Hey, i have an uneven skin tone and areas of hyperpigmentation on my neck and face. I was wondering has anybody simultaneously used the regimen along with using 4% Hydroquinon to lighten the dark areas. If so, how did it work? And do you think it will be okay for me to use it while I'm on the regimen or will it possibly break me out ? It's bad, looks like I have a mustache but don't.
