Obagi Professional-C serum

I’ve used it daily for years and find its benefits so extraordinary

I had an on going order with this Company, They took money from my account on December 8th 2021 for two Obagi products I usually purchase from them, only to receive one of the items 3 weeks later. Been calling them since December 2021 they don’t answer their Telephone, have send several emails, wanting to know why they took my money for two items but they only send one item, they do not reply my emails, I had to go to my bank, to tell them to block this company from taking any money from my account, Please Please people do not order anything from them you will lose your money. This is the reason they are changing the Company’s name so they can continue scamming people. You will lose your money if you order anything from them. I lost my hard earned money from them.

Fave vitamin C

I have purchased this several times and strongly recommend it. The strong concentration gets the job done. This, more than any other product keeps my skin bouncy and clear-toned. It’s worth the price tag. I will save money elsewhere.
