I guess Dr. Spa isn't a for real doctor but plays one on the internet and a good one at that. If you read the information provided by the manufacturer of your bromine chemical system under the section concerning skin irritation, what does it say? That isn't a bad place to begin, your chemical company should be familiar with these issues. Also look at your spa owners manual, it may address skin irritations too. My advice is shower off soon after you soak. Try to keep your time in spa to 15 minutes and then shower. In hot spa water your pores dilate, which is good, but could trap stuff once you cool off so you have to get that stuff off your skin out of your pores. I think east texas spas sells a special luffa for such. I have to say, active oxygen system is new to me.
