I have been using Hypercare for about 3 weeks. It still burns some and a little irritation?

Do not apply any other deodorants or antiperspirants while you are using aluminum chloride hexahydrate. (Hypercare)

Initially a patient may need to use Hypercare three to seven times a week. After sweating becomes normal, the person may need to use it only once every one to three weeks. If skin irritation is a problem, a doctor may temporarily prescribe 1% hydrocortisone cream.
