I have used Obagi Vitamin C 20% for fifteen years and I wouldn’t miss one morning I am 71 years old. And as you can see, no wrinkles. I owe this to Dr John Mallen plastic surgeon who I introduced me to Obagi years ago Thank you

Most important items for your face and neck are vitamin c, retin A and sunscreen. I first purchased in my Derms office. I really like how it brightens my facial skin

Well worth the cost, very effective. It has evened out my skin tone. My skin feels and looks hydrated. Nothing that I have tried in the past compares to this product!

Excellent product I feel my skin is glowing more and feels more hydrated

This is my second bottle. I am amazed about the smell, efficacy and quality. 1. The smell is great. Usually when I buy a vitamin c it usually smells like I’m putting battery fluid. 2. Since it’s my second bottle, I know it’s slow process but I do notice it’s no irritation (redness or acne flare ups) 3. This vitamin c will last you more than a month without looking its quality. 4. Lastly, the customer support has been incredible. Yes you are paying $155 or so but you won’t go wrong.

Love this product in the AM to give my skin that smooth, gorgeous, glassy sheen pre-moisturizer & make up! I highly recommend it!

My face is practically glowing all day when I put the serum on in the morning. I never noticed much of a difference with other serums I've tried, but noticed immediately with this one. My skin loves it!

Obadiah makes a fantastic serum that is lightweight and goes on very smoothly. Although it’s not really inexpensive it’s worth every cent because of the quality of the product. It has worked so well on my skin and I’m very dry. It doesn’t take much product so it lasts a long time. I highly recommend!

I love the Vitamin C serum I have tried others, this is my Favorite

I do see a noticeable change; especially in my 'number 11' lines between my eyes. Sixty-two-yrs-old. Not sure if this or the plant based Kinetin moisturizer is blocking my pores. That I need to figure out- a definite negative for my skin.

My skin is glowing with this product It’s the best C serum I have used I love it!

2025-12-18

I use this vitamin C morning and evening and it keeps my skin hydrated. It’s like going to the spa daily!

2025-12-13

Truly amazing product. I’m a life time customer

I’m on my second bottle of C Serum and I have seen a noticeable improvement in my skin tone. I have been a lifelong outdoors person so I’ve done some damage to my skin. This serum has really evened out my brown spots to the point that I don’t see many left! I might start using it on my hands too.

The vitamin C seems okay, time will tell. However, no need for fragrance, would much prefer no added fragrances. Cannot yet decide if I will repurchase or go back to the $185, TBD.

LOVED this serum and will continue to use it. I have normal to oily mature skin and this serum is a game changer. It is absorbed quickly and brightens my skin without feeling oily. I plan to try the Light Hydrate and Clenziderm Pore Therapy next.

It has a very subtle and pleasant fragrance, it easily expands on the skin of the face and I love the curved shape of the serum expeller which makes it not water in the mouthpiece of the bottle. I give it 4 stars because I've been using it for a short time and I haven't been able to see so much difference yet but I have faith in it, and I will definitely buy it again when I finish 😀

This is my second bottle of the serum. My first purchase 3 months ago was a different formula. This is thinner and clear. It takes more serum to cover my face (so the bottle won't last as long), and I feel like I'm putting on water. There was no notice on the website about it being a new formula in the description. I had to call customer service to make sure what I got wasn't a mistake. I was really happy with the old formula; time will tell, but so far I'm not sure. Not happy with the lack of transparency.

2025-10-29

It’s about 10 days that I am using the product. It shows good results so far and I hope it continues.

I've been using this product for a long time. This latest bottle is clear instead of amber in color. It smells a little different and doesn't seem to be as concentrated with vit C as in the past when I've used the product. In the past, the day after microneedling I'd use vit C and I'd feel a little tingling. No tingling with this new formulation.
