I'm sure these have been asked before but please help me out, the search function is useless. Do you know:
1) Any studies comparing effectiveness of once a day vs twice a day?
2) Do foam in the morning interfere with the effectiveness of 5% Min at night in any way? (Delivery systems, etc)
3) Is Kirkland 5% liq from ebay good?
Thx!!!
