I absolutely love Dr Bronner's soaps. They are organic and free of nasty chemicals. No reason what so ever you should change that as your cleanser. However... and this is a big one

you NEED moisturiser! I personally wouldn't use sun screen every day. I think it can be too much of a good thing, and we do need some rays for general well being. That doesn't mean you should never wear it though!
I believe in keeping things simple, and I am wrinkle free at 33 so so far so good.
There is no need imo to spend loads of money on products, as you are mostly paying for marketing and packaging. I would always go with a cruelty free, organic, sulphate and paraben free option, which doesn't have to cost more than the rubbish that gets advertised on the TV.
Exfoliating is great a few times a week as well. You can easily make your own with either sugar or salt and some oil, or use a couple of aspirin if your skin can tolerate the chemical exfoliation from them.
Happy to hear you are seeing improvements already!
