I am also guilty of cleaning my face with rubbing alcohol... I did it all the time as a teen and never had any ill effects. All the toners I have tried seem to leave a weird residue or stickiness on my skin that I can't stand - so these days I skip any tone-type step. I just don't find it does anything for me.
I do still use rubbing alcohol on the hottest days of summer... I will rub it on my face and all over my arms and then stand in front of a fan. We live in California with no air condition... it's just a little indulgence for me.
I have read of people using and loving the ACV as a toner but... my concern would be, wouldn't you stink?? There is a site called
www.makeupalley.com where you can read reviews of various products (Which include home remedies) and one of them is ACV as toner. Very well reviewed.
The site is weird, though. Sometimes I can view it but sometimes it tells me you need to be a member... and I don't feel like signing up.
