Perfect serum
By Lizzie on Reviewed in the United States on August 14, 2025
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 !

Not that great
By Shopper Jan on Reviewed in the United States on May 27, 2025
I think the bottle I received was not as new as it should have been. It seemed ineffective. I used to be an esthetician and had my own business. If a product is good, it should be clear when you open it. Also , a potent vitamin C serum usually stings a bit when applied. Yellowing is a sign of oxidation. This seemed a bit too yellow, but I tried it anyway. I was definitely NOT IMPRESSED. There are better options that aren’t so expensive. Hint:keep your vitamin c serum in the refrigerator, it helps to keep it fresh longer.
