When you start, you're only supposed to use the BP once a day, and only 1/2 a pump, not a full pump.
You can be as generous with the cleanser and moisturizer as you want.
Dan has general guidelines on how often and how much to increase the BP, but everyone is different and sometimes needs to tweak it a little for it to work for them.
If you read some members' signatures on here, you'll see that they use other products in the morning while using The Regimen at night.
You just have to figure out what works for you.
In a nutshell, I've had mild/moderate adult on-set acne which began towards the end of 2009 (22 years old). Regarding my beliefs and the previous skincare/lifestyle changes I've tried, I've been conflicted, misinformed, resistant, allergic, and/or had my hopes up too high only to be let down. Many of my previous posts on here may reflect that. Considering I've never found an explanation as to why I developed acne in my twenties, whereas I've had flawless skin my entire life up until then, I claim to know nothing. I can only offer my humble advice based on my own personal experiences.
