We do not sell it online.  For our in office patients only, we sell in the office (legally) 4 prescription products - Biafine, Triluma, (when it's available), Latisse and Renova.  We price our Renova five dollars below Costco's price.    I don't do any advising, consulting, speaking or any other paid activity for any pharmaceutical, device, laser or cosmetic companies.  I've also personally used Renova or tretinoin for 20 years.   Hope this helps.   Dr. I
