Satisfactory

I was reasonably satisfied with this purchase, but as a 49-year-old who regularly uses highly reputable French products, I can’t say I was truly impressed. Once I finish this bottle, I’ll be seeking a replacement. My decision to try it was based primarily on the strong ratings.

Obagi Professional-C Serum

As with all products, it works well. As I have mentioned before with other products, there isn’t anything on the market that can reverse aging other than trying your best to keep your face in good condition with products or pay for expensive surgeries

So far so good

It brightens and skin looks healthier. Need to give it longer to see if it stimulates collagen.

Love Obagi’s Vitamin C Serum

Love this product and have been using it for years. Started with the 10% and worked my way up to 20%. I feel it gives my face a nice glow. Only down side is the price. I can only afford to purchase this product when it is on sale.

Obagi C-Serum

Goes on well and absorbs into skin, just a little tacky so I wait until it dries and add moisturizer to seal it into my skin.

Nice product

Apply drops of this vitamin C serum on your fingers to smooth on face and neck. This liquid smells wonderful but the applicator could use some improvement since it has a tendency to drip down the bottle if you’re not careful. It’s a great product at this price point but I feel there are a few better products on the market

Good for the price point

This C is good for the price. There are better brands that do on a bit thicker. I mix it up with brands for my C. My skin looks fabulous for 59, so I will keep using C daily.

Don't use if you're a first timer with Vitamin C

I love this product a lot, it has helped with my melasma, I have fewer spots and the texture is better as well. This product is not for people who hasn't tried Vitamin C on its own, is not as torelable, especially with sensitive skin.

good vitamin C

A little too strong for my skin- needed a very hydrating moisturizer afterwards. But overall a very good product

Professional C Serum

No complaints about this product but not sure what it’s doing. I’ve been told Vitamin C is important for texture and clarity and my skin looks clearer. I like it though I may not buy again

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.

Everyday Staple

Go to vitamin C in my morning and night routines. I’ve seen a huge difference in my complexion and hope behind the scenes is helping my skins in more ways than visible to the eye! One star taken off for smell - it’s not the most pleasant smell out of all my products. I do like the oil consistency though. Will purchases again and again until I like something better.

Effective!

I have been using Vitamin C serum for a few years at the recommendation of my dermatologist and have definitely noticed my hyperpigmentation has become lighter. I switched to Obagi Vitamin C 20% from Skinceuticals because it's a little more affordable and it seems just as effective. It has a nice consistency and absorbs into my skin well.

Just started using

I've used the 15% Ogagi for a while now, and thought I'd step it up to 20%...Its still early, but so far it seems pretty good.

Works!

This serum works really well. I can tell the difference after a few days of use. My complexion looks smoother and less spotty. I use very little product to stretch it out. I keep in fridge to prolong effectiveness. Worth every penny!
