I really think nothing will happen, don't respond but don't do it again. Just my advice. Many people do this and they are not going to waste the time or money prosecuting a first time offender who didn't order a quantity that would indicate intent to distribute. Further, they are not narcotics or schedule a substances.
I am a long time Retin-A user. I have also used the generic tretinoin. I have had great results. I get it from my dermatologist, I am very careful to use it as directed. In other words, I had to stagger my application in the beginning to prepare my skin to handle it. The first 2 weeks, I applied a pea-sized amount once every 3 days at night; the following two weeks, every 2 days; the last 2 weeks, every night. Just a pea sized amount. And I ALWAYS use sunscreen. Every day. Even if I am just looking out the window. Retin-A/Tretinoin makes your skin incredibly sensitive to the sun and can cause all sorts of sun damage and cellular damage to your skin if you expose it to the sun. So that means no tan - ever.
Eventually I did notice my face was getting too dry, so I reverted back to applying once every 2 nights and I still found I got great results and my skin looked amazing. The upside, in addition to amazing skin, is that it really does take away fines and wrinkles that I noticed after I turned 35. This may sound delusional on my part, but just trust me when I say that people think I am at least 5-10 years younger than I am. yes, a lot is genetics but I attribute it to the Retin-A as well.
But expect your skin to have a reaction to the Retin-A even if you follow this program to a tee. After a few weeks, your skin will be inflamed, itchy, flaky, dry, (lots of flaking around the jawline esp). I think that people who tolerate it well and who gradually introduce it in small doses only experience these side effects mildly and for a short period of time. I never had a terrible reaction or experience with flaking, inflammation. I also, oddly, preferred a particular company's tretinoin to brand name Retin-A and to other brands of tretinoin, but this is just my personal experience. Everyone is different.
The only other downside I faced was that once in a while my cheeks would turn very red, mostly when I was in a stuffy room. Almost like a rosacea. It doesn't happen often, and I am very very fair-skinned (so it might not happen to you if you aren't), but to me this downside is manageable considering the benefit.
Some people say it makes you lose hair or causes hair thinning. I can't tell if that's the case or not. Did I notice my hair thinning while using it - yes. (I am a woman so it's not male-pattern baldness). But my hair has gone through endless cycles of shedding/growth/shedding again since my late 20s (so nearly a decade). I doubt Retin-A is the cause, though it might not be helping the situation (the shedding is not that bad though, only I notice).
If you decide you want to continue using it, any dermatologist will prescribe it. You can say you used to use it for acne with another dermatologist and would like another prescription. Insurance will usually cover part of it for an acne diagnosis (which is a medical condition) but they won't for wrinkles (which is cosmetic).
