Obagi Medical Professional-C Serum 20% (1 oz.)

This is my first time buying 20%. I’ve been using the 15% for a year. I can definitely tell a difference between the two. The packaging and dropper are very basic but that’s fine because the product is fantastic.

Vitamin C serum

Best on the market

After trying all the medical grade skin care products Obagi continues to be the best. Scent, application, benefit is superior to any others, personally. Highly recommend.

Great product!

I have been using C-vitamin in my skincare routine for almost two years. Obagi is the second brand I have tried for the Vitamin C product. Before that, I was using Cellex-C Advanced C vitamin serum which I loved, but I also wanted to try out other brands to know if they could be even better. I did not notice much difference between Cellex C and Obagi; they are both equally good and gave me the same results, and from now on, I will buy whichever has a better price when I need it. Pros - it does soften fine lines and evens skin tone over time of frequent every morning use. The best preventative skincare product, even if you don't see a noticeable difference. Cons - It's not a product that can sit on your shelf forever, the consistency and smell of the product change. I started using more of the product than necessary because it began to oxidize. It lasted me 4.5 months, but it could have been more than that if the formula had been more stable. For those with oily skin - it will make your skin look more oily.

Good Serum

This serum is pretty good, but I think it did cause some breakouts.

Buy this!

My favorites of all time. Use in the morning under your moisturizer for an all-day glow!

A keeper

I had read that Vitman C serums improved and protected skin. I drug my feet trying it as I had a little sticker shock at the price. I purchased during an Obagi sale and it is a forever staple now in my regimen-several people have commented on  the glow of my skin and I have seen a significant improvement in texture and healthiness of my skin.

My favorite brightening product

Love the absorption and consistency. Near instant effects for me, makes my skin brighter and more supple. No residue, highly recommend.
