The reason our 5% BPO might work better than 10% Benzoyl Peroxide sold over the counter is because the one sold over the counter might may have 10% benzoyl peroxide in it but there’s so much add junk to make the shelflife last longer, preservatives, a lot of add junk, fragrance…It’s also a cream so the molecule is much larger and takes much longer to penetrate and doesn’t work quite as fast. For more reasons, watch the video. ;-) And for more info: https://www.cslaskincare.com/
