  2. I have been getting a rash when I get in the hot tub after menopause. I have tried all kinds of alternative options like lotions before getting in and I still break out. Do you think it is a result of skin changes during menopause

  3. Myself and my dad has got this hot tub rash and it’s very itchy and most of mine now look like white heads and very red round them? How do I know they are infected or am I making it worse by putting germolene on it? And they are spreading fast all over my body??
