First of all, congrats on taking the first step to clear skin!
1.) Biggest tip I can give you is to start slow! You need to see how your skin reacts to the BP -- even though you stated that you have BP experience, it still doesn't hurt to start slow and work your way up! I didn't start doing the regimine twice a day until around the second or third week I believe!
2.) Moisturize, moisturize, moisturize! My skin was extra dry when I started the regimine, and the best thing I did was added extra moisturizer to my face at night to counteract it! I even went as far as going to Wal-mart and buying Cetaphil moisturizer (an approved regimine moisturizer) just so I could add an extra bit at night!
3.) Don't get discouraged! It took me about 2 months before I saw results, so be sure to stick to the regimine! SO people see results in a week, others take months. I promise you, stick with it and you'll see great results!
Good luck on your journey! Be sure to give us lots of updates!
