I ordered the stuff months ago it took forever to get here so it finally got here I refuse the package, company then sent me the same thing there right now asking how my experience was I said I did not except the package, and sent it back I then sent a message asking where my refund was and they told me that it’s been too long for them to receive it back basically not to expect a refund, at that time I had already canceled, and now they sent me another shipment charging me again and I refuse the package again this is ********

Obaji C serum 20^

It is too soon to tell whether the current purchase has the same effect as the one I have been using for years. I have purchased the product from another supplier in the past and it takes about 6 weeks for me to see a difference. Will update the review at a later date.
