This is the best healing ointment I’ve ever used and I always have some handy, even when I travel. It was developed by nurses. I’ve recommended it to countless patients for moisture rashes in thigh folds, under breasts, etc. Many called back to say thanks - this works better than anything I’ve ever used! Apply a thin film to the rash after your evening shower and, in most cases, the rash will be practically gone the next day. It rarely takes more than three applications over three days for those rashes. If the rash persists or worsens, you should get an exam from your doctor or nurse. It has many other protective uses as described in the blurb. Recommend you don’t apply it to genital folds as it can cause discomfort due to menthol being one of its ingredients. If you’re a runner or cyclist, it’s wonderful to prevent below-the-waist perspiration rashes.
