Hi Jose, The idea for heat treatment came from a faculty member at University of Illinois who authored several papers of RKN in cold climates. I had originally called him seeking information for a cold treatment (essentially freezing the roots) for RKN. He said he didn't think it would work. The cold slows down RKN activity (lengthen it's reproductive cycle), but it didn't necessarily stop it. Even though the Southern RKN is found in crops in the area, they are well controlled. Also, I've had good luck with just air-drying the roots (roots laid out on a breezy, warm day for 2 hours). You may want to eliminate this part (or try some with and some without the air-drying). This will help determine the effectiveness of the cold process. Good luck, ~james

littleredhen - I helped a young girl in my office whose acne was flaring constantly - she was using St. Ives. I am Canadian so product choices are different (more limited usually). Eventually she found she could tolerate some of the Vichy products - I think you can get them in the US. Or you could try Cetaphil - my skin is very, very dry so does not work for me. But most important thing for you is to establish a proper skin care routine - and toss the Noxzema. I am 55 and everyone used it when I was a teen but long term use can result in problems later on. Re acne around your mouth, have you considered your tooth paste (tartar control is a devil for this); are you placing a phone received against your mouth - this is known to cause acne - I got around that by placing moleskin around the mouthpiece daily - and cleaning it - and of course pillowcases. Also some foods - acid types such as grapefruit can cause a problem - me for example. jannie - At 55 I feel your pain and I am allergic to most things. I note that you live in NY - maybe check out some of the Erno Laszlo products from the 8:30 clock. Also you might want to avoid moisturizers with a combined SPF - go separate. I use a night cream during day to avoid the combo product.

My daughter has had the same struggle. Starting in 9th grade, constantly going to the dermatologist. Every antibiotic and prescription cream you can think of. They all worked, for awhile, then bad breakouts again. Acutane was the final option after nothing else continuously worked. It's usually a 6 month run. 4 months into it, I was stunned at how clear she was, BUT, big problem. Made her liver enzymes plummet. To the point where the nurse was panicked on the phone and said DO NOT let her take one more pill. While on acutane, you have to have blood work done every month. That was 2-3 years ago. Since then, more antibiotics, creams, etc. We finally quit going. Then, a new store opened in our area. Called Ulta. They have a facial cleansing kit by MD Formulation. It's the adult anti-acne kit. She's been using it for 2 months, along with changing make-up brand to Bare Escentuals. I am amazed at the difference. All those years, and drugs and creams, and tears. At least so far, this is working. They also have teen anti-acne kit, anti-aging kits, etc. I would give this a try before antibiotics. I hated that she was on constant antibiotics for a couple of years. Well, anyhow, I hope this helps some. Ulta.com is the web address if you want to check them out. I had never heard of them til they opened up last fall so I don't know if they're new, or just new to our area. Good luck. Katlan

I have had acne issues my whole life and attributed it to being allergic to acidic drinks and foods like tomato sauce, orange juice, grapefruits, etc. Well, come to find out I accidentally tried the Clear & Clean tube that was sitting in our medicine cabinet. I have not had one outbreak since using it every day. Even better, I can now enjoy all that food I have been avoiding for decades. I highly recommend it to anyone. BTW, I also purchased and tried ProActive with no luck. Hope This Helps George Here is a link that might be useful: At Home Teeth
