I'm not sure what gives me the glow either, but I noticed that after I use the SA and pat my face dry, it already looks like it's glowing. So maybe that's what does it for me. I've heard of Neostrata but I don't know if I've ever seen it in any of the drugstores near my house. I'll have to look again.
The BP I'm using is just the CVS brand. I'm not sure what the difference is between Dan's products and any others, though. I do know that he's mentioned on his site that 2.5% is enough, you don't need 5% or even 10%.
Just this afternoon I got some tretinoin in the mail. I ordered it a few weeks ago from an online pharmacy and forgot that I did. I'll let you guys know how it works for me!
