Serum directions

[#1]

When a serum says apply AM and PM, but you only apply it at night, does it really speed up the process by putting it on both day and night? Because I don't want to wear serum in the morning under my makeup and look completely greasy so I only put it on at night...but haven't seen results yet. (I've been using Origins Mega-Bright Serum for 2 weeks for acne scars).

So what I'm asking is, is it worth looking slightly oily with makeup on to really follow the directions of what the product is telling me to do?

That's odd. It shouldn't be oily. I use it twice a day and I am on the third bottle of the stuff and I haven't seen much results.  I really want to love it but I still have many dark spots. I mean I saw a significant difference the first two weeks and then it kind of just stopped. But anywho I would suggest using it twice a day and if nothing happens move on. Also try using less and make sure your skin fully absorbs it before you put on other products.
