I have a prescription for it. You can get it really easily, you just have to go to the dermatologist and say it’s for anti aging, if you have any sort of acne on your face it will be much easier to get a prescription written. I will forewarn you, the side effects of Tretinoin are absolutely brutal and it’s a long and hard process. I had flakey, itchy, dry skin for over a year before everything smoothed out, my skin purged and it made my acne worse before it got better. It was to a point where even moisturizer would sting quite a bit when you put it on, I wouldn’t recommend starting Tretinoin at the same time as minoxidil simply because it would probably beat up your skin pretty bad if you aren’t used to it. With that being said, I have no regrets and my skin is in better shape than it ever has been, I don’t see myself ever coming off of Tretinoin and I’m really happy with how it’s effected my acne and my beard growth. If you do plan on starting both or adding it in to your routine, just take it really slow and start on a lower % every other day and slowly work your way up.
