I actually only rinse my face with cold water while in the shower (whether it be morning or night or sometimes both), but try out different things for a couple weeks. Note what works and doesn't work for you.
I hope these tips help you. I've read and spoken to so many people who have resorted to the water only regimen and have experienced overwhelmingly positive results in their skin. The best thing for you to do right now is completely turn away from all of the stuff you're using for your acne and just letting your skin take a rest.
If you do plan on using any other products like cleansers and stuff, you may want to wait a few weeks to a month to let your skin recover a bit and see how you do without products. The worst thing you could to do to your skin is use a product that doesn't work and forgets your skin up, and then switch to a new product immediately that can't even do it's job right because your skin is so forgeted up from the previous product. Acne-free skin is definitely not an overnight achievement and takes weeks to months, so I wish you luck on your journey lol
