Thanks for all the info, Luminareo! & During the season I spend anywhere from 2-3 hours out in the sun (plus any days I'm out with friends at the beach or just out in the sun) & interestingly enough I have never gotton a sunburn, just a nice tan. So I don't burn easy meaning you're probably right about not having to worry about the BP so much. But I did worry about it sweating off, will I be able to just cleanse when I get home & reapply the BP during my nightly routine? Instead of adding it back midday. I don't want to increase irritation. Also, do you know of anyone wearing makeup while on the routine? What foundations/powder would you suggest? I can't imagine leaving my house with a bare face..
I have been using Dan's BP regimen for more than 7 months now and it has worked really well for me. When I started, I had a similar problem as you do. I run outside in the afternoon after my classes for at least an hour most days. I also play soccer to 2 hours once a week. I never got a sunburn but I did ruin a couple of shirts from sweating off the BP. What I currently do is bring makeup removal wipes with me to class and before running, I remove everything on my face (including the BP). Then I just put a thin layer of moisturizer with SPF 15. This is a quick and easy way to prevent the BP from ruining my shirts and to prevent sunburn. As soon as I get home from my workout, I shower and reapply BP as my "night" regimen.
You can absolutely wear makeup while doing the regimen. Just make sure the BP is dry and that you moisturized really well before application. I would suggest a liquid or cream foundation because your skin is going to be very dry, especially for the first few months, and power tends to dry out your skin a little more.
Just remember to start with a small amount of BP and gradually build up. I would highly recommend purchasing jojoba oil to help combat the dry skin and flaking. You can definitely start with using the BP only at night as see how that works for you. It is a good way to introduce your skin to it slowly but eventually you might find that you need the BP in the morning and night. Either way, I would definitely wash your face and apply right after you get home from your after school sports. It is a somewhat tedious and time consuming regimen but if you stick to it, you will see results.
Hope this helps!
