Hi guys, this is my first post on this cite and I think I messed up pretty bad. I come from a family of 6 with 3 sisters (I'm a dude). I am 14 and one of my older sisters has moderate acne (18) while the other is on acutane with moderate scaring (17). I have decently mild acne mainly on my forehead and chin and was tired of it and didn't want to go through what my sisters went through. So I started following the acne.org regimen except with one difference... I accidentally used one of my sisters 10% benzoyl peroxide and my face has been embarrassingly red and stinging through out the school day. I looked through some forums, realized my mistake and have absolutely no idea what to do now... My face is puffy and even when I put more moisturizer on and put water on my face, it feels like I'm making the issue worse. Does anyone know how I should SAFELY get rid of my redness preferably before school tomorrow and also to continue with the regimen. I have everything I need except for non-Satan inducing benzoyl peroxide. I legitamitly can't feel my face as I am typing this. Pls help.

BTW  For some reason the part that stings the most is my cheeks where I have little to no acne.

Thanks ~~~~~~~~ <------- My face right now

Also any tips are appreciated
