I have owned several hot tubs in the past. I was typically only able to use it once or twice a week because my skin would get so dry I would end up with skin irritation. I suppose you could say I have sensitive skin. I started using Silk Balance when I purchased my recent hot tub. I have been using Silk Balance for over 4 months now. It is amazing! I feel like I can use the hot tub as often as I like. I am currently using my hot tub at least 4-5 times a week with no issues. It is such a great feeling to know that I can utilize my hot tub whenever I want without worrying about skin irritation. Thanks for a great product!!!!
