Because IC patients often struggle with overly sensitive skin, as well as tenderness in the urethra, vulva, perineum etc., it's vital to use a soap which is hypoallergenic and created specifically for sensitive skin. Heavily perfumed and harsh soaps, in both bar or liquid form, are notorious for triggering flares. Even milder soaps and bubble baths have been known to irritate those tender tissues. We strongly suggest Basis, Dove and Very Private Body Wash, especially for patients struggling with vulvodynia and prostatodynia.
