Are crystal deodorants made out of 100% potassium alum a good alternative to antiperspirants?
1 Answers
Antiperspirants contain aluminum salts that temporarily block sweat glands to reduce sweat production, while crystal deodorants rely on the astringent properties of potassium alum to help reduce bacterial growth and reduce odor. They can be a valuable alternative to antiperspirants. However, they can cause skin irritation due to the astringent properties. It will be a matter of testing and verifying whether it works well for you. Best, Chris
