I use the wipes, partially because I found these neat ones with peppermint oil ones that make my face feel cooler for a while after.
My acne got a lot worse and then improved a great deal, and I think the main contributing factor to it getting really, really awful at first was that I was eating a lot of crap food. Like, greasy/fried takeout two times a week or more, that sort of thing, but I was also using a lot of fatty condiments and whatnot. I'm vegan, so it wasn't like I was eating eggs and bacon with buttered toast and pizza and whatnot, but the General Tso's tofu I was noshing on v. frequently was, I think, the main culprit in terms of dietary contribution.
Not that I have silky smooth skin now, so I don't want you to get the wrong idea. I have a lot of issue with dry skin and with a bit of eczema, actually, which is new, but it likely has nothing to do with T. I gather it's a stress thing and that it runs in my family. The point is, you might never have perfect skin, so I don't want to mislead you.
I use Alba Botanica wipes, which I find for $3 at the grocery store. They make a Hawaiian one that smells amazing and works well for me, and then there's Acnedote by the same brand, which is the one with the peppermint. I live in Florida, so this time of year, anything that can cool me off a little is a plus. Testosterone has also had the added effect of making it much easier for me to get hotter, quicker, which seems to make my skin troubles flare up if I don't stay on top of it. I've accepted that I'll always get zits around my hairline. Always have, always will.
As far as home remedies, look up how to make a basic oatmeal scrub. I've done this a few times. Basically you make a paste out of oatmeal and water and let it sit on your face or wherever for a while. My skin definitely feels better after I do this. You can also add things like essential oils to the paste or even some vanilla or cinnamon from your kitchen, if you have it.
