Why the last five failed and it wasn't your skin
Read what they were built to do. An antifungal is built to kill a fungus. A wash is built to strip. A wipe is built to scent. An anti itch cream is built to numb a nerve ending. Every one of those is a demolition job, and every one of them landed on skin that was only ever dry, thin and sore.
The labels do not protect you either. A review of 34 feminine hygiene wipes found contact allergens in every single product tested, including the ones sold as natural, sensitive and gentle. In one unscented version the fragrance had simply been swapped for scented botanicals: same allergens, new names on the back. Nobody polices those words. So the skin never gets one calm day to recover.
