Yeah, I mean, the doxocy -- let me sit back, the tetracycline family as a whole impacts a number of processes that stop the inflammatory cascade of rosacea, that's been understood for many years in terms of different proteins that get cleaved, the cathelicidin pathway. And without getting too scientific, a lot of the cell lines that are progressing the process of rosacea. So both doxycycline and minocycline have been proven effective at an optimal dose because for one, there's no bacterial targets, so there's no action as an antibiotic. It's more an anti-inflammatory dose. But the problem is above a certain threshold, the medication, whether it's doxycycline, or minocycline, can have antibiotic properties, which can lead to consequence down the road, which is what led to the cultivation of Oracea at that dosage. Now, the way minocycline will work at this dosage in the DFD product, you know, the DFD-29 product, will be in a very similar directed fashion against the process that makes rosacea and the safety of it will allow it to be used, again, year long, if you will, whatever indication comes from it. The long term studies, you know, for 52 weeks, and everything else that goes along with this class of drugs, tells us that we have a safety profile we can rely on. So I think in the end, rosacea patients, you think about an average 30 something old, they have a high copay, high deductible. I'd rather treat them with something that I know will work for the long run, and not have to see them back in the office to fine tune them, and let them do well on the medication that's going to serve the purpose of treating the process of their disease, not just the symptoms. So I hope that makes sense. I don’t want to be [scientific] for you.
