I am a physician, though not a dermatologist. I wanted to tell you how well your regimen has worked for my teenage kids. My 16 year-old son had moderately severe acne and poorly controlled on oral antibiotics, topical Retin-A and a benzoyl-peroxide wash. He was frustrated so I did a little loooking around and found your regimen. Since beginning the Kerns regimen, his acne has essentially cleared with only an infrequent pustule. He has been off oral antibiotics for many months and no longer uses Retin-A. My 14 year-old daughter started having some pustules so she is now using the regimen and is also completely clear. We are all, needless to say, very happy with the results. Thanks for your work and for making this program available.
