ve tried other c serums that were less expensive but I always come back to this one. It goes on so nice and absorbs completely in less than a minute. My skin looks healthy and glowy even without makeup. It brightens my skin and helps minimize pores. For me it is worth every penny.

Obagi makes the best C Serums
I have 15% and 20% and switch them around depending on how my skin feels after washing. Does absorb well, but for my skin, takes a longer to absorb than the 15% but only a minute or two.

Best Vitamin C Serum
This Vitamin C serum is professional grade. New customers should start with lower % of Vitamin C and work up. My skin soaks this up. I use in my morning routine and then apply my day cream and spf before my makeup.

Glowy skin!
I love Obagi in general, but this serum is amazing. I use it under my sunscreen as extra protection. It definitely makes my skin glowy and has helped brighten dark spots.

Vitamin C
I love this stuff! I have done my research on Vitamin C for older skin and this is the ticket! Be careful when you open it. I have accidentally tipped it over and spilled the entire bottle. Wish it came in a dripper bottle instead of the glass thingy. This is my new go to product.

Very effective serum
I am in my 80s and have been using this serum daily for 15 yearss. It is the most important part of my beauty regimen. Skin is n excellent condition. . It was first recommended by a doctor He sold the serum, but it was more expensive than LovelySkin Sells it for.

Too harsh for me
I had been using the 15 for awhile now so I tried the 20% and it was too harsh. I tend to have sensitive skin with mild rosacea... I'm able to use the 15 once a week. It's like resetting your face or a deep clean one a week! Love how my skin feels after. Definitely start out with 15 before trying the 20!

Nice C Serum
I have used many C serums in the past and like the difference I think it makes to my face. This Serum feels especially potent. It has a rather strong aroma, but you get used to it. It’s performance is as good as others that I tried.

Not sure
I've only been using for a couple of weeks & haven't seen a noticeable improvement yet. I'll at least finish the bottle & see if it's worth ordering again.

Don’t like the consistency at all
I’ve used the 15% Obagi Vitamin C for awhile and just switched to this more potent formula and the consistency is just not the same. Maybe it’s supposed to be this way? It’s definitely more of a liquid than a serum and doesn’t glide on well at all. I can myself having to go through this bottle a lot quicker since I have to use more than the recommended 5-7 drops since the product doesn’t glide like the other vitamin c I used.

Obagi C- serum 20%
I didn't like the feel or consistency of serum. Leaves skin sticky feeling. I didn't use product long enough to see any results.
